Description:
FIELD OF THE INVENTION 
     The present application relates to field of camera modules, and further relates to a photosensitive assembly and a photosensitive assembly jointed panel manufactured by a molding process, a manufacturing method thereof, and a camera module having the photosensitive assembly. 
     BACKGROUND OF THE INVENTION 
     Molding and packaging technology of a camera module is a newly developed packaging technology based on traditional COB packaging. As shown in  FIGS.  1 A to  1 C , a circuit board is packaged by using the existing integrated packaging technology. In this structure, a packaging portion  1  is packaged in a circuit board  2  and a photosensitive chip  3  by an integrated packaging way to form an integrated packaging assembly, and the packaging portion  1  covers a plurality of electronic components  201  of the circuit board  2  and a series of leads  202  electrically connecting the photosensitive chip  3  and the circuit board  2 , which enables the length, width, and thickness dimensions of the camera module to be reduced, and assembly tolerances can be reduced, and a lens or a lens assembly positioned above the integrated packaging assembly can be mounted flatly and the problem that dust attached to the electronic components affects the imaging quality of the camera module is solved. 
     More specifically, as shown in  FIGS.  1 A and  1 B , in order to improve production efficiency, the integrated packaging assembly is generally produced by a jointed panel production way, that is, a plurality of the integrated packaging assemblies are produced at one time. More specifically,  FIGS.  1 A and  1 B  show a way of producing the integrated packaging assembly by using a molding die to perform jointed panel production. Wherein, the molding die includes an upper die  101  and a lower die  102 , and one of the circuit board jointed panels is placed in the lower die  102  of the molding die, the circuit board jointed panel includes a plurality of rows of the circuit boards, each row of the circuit boards includes a plurality of the circuit boards  2 , and each of the circuit board  2  is operatively connected to the photosensitive chip  3 . The upper die  101  and the lower die  102  are clamped to form a molding cavity, so that the upper die  101  is pressed on the circuit board jointed panel, and is corresponding to the two end sides of the photosensitive chip  3  on each row of the circuit boards, and two flow passages  103  and  104  are formed in the upper die, and the upper die  101  has a plurality of the bumps  105 , an intermediate flow passage  106  is formed between two adjacent bumps  105 , so that the plurality of the intermediate flow passages  106  extend between the two flow passages  103  and  104 . In the molding process, a fluid-like packaging material  4  flows forward along with the two flow passages  103  and  104 , and fills into the intermediate flow passage  106  between two adjacent bumps  105 , so that the region between two adjacent photosensitive chips  3  is also filled with the packaging material  4 , thereby after the packaging material  4  is cured, the packaging portion  1  can be formed on the corresponding each of the circuit boards  2  and each of the photosensitive chips  3 , a light window located in the middle of the packaging portion  1  is formed at a position corresponding to each of the bumps  105 , and these packaging portions  1  are integrally molded to form a one-piece structure, as shown in  FIG.  1 C . 
     Referring to  FIG.  1 E , the thermosetting packaging material  4  has a curing time T in the molding process, as time passes, its viscosity decreases to the lowest point, and then gradually rises to the highest point to completely cure. Ideally, when the packaging material  4  has a low viscosity, the packaging material  4  is to fill the flow passages  103 ,  104 , and  106 , while the packaging material  4  still flows forward when the viscosity is large, the friction thereof to a lead  202  between the circuit board  2  and the photosensitive chip  3  is relatively large, which may easily cause deformation and damage of the lead  202 . 
     In the above-mentioned molding process, the packaging material  4  is a thermosetting material, and enters the two flow passages  103  and  104  after being melted, and is cured under the action of heating conditions. However, in actual production, it has been found that, during the molding process, when the packaging material  4  flows forward along with the two flow passages  103  and  104 , if the widths of the two flow passages  103  and  104  is small, it may cause problems. 
     More specifically, because the packaging material  4  is a fluid having a predetermined viscosity, the dimensions of the two flow passages  103  and  104  are relatively small, and for example, the flow passage  103  may be a narrow flow passage, the flow rate in the flow passage  103  is relatively small, and the friction generated by the inner wall of the flow passage  103  on the fluid-like packaging material  4  in it has a relatively large effect on flow velocity of the fluid-like packaging material  4 , so the flow velocity of the packaging material  4  in the flow passage  103  is relatively slow. In this way, during the curing time T of the packaging material  4 , the packaging material  4  in the flow passage  103  may not flow from the feeding end to the terminal end within the curing time T, so that some certain position of the flow passage  103  cannot be filled, as the region S shown in  FIG.  1 D , thereby it is impossible to form a one-piece structure of the packaging portion  1  with a series of complete shapes between the upper die  101  and the lower die  102 , and at the position corresponding to the region S, the packaging portion  1  forms a gap, so that it is not possible to form an all-around closed light window. In addition, if the width of the flow passage  104  is narrow, a case as shown in  FIG.  1 D  may also appear in the flow passage  104 . 
     In addition, if, for example, the packaging material  4  in the flow passage  103  flows too slowly forward, when the viscosity is relatively large, it still flows forward in the flow passage  103 , resulting in the frictional force on the lead  202  through which the packaging material flow is large, so that the lead  202  is deflected forward with a large level, thereby the lead  202  is easily deformed and damaged, and is easily detached from a bonding pad. 
     As shown in  FIG.  1 F , it is a camera module packaged by using the existing integrated packaging technology, which includes a packaging portion  1 , a circuit board  2 , a photosensitive chip  3 , a filter  5 , and a lens assembly  6 . In this structure, the packaging portion  1  is packaged in the circuit board  2  and the photosensitive chip  3  by an integrated packaging way, thereby forming an integrated packaging assembly, and the packaging portion  1  covers a series of electronic components  201  of the circuit board  2  and a series of leads  202  electrically connecting the photosensitive chip  3  and the circuit board  2 , which enables the length and width dimensions and thickness dimensions of the camera module to be reduced, assembly tolerances to be reduced, and the lens assembly  6  positioned above the integrated packaging assembly to be mounted flatly, and the problem that the dust attached to the electronic component  201  affects the imaging quality of the camera module to be solved. 
     In addition, in order to facilitate demolding, an inner surface of the packaging portion  1  that is generally formed extends integrally and obliquely from the photosensitive chip  3 , which will cause the area of the top surface of the packaging portion  1  to decrease, and the top side of the packaging portion  1  needs to be used for mounting an upper optical device of the camera module, such as the lens assembly  6  described above, or additional components, such as lens holders, etc. However, the small-area top surface of the packaging portion  1  may not provide sufficient mounting surfaces for the upper optical device of the camera module, so that these upper optical devices are unable to be stably mounted and glue is prone to overflow on the mounting surface. 
     In the manufacturing process of the integrated assembly shown in  FIG.  1 B , a circuit board  201  to which a photosensitive chip  3  is connected is placed in a die, and a bump  105  is pressed on the photosensitive chip  3  as an indenter. Flow passages  103 ,  104 , and  106  substantially form a groove  107  surrounding the bump  105 , and a fluid-like packaging material  4  is filled into the groove  107 , after the fluid-like packaging material  4  being cured, the packaging portion  1  is formed, and a through hole of the packaging portion  1  is formed at the position corresponding to the bump  105 . The bump  105  has an inclined outer surface  1051 , so as to form an integrally extending inner surface of the packaging portion  1 . 
     However, in the integrated packaging process, the fluid-like packaging material may enter between the photosensitive chip  3  and the bottom surface of the bump  105 , thereby causing the packaging material to reach a photosensitive region of the photosensitive chip  3 , forming a “flash”, thereby affecting the photosensitive effect of the photosensitive chip  3 . Furthermore, a filling groove  1071  is formed on the bottom side of the groove  107  between the photosensitive chip  3  and the inclined outer surface  1051  of the bump  105 , in the integrated packaging process, the packaging material enters the filling groove  1071 , and the inclined outer surface  1051  of extends obliquely the bump  105  tends to guide the packaging material into the filling groove  1071 , resulting in the filling groove  1071  having a greater volume, and the fluid-like packaging material generates a relative large pressure force and intensity of pressure, therefore the probability that the packaging material enters between the photosensitive chip  3  and the bottom surface of the bump  105  is increased, so that the packaging material is likely to pollute the photosensitive region of the photosensitive chip  3 , thereby affecting the photosensitive performance of the photosensitive chip  3 . Moreover, if in order to reduce the occurrence of “flash”, the pressure force of the bump  105  pressed on the photosensitive chip  3  is increased, the photosensitive chip  3  may be damaged.

