Patent Description:
In recent years, as the technology industries thrive, electronic devices, such as personal computer (PC), tablet PC, notebook computer (NB), and smart phone, have become very common in our daily life. Electronic devices are developed into diverse forms and have more and more functions, and the convenience and practicability brought by the electronic devices make them become more and more popular. Such electronic devices may be equipped with electronic components as required and the electronic components may be disposed on a circuit board or connected through a flexible printed circuit board for the electronic devices to perform corresponding functions.

Take a controller with sensing components as an example, the sensing components may be disposed on the flexible printed circuit board and then disposed on a supporting holder to be assembled into the controller. Accordingly, the controller is able to detect a signal sent by a signal source through the sensing components (to sense an infrared ray emitted by the signal source through an infrared sensor, for example) so as to generate a corresponding control signal. The sensing components may also be other types of electronic components to enable the controller to execute corresponding operations. Thus, according to the configuration of the electronic components and the structural design of the supporting holder, the controller may use a plurality of strip flexible printed circuit boards to carry the electronic components in multiple directions of the supporting holder. However, tolerances may easily occur in the assembly of the flexible printed circuit boards in the controller, and the assembly process is relatively complicated.

The document <CIT> shows a molded interconnect device that can carry a Hall sensor for transducing a position of a rotor of the implantable blood pump. The molded interconnect device includes one or more integrated electronic circuit traces configured to electrically connect the hall sensor with a printed circuit board of the implantable blood pump, and the molded interconnect device is configured to be mounted to the printed circuit board.

The document <CIT> relates to a device for acquiring predetermined state variables inside a room, in particular in the interior of a motor vehicle, with at least one temperature sensor an with a humidity sensor, hat least regions of which are enclosed by a housing, wherein a first temperature sensor exhibits at least one contact surface for abutting against a perimeter surface bordering the room, and that at least one second temperature sensor is provided inside the housing for acquiring the room temperature. The contact surface is thereby a surface piece of a printed circuit board section of a printed circuit board, which encompasses elastic characteristics,
wherein the printed circuit board section encompasses a plurality of surface pieces, which are angled relative to one another, and the temperature sensors are arranged at different surface pieces.

In accordance with the present invention a controller as set forth in the independent claim is provided.

To make the aforementioned and other features and advantages of the disclosure more comprehensible, several embodiments accompanied with drawings are described in detail as follows.

The drawings illustrate exemplary embodiments of the disclosure and, together with the description, serve to explain the principles of the disclosure.

<FIG> is a schematic top view of a flexible printed circuit board according to an illustrative example not part of the invention. <FIG> is a schematic top view of the flexible printed circuit board of <FIG> with electronic components thereon. Referring to <FIG>, a flexible printed circuit board <NUM> includes an annular main board <NUM> and a plurality of branches <NUM>. The branches <NUM> are connected with and surround the annular main board <NUM>. Each of the branches <NUM> includes an extension portion <NUM> and a bonding portion <NUM>. The extension portion <NUM> connects the bonding portion <NUM> with the annular main board <NUM>. Accordingly, the flexible printed circuit board <NUM> is adapted for a controller <NUM> (as shown in the figures described below), wherein an electronic component <NUM> required by the controller <NUM> is disposed on the bonding portion <NUM> (as shown in <FIG>) and the flexible printed circuit board <NUM> is further connected with the electronic parts in the controller <NUM>. Nevertheless, the flexible printed circuit board <NUM> of the application is not necessarily applied to the controller and may also be used in other electronic devices.

Specifically, the annular main board <NUM> of the flexible printed circuit board <NUM> has a substantially annular shape. The branches <NUM> surround the annular main board <NUM> and are integrally connected with a lateral side of the annular main board <NUM>, and it may be deemed that the branches <NUM> are formed by extending from the lateral side of the annular main board <NUM>. Each of the branches <NUM> includes the extension portion <NUM> and the bonding portion <NUM>, wherein the extension portion <NUM> extends from the lateral side of the annular main board <NUM> and the bonding portion <NUM> is connected with the corresponding extension portion <NUM> and is located at an end of the branch <NUM>. The number of the branches <NUM> in this embodiment is eleven, for example, wherein two of the branches <NUM> extend toward a center of the annular main board <NUM> from an inner side of the annular main board <NUM> while the other nine of the branches <NUM> extend outward from an outer side of the annular main board <NUM>. Therefore, the flexible printed circuit board <NUM> includes eleven bonding portions <NUM>. Nevertheless, it should be noted that the application is not intended to limit the number and locations of the branches <NUM>/the bonding portions <NUM>, which may be adjusted as required.