In addition, the fluid-like molding material  14  is injected into the base jointed panel molding guide grooves  215  on the top side of the circuit board jointed panel  1100 , so that the one-piece molding base  1200  is formed on the top side of each row of the circuit boards  11  and each row of the photosensitive elements  13 . 
     It can be understood that the circuit board positioning groove  2121  may also be provided in the first die  211 , that is, the upper die, for mounting and fixing the circuit board jointed panel  1100 , and the light window molding portion  214  and the base jointed panel molding guide groove  215  may be formed in the second die  211 , and when the first die  211  and the second die  212  are clamped, the molding cavity  213  is formed. The circuit board jointed panel  1100  may be arranged face upward in the upper die, and the fluid-like molding material  14  is injected into the base jointed panel molding guide groove  215  on the bottom side of the circuit board jointed panel  1100  that is inverted, so that the one-piece molding base  1200  is formed on the bottom side of the circuit board jointed panel  1100  that is inverted. More specifically, when the first die  211  and the second die  212  are clamped and a molding step is performed, the light window molding portion  214  is superimposed on the top surface of the photosensitive element  13  and closely adhered, so that the fluid-like molding material  14  is prevented from entering the photosensitive region  1311  on the top surface  131  of the photosensitive element  13  on the circuit board  11 , so that the light window  122  of the one-piece molding base  1200  can be finally formed at a position corresponding to the light window molding portion  214 . It can be understood that the light window molding portion  214  may be a solid structure or a structure having a groove shape inside as shown in the figures. 
     It can be understood that the molding surface of the first die  211  forming the base jointed panel molding guide groove  215  can be configured as a flat surface and is on same plane. In this way, when the molding base  12  is cured and molded, the top surface of the molding base  12  is relatively flat, so as to provide flat mounting conditions for optical components such as drivers, lenses, and fixed lens barrels above the photosensitive assembly  10  of the camera module  100  to reduce the tilt error of the camera module  100  after assembly. 
     It is worth mentioning that the base jointed panel molding guide groove  215  and the light window molding portion  214  can be integrally molded in the first die  211 . Alternatively, the first die  211  further includes a detachable molding structure, and the molding structure is formed with the base jointed panel molding guide groove  215  and the light window molding portion  214 . In this way, according to the shape and dimension requirements of the photosensitive assembly  10  such as the diameter and thickness of the molding base, the base jointed panel molding guide grooves  215  and the light window molding portion  214  of different shapes and dimensions can be designed. In this way, only the different molding structures need to be replaced, then the manufacturing equipment can be adapted to be applied to the photosensitive assembly  10  with different specifications. It can be understood that the second die  212  may also include accordingly a detachable fixing block to provide the grooves  2121  with different shapes and dimensions, so as to facilitate the replacement of the circuit board  11  adapted to different shapes and dimensions. 
     It can be understood that the molding material  14  is a thermosetting material. The molding material  14  is changed into a fluid state by heating and melting the thermosetting material in a solid state. During the molding process, the thermosetting molding material  14  is cured through a further heating process, and can no longer be melted after be cured, thereby forming the one-piece molding base  1200 . 
     It can be understood that, in the molding process of the present application, the molding material  14  may be a block shape, a granular shape, or a powder shape, which is changed to fluid in the molding die  210  after being heated, then is cured to form the one-piece molding base  1200 . 
     More specifically, each of the base jointed panel molding diversion grooves  215  of the present application has a first diversion groove  2151  and a second diversion groove  2152  that are substantially parallel to each other, and a plurality of filling grooves  2153  extends between the first diversion groove  2151  and the second diversion grooves  2152 , wherein the filling grooves  2153  are formed between two adjacent light window molding portions  214 , and as shown in the figure, the base jointed panel molding guide groove  215  has seven filling grooves  2153 , and six light window molding portions  214  are located between two adjacent filling grooves  2153 . The molding material  14  flows along with the first diversion groove  2151  and the second diversion groove  2152  from the feeding end  215 A to the terminal end  215 B, and the molding material  14  can fill each of the filling grooves  2153 , so that the one-piece molding base  1200  is formed after the molding material  14  is cured. 
     As shown in  FIGS.  7 A to  10   , it is a schematic view of a manufacturing process of the photosensitive assembly jointed panel  1000  of the camera module  100  according to this preferred embodiment of the present application. As shown in  FIG.  7 A , the molding die  210  is in a die clamping state, the circuit board jointed panel  1100  to be molded and the solid molding material  14  are ready to be in place, the solid molding material  14  is heated, thereby when the molding material  14  is melted into a fluid state or a semi-solid and semi-fluid state, it is sent to the base jointed panel molding guide groove  215 , flows forward along with the first diversion groove  2151  and the second diversion groove  2152 , and fills the filling groove  2153  between two adjacent light window molding portions  214 . 
     As shown in  FIGS.  8  and  9   , when the base jointed panel molding guide groove  215  is completely filled with the fluid-like molding material  14 , the fluid-like molding material  14  is cured and molded into the one-piece molding base  1200  integrally molded on each row of the circuit boards  11  and each row of the photosensitive elements  13  through a curing process. 
     As shown in  FIG.  10   , after the molding material  14  is cured to form the one-piece molding base  1200 , a demolding process of the present application is performed, that is, the die fixing device  230  makes the first die  211  and the second die  212  to be away from each other, so that the light window molding portion  214  is separated from the one-piece molding base  1200 , thereby the light window  122  corresponding to each of the photosensitive elements  13  is formed in the one-piece molding base  1200 . 
     As shown in  FIGS.  4  to  6   , the prepared photosensitive assembly jointed panel  1000  can be further cut to obtain an individual photosensitive assembly  10 . Each of the photosensitive assemblies  10  includes at least one circuit board  11 , at least one photosensitive element  13  and the molding base  12  integrally molded on the circuit board  11  and the photosensitive element  13 . Each of the circuit boards  11  includes a rigid region  111  and a flexible region  112  combined with each other. That is, each of the circuit boards  11  can be implemented as a rigid-flex combined board in this embodiment of the present application. Wherein, the molding base  12  is integrally molded on the rigid region  111  of the circuit board  11  and at least a part of the non-photosensitive region  132  of the photosensitive element  13 , and forms the light window  122  that provides a light path for the photosensitive region  131  of the photosensitive element  13 . 
     It is worth mentioning that the manufacturing method of the photosensitive assembly jointed panel  1000  of the present application is suitable for manufacturing the photosensitive assembly  10  with a small size. Therefore, in the molding process, the volumes of the first diversion groove  2151  and the second diversion groove  2152  are relative small. As can be seen from  FIGS.  7 A to  10   , the cross sections of the first diversion groove  2151  and the second diversion groove  2152  are substantially trapezoidal. Wherein, the widths of the bottom ends of the first diversion grooves  2151  and the second diversion grooves  2152  are limited in size and cannot be widened. 
     Therefore, according to the embodiment of the present application, an inner surface of the one-piece molding base  1200  facing the light window  122 , that is, a first side surface  1201  of the first diversion groove  2151  and a second side surface  1202  of the second diversion groove  2152  are provided as a two-end structure. 
     Specifically, as shown in  FIGS.  6 A and  6 B , the first side surface  1201  includes a first partial surface  1203  provided adjacent to the photosensitive element  13  and a second partial surface  1204  connected to the first partial surface, and a first angle of the first partial surface  1203  relative to an optical axis of the camera module is greater than a second angle of the second partial surface  1204  relative to the optical axis. That is, from the perspective of  FIGS.  6 A and  6 B , the first partial surface  1203  and the second partial surface  1204  extend from bottom to top, and the inclination of the first partial surface  1203  is greater than that of the second partial surface  1204 . In this way, because the second partial surface  1204  is inclined toward the light window direction with respect to the first partial surface  1203 , the cross-sectional area of the first diversion groove  2151  is increased, thereby further increasing the volume of the first diversion groove  2151 . 
     Similarly, the second side surface  1202  includes a third partial surface  1205  provided adjacent to the photosensitive element  13  and a fourth partial surface  1206  connected to the third partial surface, and a third angle of the third partial surface  1205  relative to the optical axis of the camera module is greater than a fourth angle of the fourth surface portion  1206  relative to the optical axis. That is, from the perspective of  FIGS.  6 A and  6 B , the third partial surface  1205  and the fourth partial surface  1206  extend from bottom to top, and the inclination of the third partial surface  1205  is greater than that of the fourth partial surface  1206 . In this way, because the fourth partial surface  1206  is inclined toward the light window direction with respect to the third partial surface  1205 , the cross-sectional area of the second diversion groove  2152  is increased, thereby further increasing the volume of the second diversion groove  2152 . 
     Preferably, in the embodiment of the present application, the cross-sectional design of the first diversion groove  2151  and the second diversion groove  2152  has symmetry, that is, the first angle of the first partial surface  1203  is equal to the third angle of the third partial surface  1205 , the second angle of the second partial surface  1204  is equal to the fourth angle of the fourth partial surface  1206 . Considering the influence of the stray light of the camera module, the first angle and the third angle are set to 3°˜80°. In addition, considering other factors of the module process and the structure and material characteristics of the molding base of the camera module, the second angle and the fourth angle are set to 0°˜20°. 
     Here, it should be noted that the second angle and the fourth angle in the embodiment of the present application are further preferably set to 0 degrees, that is, the second partial surface  1204  and the fourth partial surface  1206  extend perpendicular to the surface of the photosensitive element  13  upwardly. On one hand, it can maximize the cross-sectional region of the diversion groove, on the other hand, it will not affect the light incident on the photosensitive chip of the camera module. 
     Those skilled in the art can understand that, on one hand, the cross-sectional shape of the diversion groove will affect the flow of the molding material, on the other hand, it also directly determines the cross-sectional shape of the resulting molding base. 
     By the two-stage design of the first side surface  1201  and the second side surface  1202 , that is, by the smaller inclination of the second partial surface  1204  relative to the first partial surface  1203 , and the smaller inclination of the fourth partial surface  1206  relative to the third partial surface  1205 , it can further increase the area of the upper surface of the molding base, so that it is convenient to support other components of the camera module such as a lens holder. 
     Therefore, in the embodiment of the present application, in addition to considering the influence of specific shape and size factors on the cross-sectional shape of the diversion groove, the influence of the shape and size factors on the shape of the molding base needs to be further considered. 
     Specifically, since the molding base needs to cover a connecting wire  15 , the heights of the first side surface  1201  and the second side surface  1202  in a direction perpendicular to the surface of the photosensitive element  13  need to be further defined. 
     Preferably, in the embodiment of the present application, a first height of the first partial surface  1203  in a direction perpendicular to the surface of the photosensitive element  13  and a third height of the third partial surface  1205  in the direction are 0.05 mm˜0.7 mm. In this way, it can be ensured that the formed molding base can cover the connecting wire  15  well. In addition, considering the molding base as a whole to cover the connecting wire  15  and structural factors that further supports the lens holder, a second height of the second partial surface  1204  in a direction perpendicular to the surface of the photosensitive element  13  and a fourth height of the fourth partial surface  1206  in the direction are 0.02 mm˜0.6 mm. 
     Through the second partial surface  1204  and the fourth partial surface  1206 , the height of the molding base can be further increased, which avoids pressing the connecting wire  15  when installing other components of the camera module, such as the lens holder, thereby affecting the performance of the camera module. 
     In this way, by setting the side surface of the diversion groove to a two-stage shape, a smooth flow of the molding material as a fluid in the diversion groove can be ensured. Specifically, the fluid-like molding material  14  can flow forward along the first diversion groove  2151  and the second diversion groove  2152  and the entire base jointed panel molding guide groove  215  is filled with the molding material  14  before the molding material  14  is cured. 
     Accordingly, the molding process of the present application obtains the photosensitive assembly jointed panel  1000 , including: one or more rows of the circuit board  11 , one or more rows of the photosensitive elements  13 , and one or more one-piece molding bases  1200 . Each row of the circuit boards  11  includes one or more circuit boards  11  arranged side by side, each of the circuit boards  11  includes the rigid region  111  and the flexible region  112  combined with each other. Each of the one-piece molding bases  1200  is integrally molded on a row of the circuit boards  11  and a row of the photosensitive elements  13  and forms the light windows  122  that provide a light path for each of the photosensitive elements  13 . Wherein, a portion  1200 A of the one-piece molding base corresponding to a first end side of the one-piece molding base  1200  adjacent to the flexible region  112  has a first side surface  1201 , the first side surface  1201  includes a first partial surface  1203  provided adjacent to the photosensitive element  13  and a second partial surface  1204  connected to the first partial surface, and a first angle of the first partial surface  1203  relative to an optical axis of the camera module is greater than a second angle of the second partial surface  1204  relative to the optical axis. A portion  1200 B of the one-piece molding base corresponding to an opposite second end side of the one-piece molding base  1200  away from the flexible region  112  has a second side surface  1202 , the second side surface  1202  includes a third partial surface  1205  provided adjacent to the photosensitive element  13  and a fourth partial surface  1206  connected to the third partial surface, and a third angle of the third surface  1205  relative to the optical axis of the camera module is greater than a fourth angle of the fourth surface  1206  relative to the optical axis. Wherein, the first end side of the one-piece molding base  1200  corresponds to a combined side of the rigid region  111  and the flexible region  112  of the circuit board  11 , that is, the proximal side near the flexible region  112 ; and the second end side of the one-piece molding base  1200  corresponds to the distal side of the circuit board  11  away from the flexible region  112 . 
     A single photosensitive assembly  10  can be obtained after the photosensitive assembly jointed panel  1000  is cut, wherein, in the cutting step, it can be cut on the two wing sides of the one-piece molding base  1200  except for the first end side and the second end side to obtain the molding base  12 , and the portion  1200 B of the molding base corresponding to the second end side is not cut, so that the photosensitive assembly  10  having a portion  1200 C of the one-piece molding base on a pair of opposite wing sides is obtained. 
     As shown in  FIG.  6 A , correspondingly, the photosensitive assembly  10  includes the circuit board  11 , the photosensitive element  13  and the molding base  12 . The circuit board  11  includes the rigid region  111  and the flexible region  112  combined with each other. The molding base  12  is integrally molded on the circuit board  11  and the photosensitive element  13  and forms the light window  122  that provides a light path for the photosensitive element  13 . The circuit board  11  and the photosensitive element  13  are connected through a series of connecting wires  15 . A portion  12 A of the molding base corresponding to the first end side of the molding base  12  adjacent to the flexible region  112  has a first side surface  1201 , the first side surface  1201  includes the first partial surface  1203  provided adjacent to the photosensitive element  13  and the second partial surface  1204  connected to the first partial surface, and a first angle of the first partial surface  1203  relative to the optical axis of the camera module is greater than a second angle of the second partial surface  1204  relative to the optical axis. A portion  12 B of the molding base corresponding to the opposite second end side of the molding base  12  away from the flexible region  112  has a second side surface  1202 , the second side surface  1202  includes the third partial surface  1205  provided adjacent to the photosensitive element  13  and the fourth partial surface  1206  connected to the third partial surface, and a third angle of the third partial surface  1205  relative to the optical axis of the camera module is greater than a fourth angle of the fourth surface portion  1206  relative to the optical axis. 
     As shown in  FIG.  6 B , accordingly, in order to further reduce the size of the photosensitive assembly  10 , at least a part of the photosensitive assembly  10  on the opposite second end side of the molding base  12  away from the flexible region  112  is suitable for being removed, such as cutting with a knife, or grinding. Here, those skilled in the art can understand that the arrangement of the side surfaces is the same as that shown in  FIG.  6 A , and will not be repeated here. 
     By smooth flow of the molding material  14  in the diversion groove, in the molding process, the molding material  14  can form the one-piece molding base  1200  on the circuit board jointed panel  1100 , and the one-piece molding base  1200  can form the light window  122  closed all around at the position corresponding to each of the photosensitive elements  13 , so that after cutting the formed one-piece photosensitive assembly jointed panel  1200 , the molding base  12  having the light window  122  is formed on each of the circuit boards  11  and the corresponding photosensitive elements  13  to prevent a part of the molding base from forming an opening similar to that shown in  FIG.  1 C  to communicate the light window  122  to the outside of the molding base  12 . 
     That is, the molding material  14  of the present application can flow forward from the feeding ends  215 A of the two diversion grooves  2151  and  2152  and fill the diversion grooves  2151  and  2152  and the filling groove  2153  of the entire base jointed panel molding guide groove  215 . The molding material  14  can flow from the feed end  215 A to the terminal end  215 B along the two diversion grooves  2151  and  2152  before being cured. And before the viscosity of the molding material  14  reaches a high value and is cured, the molding material  14  can fill the base jointed panel molding guide groove  215 , thereby preventing the connecting wire  15  between the circuit board  11  and the photosensitive elements  13  from being damaged by the molding material  14  having a high viscosity and flowing forward. In addition, through the symmetrical design of the two diversion grooves  2151  and  2152 , the fluid in the two diversion grooves  2151  and  2152  flows substantially at the same step, and the two fluids are converged substantially in the filling groove  2153  to prevent the molding material  14  in a certain diversion groove from flowing to another diversion groove to hinder the molding material  14  in the another diversion groove from flowing forward. Moreover, no turbulence or sinuous flow is generated, the turbulence or sinuous flow would causes the connecting wires  15  connecting the circuit board  11  and the photosensitive element  13  to swing irregularly, resulting in deformation and damage. 