Moreover, the flexible printed circuit board <NUM> further includes a connection portion <NUM> and connection lines (not shown). The connection portion <NUM> is connected with the annular main board <NUM> and is located between two adjacent branches <NUM>. The connection lines are disposed on the annular main board <NUM> and the branches <NUM> and extend from the connection portion <NUM> to the bonding portion <NUM> of each of the branches <NUM>. Thereby, the electronic component <NUM> is disposed on the bonding portion <NUM> of each of the branches <NUM> in a proper manner (fixed on a conductive pad on the bonding portion <NUM> via a conductive adhesive or solder, for example) to be electrically connected with the connection lines on the corresponding branch <NUM>. Preferably, a width W1 of each of the bonding portions <NUM> is greater than a width W2 of the corresponding extension portion <NUM>, so as to facilitate disposing the electronic component <NUM> on each bonding portion <NUM>, and the extension portion <NUM> may be reduced in size as long as it is sufficient for disposing the corresponding connection lines, such that the assembly of the branch <NUM> is more flexible for further application. Moreover, in order to increase the structural strength of the bonding portion <NUM>, a reinforcement plate may be disposed on a back surface (opposite to the surface where the electronic component is disposed) of the bonding portion <NUM>.

Thus, when the flexible printed circuit board <NUM> with the electronic component <NUM> thereon is further applied to the controller <NUM> (as shown in the figures described below), the flexible printed circuit board <NUM> is suitable to be connected with the electronic parts in the controller <NUM> via the connection portion <NUM>, such that the electronic component <NUM> required by the controller <NUM> is electrically connected with the electronic parts in the controller <NUM> via the connection lines on the corresponding branch <NUM> and the connection portion <NUM>. Based on the design described above, the flexible printed circuit board <NUM> of this embodiment obtains multiple bonding portions <NUM> with an annular distribution without need of connecting manner and therefore the assembly process is relatively simple.

<FIG> is a schematic perspective view of a supporting holder used in an embodiment of the invention. <FIG> is a schematic top view of the supporting holder of <FIG>. Referring to <FIG>, a supporting holder <NUM> includes an annular base <NUM>, two wing structures 220a and 220b, and a plurality of mounting portions <NUM>. The wing structures 220a and 220b extend outward from the annular base <NUM>. The mounting portions <NUM> are disposed on the annular base <NUM> and the wing structures 220a and 220b. Accordingly, the supporting holder <NUM> is adapted for supporting the flexible printed circuit board <NUM> in the controller <NUM> (as shown in the figures described below). However, the application is not intended to limit the flexible printed circuit board supported by the supporting holder <NUM> and the application thereof. That is, the supporting holder <NUM> may also be used to support other flexible printed circuit boards or other electronic parts, and may also be used in other electronic parts.

Specifically, the annular base <NUM> of the supporting holder <NUM> has a substantially annular shape. The wing structures 220a and 220b are connected integrally with a lateral side of the annular base <NUM> and extend outward from the annular base <NUM>. The mounting portions <NUM> are disposed on the annular base <NUM> and the wing structures 220a and 220b. The number of the mounting portions <NUM> is eleven, for example, wherein two of the mounting portions <NUM> are located on the annular base <NUM> close to an inner side of the annular base <NUM>, seven are located on the annular base <NUM> close to an outer side of the annular base <NUM>, and two are respectively located on the wing structures 220a and 220b. Nevertheless, the application is not intended to limit the number and locations of the mounting portions <NUM>, which may be adjusted as required. Thus, the annular base <NUM> and the wing structures 220a and 220b all have the mounting portions <NUM> thereon.

Moreover, the wing structures 220a and 220b have an angle θ (as shown in <FIG>) therebetween, and each of the wing structures 220a and 220b respectively tilts and extends toward a side of the annular base <NUM> to form a tilt angle α (as shown in <FIG>) with respect to a horizontal reference plane H where the annular base <NUM> is located. The angle θ refers to an angle between extending directions D1 and D2 of the wing structures 220a and 220b when the supporting holder <NUM> is viewed from above (as shown in <FIG>), and the tilt angle α refers to an angle of the extending directions D1 and D2 of the wing structures 220a and 220b with respect to the horizontal reference plane H where the annular base <NUM> is located when the supporting holder <NUM> is in a horizontal state. The angle θ is <NUM> degrees, for example, and the wing structures 220a and 220b tilt and extend toward the same side of the annular base <NUM> and preferably have the same tilt angle α, such that the wing structures 220a and 220b are symmetrically located on two opposite sides of the the annular base <NUM>. Nevertheless, the application is not limited thereto and the configuration may be adjusted as required.