     Accordingly, the molding material  14  of the present application can also be selected from a material with a relatively high viscosity range, thereby avoiding that when a material with a small viscosity range is selected, the molding material  14  easily enters into the photosensitive region  131  of the photosensitive element  13  to form a flash in the molding process. 
     In addition, it is worth mentioning that, as shown in  FIG.  7 B , in order to facilitate demolding and pressing on the rigid region  111  of the circuit board  11 , the first die  211  further includes a plurality of pressing blocks  216 . An outer edge  1201  of the molding base  12  and an outer edge of the rigid region  111  of the circuit board  11  will form a crimping edge  1111 , that is, in the mold process, a region suitable for the pressing block  216  to be pressed onto the rigid region  111  of the circuit board  11 . The pressing block  216  is further pressed over the flexible region  112  of each row of the circuit boards  11  to prevent the molding material  14  from flowing to the flexible region  112 . In addition, the rigid regions  111  of each row of the circuit boards  11  are integrally molded to form an integrated rigid region jointed panel  110 , thereby facilitating the pressing of the first die to each row of the circuit boards  11 . As shown in  FIG.  7 A , on the side adjacent to the flexible region  112 , a width W of a bottom end of the first diversion groove  2151  is 0.2 mm to 1 mm, which is suitable for manufacturing the photosensitive assembly  10  with a small size. Accordingly, the resulting photosensitive assembly  10  has a distance W between an inner edge and a outer edge of the portion  12 A of the molding base on a side adjacent to the flexible region  112  of 0.2 mm to 1 mm. 
     Accordingly, the present application provides a method for manufacturing the photosensitive assembly  12  of the camera module  100 , which includes the following steps: 
     fixing the circuit board jointed panel  1100  to the second die  212  of the molding die  210 , wherein the circuit board jointed panel  1100  includes one or more rows of the circuit boards, and each row of the circuit boards includes one or more circuit board  11  arranged side by side, each of the circuit boards  11  includes a rigid region  111  and a flexible region  112  combined with each other, and each of the circuit boards  11  is operatively connected to the photosensitive element  13 ;

The circuit board  11  and the photosensitive element  13  are connected through a series of connecting wires  15 . After cutting the photosensitive assembly jointed panel  1000 , each of the photosensitive assemblies  10  has a first end side without cutting and a second end side obtained by cutting similarly to the above embodiment.

The inner surfaces  41231  and  41232  of the photosensitive element coupling portion  41211  and the top side extending portion  41212  extend at different slopes, respectively, the second portion inner surface  41232  of the top side extending portion  41212  extends upward with a greater slope with respect to the first portion inner surface  41231  of the photosensitive element coupling portion  41211 , or the second portion inner surface  41232  of the top side extending portion  41212  extends upward without a slope, that is, the second portion inner surface  41232  of the top side extending portion  41212  extends substantially perpendicular to the top surface of the photosensitive element  413 , the top side extending portion  41212  becomes a vertical extending portion, so that the area of the top surface of the top side extending portion  41212  can be relatively large, that is, the top surface of the top side extending portion  41212  determines the area of the top surface  4124  of the molding base  412 , an extension structure of such the photosensitive element coupling portion  41211  and the top side extending portion  41212  can increase the area of the top surface  4124  of the molding base  412 , so that a greater mounting area can be provided for a lens or a lens assembly above the photosensitive assembly  410  to more securely mount the lens or lens assembly above, and can reduce the area of the filter element  414 . 
     That is, in order to facilitate the demolding of the molding process and prevent the stray light, the first portion inner surface  41231  defined by the structure formed by the photosensitive element coupling portion  41211  for its inner surface extends obliquely upward from the photosensitive element  413  with a relatively small slope, and the second portion inner surface  41232  defined by the inner surface of the top side extending portion  41212  extends integrally from the first portion inner surface  41231  in a twisted manner, and extends upward with a relatively large slope or no slope, that is, an included angle is formed between the second portion inner surface  41232  and the first portion inner surface  41231  of the molding base  412 , so that, with respect to the oblique upward extension with a fixed slope, the area of the top surface  4124  of the molding base  412  can be effectively increased. 
     As shown in  FIG.  29 B , an included angle of the first portion inner surface  41231  defined by the inner surface of the photosensitive element coupling portion  41211  relative to the optical axis X of the camera module  400  is α, and an included angle of the second portion inner surface  41232  defined by the inner surface of the top side extending portion  41212  relative to the optical axis X of the camera module  400  is β, wherein the value of α ranges from 3°˜80°, and the value of β ranges from 0°˜10°, and α&gt;β. For example, in a specific embodiment, the value of α is 3°, and the value of β is 0°; in a specific embodiment, the value of α is 30°, and the value of β is 0°; in a specific embodiment, the value of α is 60°, the value of β is 0°; in a specific embodiment, the value of α is 45°, and the value of β is 5°; in a specific embodiment, the value of α is 80°, β The value is 10°. 
     That is, the included angle β of the second portion inner surface  41232  defined by the inner surface of the top side extending portion  41212  relative to the optical axis X of the camera module  400  has a smaller angle with respect to the included angle α of the first portion inner surface  41231  defined by the inner surface of the photosensitive element coupling portion  41211  relative to the optical axis X of the camera module  400 , so that the second portion inner surface  41232  of the top side extending portion  41212  extends upward with a greater slope or in a direction perpendicular to the photosensitive element  413 , thereby increasing the area of the top surface  4124  of the molding base  412 . 
     As shown in  FIG.  29 B , in this preferred embodiment of the present application, preferably, a value of a thickness H 1  of the photosensitive element coupling portion  41211  ranges from 0.05 mm˜0.7 mm, and a value of a thickness H 2  of the top side extending portion  41212  ranges from 0.02 mm˜0.6 mm. For example, in a specific embodiment, the value of the thickness H 1  of the photosensitive element coupling portion  41211  is 0.08 mm, and the value of the thickness H 2  of the top side extending portion  41212  is 0.5 mm; in a specific embodiment, the value of the thickness H 1  of the photosensitive element coupling portion  41211  is 0.4 mm, and the value of the thickness H 2  of the top side extending portion  41212  is 0.3 mm; in a specific embodiment, the value of the thickness H 1  of the photosensitive element coupling portion  41211  is 0.5 mm, the value of the thickness H 2  of the top side extending portion  41212  is 0.1 mm. 
     It can be understood that, the second portion inner surface  41232  of the top side extending portion  41212  turns from the first portion inner surface  41231  and extends in a direction with a smaller angle relative to the optical axis X, so that in the molding process, an indenter pressed onto the photosensitive element  413  can avoid the connecting wire  415  between the circuit board  411  and the photosensitive element  413 , thereby preventing the connecting wire  415  from being crushed. That is, in some cases, if the molding base  412  to be formed extends with a relatively small fixed slope, for example, the angle of the inner surface relative to the optical axis X is 45°˜80°, the indenter pressed on the photosensitive element  413  during the molding process may touch the connecting wire  415  and cause the connecting wire  415  to be damaged. 
     As shown in  FIG.  30   , an included angle α of the first portion inner surface  41231  defined by the inner surface of the photosensitive element coupling portion  41211  relative to the optical axis X of the camera module  400  may be relatively large, so that the light L 12  incident on the first portion inner surface  41231  is not directly reflected to the photosensitive element  413  to form stray light. That is, the photosensitive element coupling portion  41211  and the top side extending portion  41212  cooperate with each other, the structure of the photosensitive element coupling portion  41211  facilitates demolding and reduces the stray light. The top side extending portion  41212  is used to increase the area of the top surface  4124  of the molding base  412 , and such structure of the top side extending portion  41212  prevents the connecting wire  415  from being crushed by the indenter during the molding process. 
     That is, preferably, as shown in  FIG.  29 B , a position  41230  where the first portion inner surface  41231  and the second portion inner surface  41232  are connected is located at inner side of the outer edge  41321  of the photosensitive element  413 , that is, a distance D 1  between the position  41230  where the first portion inner surface  41231  and the second portion inner surface  41232  are connected and the optical axis X is smaller than a distance D 2  between the outer edge  41321  of the non-photosensitive region  4132  of the photosensitive element  413  and the optical axis X, so that the size of the part between the photosensitive element coupling portion  41211  and the photosensitive element  413  is smaller, thereby reducing the possibility that the molding material  416  generates “flash” in the molding process. 
     Further preferably, a position  41230  where the first portion inner surface  41231  and the second portion inner surface  41232  are connected is located at inner side of the connecting wire  415 , and the distance D 1  between the position  41230  where the first portion inner surface  41231  and the second portion inner surface  41232  are connected and the optical axis X is smaller than the distance D 3  between the connecting wire  415  and the optical axis X. A turning point between the photosensitive element coupling portion  41211  and the top side extending portion  41112  does not exceed the position where the connecting wire  415  is located, that is, the photosensitive element coupling portion  41211  completes the transition to the top side extending portion  41112  before it has not yet extended to the position of the connecting line  415 , so as to prevent the connecting wire  415  from being crushed by the indenter during the molding process. For example, when the top side extending portion  41212  is a vertical extending portion, a distance between a position of the inner edge  41241  of the top surface  4124  of the molding base  412  and the optical axis X of the camera module  400  is not smaller than the distance between the connecting wire  415  and the optical axis X of the camera module, so that the top side extending portion  41212  increases the area of the top surface  4124  of the molding base  412  and is integrally embedded the connecting wire  415  without damaging the connecting wire  415 . 
     It can be understood that the inner surface  41231  of the photosensitive element coupling portion  41211  of the molding base  412  extends obliquely to facilitate the demolding operation in the molding process and reduce stray light reaching the photosensitive element  413 , and the inner surface  41232  of the top side extending portion  41212  extends integrally from the inner surface  41231  of the photosensitive element coupling portion  41211  in a twisted manner, so that the photosensitive element coupling portion  41211  and the top side extending portion  41212  cooperate to maximize the area of the top surface of the molding base  412 , in the case of reducing the stray light. 
     In addition, when the filter element  414  is provided with light shielding layer  4142  on the bottom side, as shown in  FIG.  30   , a part of stray light L 11  incident on the top surface of the filter element main body  4141  of the filter element  414  is reflected by the upper surface of the filter element main body  4141  without entering the light window  4122  of the molding base  412 , and when refracting into the surrounding region  41412  outside the light transmitting region  41411  above the light shielding layer  4142 , it will be absorbed by the light shielding layer  4142  and cannot enter the light window  4122  inside the molding base  412 , so as to block a part of the stray light. 
     When another part of stray light L 12  passes through the effective light transmitting region  41411  of the filter element main body  4141  and incidents on the first portion inner surface  41231 , it will be reflected upward to the light shielding layer  4142  by the inclined first portion inner surface  41231  of the molding base  412  or further reflected to light shielding layer  4142  by the second portion inner surface  41232 , so as to be absorbed by light shielding layer  4142 , so as not to be further reflected and reach the photosensitive element  413 , thereby affecting the imaging quality of the camera module  400 . Accordingly, the light shielding layer  4142  is adjacent to the second portion inner surface  41232  of the molding base  412 , and the second portion inner surface  41232  of the molding base  412  extends downward from the light shielding layer  4142 , and a light suppression groove  41221  is formed between the light shielding layer  4142 , the first portion inner surface  41231  and the second portion inner surface  41232 , and on an outer side portion of the light window  4122 , the light suppression groove  41221  is a space for suppressing stray light. More specifically, as shown in  FIG.  30   , the stray light L 12  enters the light suppression groove  41221 , so that it cannot be emitted from the light suppression groove  41221 . 
     It can be understood that, because the light shielding layer  4142  is adjacent to the second portion inner surface  41232  of the molding base  412 , so that the light shielding layer  4142  effectively reduces the light passing through the filter element main body  4141  to the second portion inner surface  41232 , thereby preventing the light incident on the second portion inner surface  41232  from being reflected by the second portion inner surface  41232  and reaching the photosensitive element  413  to form stray light and affect the imaging quality of the camera module  400 . As shown in  FIG.  30   , the second portion inner surface  41232  extends downward from the light shielding layer  4142 , the light shielding layer  4142  extends horizontally from the second portion inner surface  41232 , an included angle γ is formed by the light shielding layers  4142  and the second portion inner surfaces  41232 , and the included angle γ is an acute angle or a right angle, so that the light suppression groove  41221  formed in such a structure prevents the light incident on the inner surface  4123  from being reflected toward the photosensitive element  413  to generates stray light. 
     The filter element  4141  may be mounted on the top surface  4124  of the molding base  412 , such as being adhered to the top surface  4124  of the molding base  412  by glue. The light shielding layer  4142  is a black light absorbing opaque material, and can be formed on the bottom surface of the filter element main body  4141  in various ways, such as being attached to the bottom surface of the filter element main body  4141 , or the light shielding layer  4142  is formed on the bottom surface of the filter element main body  4141  by using a yellow light process or a screen printing process. 
       FIGS.  31 A to  31 C  are schematic diagrams illustrating a manufacturing process of the integrated assembly of the integrated circuit board  411 , the molding base  412 , and the photosensitive element  413  of the photosensitive assembly  410  according to the present application. The manufacturing equipment  4200  includes a molding die  4210 , which includes a first die  4211  and a second die  4212  that is capable of die opening and clamping, that is, a mold fixing device is capable of making the first die  4211  and the second die  4212  being separated and closely contacted to form a molding cavity  4213 . When clamping, the circuit board  411  connected to the photosensitive element  413  is fixed in the molding cavity  4213 , and the fluid-like molding material  416  enters the molding cavity  4213 , so as to be integrally molded on the circuit board  411  and the photosensitive element  413 , and after being cured, the molding base  412  integrally molded on the circuit board  411  and the photosensitive element  413  is formed. It can be understood that, in the production process, the above-mentioned integrated assembly is usually generated in a jointed panel manner, that is, a one-piece molding base is formed on a circuit board jointed panel, then is cut to form the integrated assembly of the present application. In  FIGS.  31 A to  31 C , description is made by using an example to illustrate the formation process of one integrated assembly. 
     More specifically, the molding die  4210  further has a base molding guide groove  4215  and a light window molding portion  4214  located in the base molding guide groove  4215 . When the first die  4211  and the second dies  4212  are clamped, the light window molding portion  4214  and the base molding guide groove  4215  extend in the molding cavity  4213 , and the fluid-like molding material  416  is filled into the base molding guide groove  4215 , and the position corresponding to the light window molding portion  4214  cannot be filled with the fluid-like molding material  416 , so that at the position corresponding to the base molding guide groove  4215 , after being cured, the fluid-like molding material  416  can form the molding base  412 , which includes a ring-shaped molding base main body  4121  corresponding to the molding base  412  of each of the photosensitive assemblies  410 , and the light window  4122  of the molding base  412  is formed at a position corresponding to the light window molding portion  4214 . The molding material  416  may be selected from, but not limited to, nylon, LCP (Liquid Crystal Polymer), PP (Polypropylene), epoxy resin, and the like. 
     More specifically, when the first and second dies  4211  and  4212  are clamped and a molding step is performed, the light window molding portion  4214  is superimposed on the top surface of the photosensitive element  413  and closely adhered, so that the fluid-like molding material  416  is prevented from entering the photosensitive region  4131  of the photosensitive element  413  on the circuit board  411 , so that the light window  4122  of the molding base  412  can be finally formed at a position corresponding to the light window molding portion  4214 . It can be understood that, the light window molding portion  4214  may be a solid structure or a structure having a groove shape inside as shown in the figure. It can be understood that, in another variation, an elastic film  4217  may be further provided on the bottom side of the first die  4211  to provide cushioning and facilitate demolding after the molding process. 
     As shown in  FIGS.  31 A to  31 C , the light window molding portion  4214  is pressed on the photosensitive element  413 , for correspondingly forming the photosensitive element coupling portion  41211  and the top side extending portion  41212  of the molding base  412 , the light window molding portion  4214  has a bottom side molding portion  42141  and a top side molding portion  42142 , the bottom side molding portion  42141  is a frustum shaped structure and has a gradually increasing inner diameter from the bottom side toward the top side. Wherein, An included angle α is formed between the outer surface  421411  of the bottom side molding portion  42141  and the optical axis X (vertical direction shown in the Figure) perpendicular to the photosensitive element  413 , an included angle β is between the outer surface  421421  of the top side molding portion  42142  and the optical axes X perpendicular to the photosensitive elements  413 . Accordingly, the value of α ranges from 3°˜80°, the value of β ranges from 0°˜10°, and α&gt;β. The top side molding portion  42142  extends from the bottom side molding portion  42141  in a twist manner, and it will not be pressed against the connecting wire  415  during the molding process to cause damage to the connecting wire  415 . The outer surface  411411  of the bottom side molding portion  42141  extends obliquely instead of directly forming a sharp right angle, and its height is at least 0.05 mm, so as to prevent the elastic film  4217  from being punctured during the molding process. 
     The light window molding portion  4214  has a first portion outer surface  421411  and a second portion outer surface  421421  in a direction from the bottom side toward the top side, which respectively form angles α and β with the optical axis X perpendicular to the photosensitive element  413 , the value of α ranges from 3°˜80°, the value of β ranges from 0°˜10°, and α&gt;β. Thus, after the molding process, the molding base  412  is formed into the photosensitive element coupling portion  41211  and the top side extending portion  41212 , and the first portion inner surface  41231  defined by the structure formed by the photosensitive element coupling portion  41211  of which is an inner surface thereof extends obliquely upward from the photosensitive element  413  with a relatively small slope, and the second portion inner surface  41232  defined by the inner surface of the top side extending portion  41212  extends integrally from the first portion inner surface  41231  in a twisted manner, and extends upward with a relatively large slope or no slope. That is, the included angle of the first portion inner surface  41231  defined by the inner surface of the photosensitive element coupling portion  41211  relative to the optical axis X of the camera module  400  is α, the included angle of the second partial inner surface  41232  defined by the inner surface of the top side extending portion  41212  relative to the optical axis X of the camera module  400  is β, wherein the value of α ranges from 3°˜80°, and the value of β ranges from 0°˜10°, and α&gt;β. It can be understood that, such structure of the light window molding portion  4214  extending in a twisted manner can reduce the molding material  416  entering the non-photosensitive region  4132  of the photosensitive element  413  and the space  41251  of the bottom side portion of the base molding guide groove  4215  of the first portion outer surface  421411  of the light window molding portion  4214  in the molding process, so that the volume of the molding material  416  in the space is small, and the pressure and pressure force generated are relatively small, so that it is not easy to enter the photosensitive region  4131  of the photosensitive element  413 , that is, avoiding the occurrence of “flash”. 
     In this molding process of the present application, a portion of the bottom side of the base molding guide groove  4215  located between the photosensitive element  413  and the first portion outer surface  421411  of the molding base  412  forms a fill groove  42151 . The molding material  416  that is molded to form the molding base  412  does not easily enter between the photosensitive element  413  and the bottom surface of the light window molding portion  4214  to form a “flash”, thereby reducing the possibility that the photosensitive region  4131  of the photosensitive element  413  is contaminated. More specifically, by reducing the volume of the filling groove  42151  between the photosensitive element  413  and the first portion outer surface  421411  of the light window molding portion  4214 , the pressure and pressure force generated by the material  416  entering the filling groove  42151  is reduced, so that the possibility that the molding material  416  enters between the photosensitive element  413  and the bottom surface of the light window molding portion  4214  to form a “flash” is reduced. 
     In this preferred embodiment of the present application, the outer surface of the light window molding portion  4214  has an outer surface extending in different directions, and the included angle of the top side outer surface of the light window molding portion  4214 , i.e., the second portion outer surface  421421 , relative to the optical axis X of the photosensitive assembly is smaller than the included angle of the outer surface of the bottom side of the light window molding portion  4214 , i.e., the first portion outer surface  421411 , relative to the optical axis X, thereby reducing the volume of the filling groove  42151  formed between the first portion outer surface  421411  of the light window molding portion  4214  and the photosensitive element  413 , thereby reducing the possibility of the occurrence of “flash”. In addition, the second portion outer surface  421421  of the top side of the light window molding portion extends in a direction with a small included angle with the optical axis X, so that unlike the inclined outer surface illustrated in  FIG.  1 B , which is convenient to guide the packaging material into the filling groove, in this embodiment of the present application, the second portion outer surface  421421  of the top side of the light window molding portion can play a certain degree of blocking effect, that is, because it is from the first portion outer surface  421411  extends integrally in a twist manner, not similar to the guide surface structure extending linearly and obliquely in  FIG.  1 B , thereby slowing down the flow rate of the molding material  416  entering the filling groove  42151  to a certain extent, and reducing the pressure force generated when the molding material  416  enters the filling groove  42151 , thereby reducing the possibility of the occurrence of “flash”. Moreover, since the molding material  416  is not easy to form a “flash” in the integral molding process, the light window molding portion  4214  does not need to be pressed onto the photosensitive element  413  with a large pressure, thereby avoiding the photosensitive element  413  is crushed. As shown in  FIG.  32 A , according to a variant embodiment of the third preferred embodiment of the present application, in this embodiment, a top side light shielding layer  4143  is further provided on the top surface of the filter element main body  4141 , so that the top side light shielding layer  4143  and light shielding layer  4142  cooperate to enhance the effect of reducing the stray light. More specifically, the light L 21  incident on the top side light shielding layer  4143  is absorbed by the top side light shielding layer  4143 , and the light L 22  is absorbed by light shielding layer  4142 . It can be understood that, the above third preferred embodiment may also be provided with the top side light shielding layer  4143 . 
     As shown in  FIG.  32 B , according to a variant embodiment of the third preferred embodiment of the present application, the camera module  400  includes the photosensitive assembly  410 , the lens  430 , and a lens supporting element  440 . The lens  430  is assembled on the lens supporting member  440  to form a lens assembly. The lens supporting element  440  may be a fixed lens barrel, thereby forming a fixed focus camera module. 
     Accordingly, the photosensitive assembly  410  includes a circuit board  411 , a molding base  412 , a photosensitive element  413 , and a filter element  414 . The molding base  412  includes a base main body  4121 , which is integrally molded on the circuit board  411  and the photosensitive element  413  and form a light window  4122 . The light window  4122  is a closed space and provides a light path for the photosensitive element  413 . The filter element  414  includes a filter element main body  4141  and a light shielding layer  4142 . The light shielding layer  4142  is a light absorbing opaque material, which is located on the bottom side of the filter element main body  4141  and is located between the filter element main body  4141  and the molding base  412 . 
     Wherein, the molding base  412  has a top side groove  4125  on a top side thereof, and the top side groove  4125  is used for assembling the filter element  414 . That is, in this embodiment of the present application, the top surface  4124  of the molding base  412  may be a multi-step surface, and the top surface  4124  is divided into non-coplanar multi-portion top surfaces, such as a first portion top surface  4124   a  and a second portion top surface  4124   b , the first portion top surface  4124   a  being recessed toward the photosensitive element  413  with respect to the second portion top surface  4124   b , so that a top side groove  4125  is formed on the top side of the first partial top surface  4124   a , and the filter element  414  is assembled on the top side groove  4125 . 
     The top side extending portion  41212  of the molding base  412  is correspondingly two-staged, and the top side groove  4125  is formed on the top side thereof. The inner surface  4123  of the molding base  412  includes the first portion inner surface  41231  of the photosensitive element coupling portion  41211  and the second portion inner surface  41232  and the third portion inner surface  41233  formed by the top side extending portion  41212 , the light shielding layer  4142  is adjacent to the second portion inner surface  41232  of the molding base  412 , and forms The light suppression groove  41221  with the first portion inner surface  41231  and the second portion inner surface  41232 , so that a space for the stray light emission is formed. That is, the light incident on the first portion inner surface  41231  is directly reflected to light shielding layer  4142  or is further reflected to light shielding layer  4142  by the second portion inner surface  41232  to be absorbed by light shielding layer  4142 , thereby reducing the stray light. The top side of the filter element  414  is also provided with the top side light shielding layer  4143  to enhance the effect of eliminating stray light. 
     It can be understood that, in the embodiments shown in  FIGS.  28  to  33   , the wiring direction of the connecting wire  415  is from the photosensitive element  413  to the circuit board  411 , that is, by providing a photosensitive element connecting plate on the photosensitive element  413 , a top end of the photosensitive element connecting plate is wired to form a first end of the connection line  415  connected to the photosensitive element connecting plate, and then a preset position is raised, and then moved toward the circuit board connecting plate on the circuit board and lowered again to form a second end of the connecting wire  415  connected to the circuit board connecting plate at the top end of the circuit board connecting plate. 
     As shown in  FIG.  33   , according to another variant embodiment of the above-mentioned third preferred embodiment of the present application, the electronic components  4112  of the circuit board  411  of the photosensitive assemble  410  of the camera module  400  are mounted on the bottom side of the circuit board, the photosensitive assembly  410  accordingly further includes one or more bottom side molding portions  419 , which integrally embed the electronic component  4112 . That is, the electronic component  4112  is not mounted on the top side of the circuit board  411 , these electronic components  4112  are provided on the bottom side of the circuit board  411 , and by the bottom side molding portion  419 , they can be multiple independent parts, and can also form an integrally molding base, which embed the electronic component  4112  to form a flat support surface on the bottom side. The bottom side molding portion  419  and the molding base  412  may be formed independently, or may be formed in a single molding process. For example, the circuit board  411  may have perforations, and the molding material  416  can reach both sides of the circuit board  411  during the molding process. 
     It can be understood that, the space on the bottom side of the circuit board  411  under the photosensitive element  413  can also be used for arranging the electronic components  4112 , so unlike the above embodiment, the electronic components  4112  need to be arranged around the photosensitive element  413 , in this embodiment, the area of the circuit board  411  is significantly reduced. 
     Accordingly, the molding base  412  includes the photosensitive element coupling portion  41211  and the top side extending portion  41212 , so that when the size of the photosensitive assembly  410  is further reduced, the area of the top surface  4124  of the molding base  412  is increased by the top side extending portion  41212  extending in a twisted manner, so as to provide a greater mounting surface for the lens supporting element  440  and the filter element  414 . In addition, the filter element  414  includes a bottom side light shielding layer  4142  and a top side light shielding layer  4143  provided on both sides of the filter element main body  4141 , thereby enhancing the effect of eliminating the stray light.

That is, by providing a circuit board connecting plate on the circuit board  411 , a top end of the circuit board connecting plate is wired to form a second end of the connection line  415  connected to the circuit board connecting plate, and then a preset position is raised, and then moved toward the circuit board connecting plate and lowered again to form an opposite first end of the connecting wire  415  connected to the photosensitive element connecting plate at the top end of the photosensitive element connecting plate, in this way, the connecting wire  415  extends in a curved shape, and it causes the height h 2  of the top end of the connecting wire  415  to be lower than the height h 1  of the top end of the connecting wire in the embodiments of  FIGS.  28  to  33   , taking  FIG.  33    as an example, so that, in the molding process, a space needed for the light window molding portion  4214  of the molding die  4210  to avoid the connecting wire  415  is reduced, thereby the height of the top side extending portion  41212  can be higher. 
     As shown in  FIGS.  35  to  37   , a camera module  400  according to a fourth preferred embodiment of the present application is shown, wherein the camera module  400  includes a photosensitive assembly  410  and a lens  430 .

     The filter element holder  417  is assembled on the molding base  412  and has an opening window  4171  on the bottom side and a top side mounting groove  4172 , the filter element  414  is assembled on the top side mounting groove  4172 , so that the filter element  414  assembled on the filter element holder  417  is less likely to be damaged than the filter element  412  directly assembled on the molding base  412 . 
     The filter element  414  includes a filter element main body  4141 , a bottom side light shielding layer  4142 , and a top side light shielding layer  4143 , the light shielding layer  4142  is located on the bottom side of the filter element main body  4141  and is located between the filter element main body  4141  and the inner top surface of the filter element holder  417 , the light shielding layer  4142  is a light absorbing material, which makes the filter element main body  4141  form a middle effective light transmitting region  41411  and a surrounding region  41412 , the light passing through the lens  430  can only reach the inside of the molding base  412  through the effective light transmitting region  41411 . The light shielding layer  4142  has a ring structure, and an opening window is formed in the middle, that is, the light shielding layer  4142  forms a light path  41420  for allowing light to enter the light window  4122  and reduce the stray light reaching the photosensitive element  413 , and the top side light shielding layer  4143  can enhance the effect of reducing stray light. 
     The photosensitive element  413  has a photosensitive region  4131  in the middle and a non-photosensitive region  4132  located around the photosensitive region  4131 , the light shielding layer  4142  has an inner edge  41421  and an outer edge  41422 . The distance between the inner edge  41421  of the light shielding layer  4142  and to the optical axis X is greater than or equal to, or slightly smaller than the distance between the outer edge  41311  of the photosensitive region  4131  and the optical axis X. 
     The outer edge  41422  of the light shielding layer  4142  is located outside the inner edge  41701  of the top surface of the filter element holder  417 , that is, no light transmitting region is formed between the inner edge of the top surface of the filter element holder  417  and the outer edges  41422  of the light shielding layer  4142 . 
     In this embodiment of the present application, the base main body  4121  of the molding base  412  includes a plurality of segments of an inner surfaces in a circumferential direction, each of segments of the inner surface has a plurality of the portions extending in different directions, such as the base main body  4121  of the molding base  412  includes three portions, that is, a photosensitive element coupling portion  41211  and a top side extending portion  41212  located around the light window  4122  shown in  FIGS.  36 A and  36 B , and a circuit board coupling portion  41213  on the bottom side of the photosensitive element coupling portion  41211 . The photosensitive element coupling portion  41211  has an inner surface integrally extending from the photosensitive element  413 , and at least a segment of the inner surface integrally extending from the photosensitive element  413  is defined as a first portion inner surface  41231  of the molding base  412 , the top side extending portion  41212  has an inner surface extending integrally from the photosensitive element coupling portion  41211 , and forms a second portion inner surface  41232  of the molding base  412 , the second portion inner surface  41232  is integrally extending from the first portion inner surface  41231 . It can be understood that, each of the first portion inner surfaces  41231  and the second portion inner surfaces  41232  is a certain section of the inner surface of the surrounding inner surface of the base main body  4121 ; or a plurality of sections of the inner surface have the first portion inner surface  41231  and the second portion inner surface  41232  of the same structure; or all of the inner surfaces have the first portion inner surface  41231  and the second portion inner surface  41232 . 
     The inner surfaces  41231  and  41232  of the photosensitive element coupling portion  41211  and the top side extending portion  41212  extend at different slopes, respectively, the second portion inner surface  41232  of the top side extending portion  41212  extends upward with a greater slope with respect to the first portion inner surface  41231  of the photosensitive element coupling portion  41211 , or the second portion inner surface  41232  of the top side extending portion  41212  extends upward without a slope, that is, the second portion inner surface  41232  of the top side extending portion  41212  extends substantially perpendicular to the top surface of the photosensitive element  413 , so that the area of the top surface of the top side extending portion  41212  can be relatively large, that is, the top surface of the top side extending portion  41212  determines the area of the top surface  4124  of the molding base  412 , and such extension structure of the photosensitive element coupling portion  41211  and the top side extending portion  41212  can increase the area of the top surface  4124  of the molding base  412 , so that it can provide a greater mounting area for the lens or the lens assembly or the filter element holder  417  above the photosensitive assembly  410 , for example, in this embodiment, the top surface  4124  of the molding base  412  allows the filter element holder  417  above to be more firmly mounted. And such a structure can reduce the area of the filter element  414 . 
     That is, in order to facilitate the demolding of the molding process and prevent the stray light, the first portion inner surface  41231  defined by the structure formed by the photosensitive element coupling portion  41211  for its inner surface extends obliquely upward from the photosensitive element  413  with a relatively small slope, and the second portion inner surface  41232  defined by the inner surface of the top side extending portion  41212  extends integrally from the first portion inner surface  41231  in a twist manner, and extends upward with a relatively large slope or no slope, that is, an included angle is formed between the second portion inner surface  41232  and the first portion inner surface  41231  of the molding base  412 , so that, in comparison to the oblique upward extension with a fixed slope, the area of the top surface  4124  of the molding base  412  can be effectively increased. It can be understood that, the inner surfaces of the molding base  412  extending in the circumferential direction may all have the above mentioned first portion inner surface  41231  and the above mentioned second portion inner surface  41232 , and the first portion inner surface  41231  may have the same included angle α, or the included angle can be different. These second portion inner surfaces  41232  may have the same angle β, or the included angle can be different. 
     As shown in  FIG.  36 B , an included angle of the first portion inner surface  41231  defined by the inner surface of the photosensitive element coupling portion  41211  relative to the optical axis X of the camera module  400  is α, and an included angle of the second portion inner surface  41232  defined by the inner surface of the top side extending portion  41212  relative to the optical axis X of the camera module  400  is β, wherein the value of α ranges from 3°˜80°, and the value of β ranges from 0°˜10°, and α&gt;β. 
     That is, the included angle β of the second portion inner surface  41232  defined by the inner surface of the top side extending portion  41212  relative to the optical axis X of the camera module  400  has a smaller angle relative to the included angle α of the first portion inner surface  41231  defined by the inner surface of the photosensitive element coupling portion  41211  relative to the optical axis X of the camera module  400 , so that the second portion inner surface  41232  of the top side extending portion  41212  extends upward with a greater slope or in a direction perpendicular to the photosensitive element  413 , thereby increasing the area of the top surface  4124  of the molding base  412  and reducing the area of the filter element, and reducing the possibility of generating “flashing” of the molding material  416  during the molding process. 
     As shown in  FIG.  36 B , in this preferred embodiment of the present application, preferably, the value of the thickness H 1  of the photosensitive element coupling portion  41211  ranges from 0.05 mm˜0.7 mm, and the value of the thickness H 2  of the top side extending portion  41212  ranges from 0.02 mm˜0.6 mm. 
     In addition, the filter element  414  is provided with the light shielding layer  4142  and the top side light shielding layer  4143 , and as shown in  FIG.  37   , a part of the stray light L 31  incidents on the upper surface of the filter element main body  4141  of the filter element  414  is absorbed by the top side light shielding layer  4143 , so as to block a part of the stray light. 
     When another part of the stray light L 32  passes through the effective light transmitting region  41411  of the filter element main body  4141  and incidents on the first portion inner surface  41231 , it will be reflected upward to the light shielding layer  4142  by the inclined first portion inner surface  41231  of the molding base  412  or further reflected to the light shielding layer  4142  by the second portion inner surface  41232 , so as to be absorbed by light shielding layer  4142 , so as not to be further reflected and reach the photosensitive element  413 , thereby affecting the imaging quality of the camera module  400 . Accordingly, the light shielding layer  4142  is adjacent to an inner surface  41702  of the filter element holder  417  located below the filter element, and the inner surface  41702  of the filter element holder  417  located below the filter element extends downward from the light shielding layer  4142 , and a light suppression groove  41221  is formed on the light shielding layer  4142 , on the inner surface  41702  of the filter element holder  417  below the filter element, between the first portion inner surface  41231  and the second portion inner surface  41232 , on the outer side portion of the light window  4122 , and the light suppression groove  41221  is a space for suppressing the emission of the stray light. More specifically, as shown in  FIG.  37   , the stray light L 32  enters the light suppression groove  41221 , so that it cannot be emitted in the light suppression groove  41221 . 
     As shown in  FIG.  38   , according to a variant embodiment of the above mentioned fourth preferred embodiment of the present application, a top side groove  4125  is formed on the top side of the molding base  412 , and the filter element holder  417  is assembled on the top side groove  4125  to move its position downward, and the lens  430  can be assembled on the top side of the molding base  412 . That is, the top surface  4124  enlarged by the molding base  412  by multi-stage extension is used for assembling the filter element holder  417  and the lens  430 . 
     As shown in  FIGS.  39  to  41   , a camera module  400  according to a fifth preferred embodiment of the present application has a structure similar to that of the fourth preferred embodiment. The camera module  400  includes a photosensitive assembly  410  and a lens  430 . The lens  430  is assembled on the photosensitive assembly to form a fixed focus camera module. It can be understood that, in another variant embodiment, the lens may also be provided on a driver or a fixed lens barrel to form a lens assembly, and the lens assembly is assembled on the photosensitive assembly. 
     Accordingly, the photosensitive assembly  410  includes a circuit board  411 , a molding base  412 , a photosensitive element  413 , a filter element  414 , and a filter element holder  417 , the molding base  412  includes a base main body  4121 , which is integrally molded on the circuit board  411  and the photosensitive element  413  and forms a light window  4122 , the light window  4122  is a closed space and provides a light path for the photosensitive element  413 . The molding base  412  includes a photosensitive element coupling portion  41211  and a top side extending portion  41212  located around the light window  4122 , which extends in multi-stage, and the inner surfaces  41231  and  41232  extend in different directions, respectively, so that the stray light is reduced and the area of the top surface  4124  of the molding base  412  is increased. 
     The filter element holder  417  is assembled on the molding base  412 , and has an opening window  4171  on the top side and a bottom side mounting groove  4173 , the filter element  414  is assembled on the bottom side mounting groove  4173  in an inverted manner. The filter element  414  includes a filter element main body  4141  and a light shielding layer  4142 , the light shielding layer  4142  is provided on the bottom side of the filter element main body  4141 . Therefore, similarly, the light shielding layer  4142  can play a role of reducing the stray light reaching the photosensitive element  413 . 
     In addition, the lens  430  includes a supporting member  431  and one or more lenses  432  assembled on the supporting member  431 , wherein, because the filter element  414  is inverted mounted on the filter element holder  417 , so that the filter element  414  does not protrude from the upper surface of the filter element holder  417 , the lens at the bottom of the one or more lenses  432  of the lens  430  can be relatively moved down, so that the distance from the photosensitive element  413  is reduced, thereby reducing the back focus of the camera module  400 . 
     When the filter element  414  is provided with light shielding layer  4142  on the bottom side, as shown in  FIG.  41   , a part of the stray light L 41  incident on the upper surface of the filter element holder  417  is reflected without entering the light window  4122  of the molding base  412 , so as to block a part of the stray light. 
     When another part of the stray light L 42  passes through the effective light transmitting region  41411  of the filter element main body  4141  and is incident on the first portion inner surface  41231 , it will be reflected upward to the light shielding layer  4142  by the inclined first portion inner surface  41231  of the molding base  412  or further reflected to light shielding layer  4142  by the second portion inner surface  41232 , so as to be absorbed by light shielding layer  4142 , so as not to be further reflected and reach the photosensitive element  413 , thereby affecting the imaging quality of the camera module  400 . Accordingly, the light shielding layer  4142  is adjacent to the second portion inner surface  41232  of the molding base  412 , the second portion inner surface  41232  of the molding base  412  is from the light shielding layer  4142  extends downward, and a light suppression groove  41221  is formed on the light shielding layer  4142 , between the first portion inner surface  41231  and the second portion inner surface  41232 , on an outer side portion of the light window  4122 , the light suppression groove  41221  is a space for suppressing the stray light. More specifically, as shown in  FIG.  41   , the stray light L 42  enters the light suppression groove  41221 , so that it cannot be emitted from the light suppression groove  41221 . 
     In addition, it can be understood that, because of the light shielding layer  4142  and the second portion inner surface  41232  of the molding base  412 , the light shielding layer  4142  effectively reduces light passing through the filter element main body  4141  and reaching the second portion inner surface  41232 , thereby preventing the light incident on the second portion inner surface  41232  from being reflected and reaching the photosensitive element  413  to form the stray light and affect the imaging quality of the camera module  400 . 
     As shown in  FIG.  42   , according to another variant embodiment of the fifth embodiment of the present application, the wiring direction of the connecting wire  415  is from the circuit board  411  to the photosensitive element  413 , so that, in the molding process, the light window molding portion  4214  does not need to provide an avoiding space for the connecting wire  415  as much as possible, and the top side extending portion  41212  is made to have a greater height to increase the area of the top surface  4124  of the molding base  412 . 
     In addition, an opening window  4171  is formed on the top side of the filter element holder  417 , and the length of the top side portion  4174  of the filter element holder  417  extending inward may be greater than or equal to the length of the light shielding layer  4142  extending inward, in this way, the area of the opening window  4171  may not be greater than the area of the light path  41420 , so that the top surface of the filter element holder  417  has the effect of blocking a part of the stray light L 51 , so that it is not necessary to provide the top side light shielding layer  4143  on the top side of the filter element  414 . The stray light L 52  can be absorbed by light shielding layer  4142 . 
     As shown in  FIG.  43   , according to another variant embodiment of the fifth embodiment of the present application, the photosensitive assembly  410  includes a circuit board  411 , a molding base  412 , a photosensitive element  413 , and a filter element  414 , a filter element holder  417  and a blocking frame  418 .

The light shielding layer  4142  of the filter element  414  is similar to the above mentioned third preferred embodiment, and is provided on the bottom side of the filter element main body  142  to reduce the stray light. 
     The ring shaped blocking frame  418  is provided on the photosensitive element  413 , and is used to press the light window molding portion  4214  on the blocking frame  418  in a molding process to prevent the fluid-like molding material  416  from flowing into the photosensitive region  4131  of the photosensitive element  413 , wherein the molding base  412  is integrally molded on the circuit board, the photosensitive element  413  and the blocking frame  418 , the blocking frame  418  may be glue in a preferred embodiment, which may have a predetermined elasticity, for example, the elastic modulus ranges from 0.1 Gpa to 1 Gpa.