In addition, each mounting portion <NUM> further has a positioning structure <NUM>. The positioning structure <NUM> protrudes from the mounting portion <NUM> and extends in two directions to restrict the corresponding bonding portion <NUM>. Specifically, the positioning structure <NUM> is an L-shaped rib that extends in two directions and protrudes from two adjacent lateral sides of the mounting portion <NUM>, for example. Therefore, when the flexible printed circuit board <NUM> is disposed on the supporting holder <NUM>, the bonding portion <NUM> is restricted by the positioning structure <NUM> in two directions to be disposed at a fixed position on the mounting portion <NUM>. That is, two adjacent lateral sides of the bonding portion <NUM> may be restricted by the L-shaped positioning structure <NUM> to be disposed on the mounting portion <NUM> easily. It is known from the above that the design of the positioning structure <NUM> helps to position the bonding portion <NUM> on the mounting portion <NUM>. Nevertheless, the application is not intended to limit the type of the positioning structure <NUM> or whether the positioning structure <NUM> is disposed, which may be adjusted as required.

Thus, when the supporting holder <NUM> is further applied to the controller <NUM> (as shown in the figures described below), the supporting holder <NUM> is suitable for supporting the aforementioned flexible printed circuit board <NUM> (as shown in <FIG>) to be assembled to other electronic parts (not shown), so as to fix the flexible printed circuit board <NUM> in the controller <NUM>. More specifically, when the flexible printed circuit board <NUM> is disposed on the supporting holder <NUM>, the annular main board <NUM> and the branches <NUM> of the flexible printed circuit board <NUM> are located on the annular base <NUM> and the wing structures 220a and 220b, and the bonding portion <NUM> of each of the branches <NUM> is located on the corresponding mounting portion <NUM>. Based on the design described above, the supporting holder <NUM> increases the configuration range of the mounting portions <NUM> through the wing structures 220a and 220b, which also increases the number and configuration range of the bonding portions <NUM> of the flexible printed circuit board <NUM> and the electronic components <NUM> on the bonding portions <NUM> (as shown in <FIG>) and thereby improves the operational efficiency of the controller <NUM> (as shown in the figures described below) using the supporting holder <NUM>.

<FIG> is a schematic exploded view of a controller according to an embodiment of the invention. <FIG> is a schematic view of assembly of the controller of <FIG>. <FIG> is a partially enlarged view of the controller of <FIG>. <FIG> is a schematic perspective view of the controller of <FIG>. Referring to <FIG>, in this embodiment, the controller <NUM> includes two flexible printed circuit boards <NUM> and <NUM> and two supporting holders <NUM> and <NUM>. The flexible printed circuit boards <NUM> and <NUM> are disposed on the supporting holders <NUM> and <NUM> correspondingly, and the supporting holders <NUM> and <NUM> are assembled to each other. However, in other embodiments not shown here, the number of the flexible printed circuit boards and the supporting holders may be one or more, and the flexible printed circuit boards and the supporting holders correspond to each other. Nevertheless, the application does not exclude the possibility of using one single supporting holder to support multiple flexible printed circuit boards, which may be adjusted as required.

Specifically, regarding this embodiment, the structural features of the flexible printed circuit board <NUM> and the supporting holder <NUM> have been specified above and thus are not repeated hereinafter. The flexible printed circuit board <NUM> is disposed on the supporting holder <NUM>, wherein the annular main board <NUM> is disposed on the annular base <NUM> and the branches <NUM> are disposed on the annular base <NUM> and the wing structures 220a and 220b, such that the bonding portions <NUM> are located on the mounting portions <NUM> correspondingly. Furthermore, the annular base <NUM> has a top surface S1 and a bottom surface S2 opposite to each other, and the mounting portions <NUM> are located on the top surface S1 of the annular base <NUM> and the wing structures 220a and 220b. The annular main board <NUM> of the flexible printed circuit board <NUM> is disposed on the bottom surface S2 of the annular base <NUM>, and the branches <NUM> extend to the top surface S1 of the annular base <NUM> and the wing structures 220a and 220b through the corresponding extension portions <NUM>, such that the bonding portion <NUM> of each of the branches <NUM> is located on the mounting portion <NUM> correspondingly, as shown in the upper parts of <FIG> and <FIG>. Accordingly, the bonding portions <NUM> with the electronic components <NUM> thereon are disposed on the mounting portions <NUM> and have an annular distribution on the annular base <NUM> and the wing structures 220a and 220b of the supporting holder <NUM>. However, in other embodiments not shown here, the flexible printed circuit board <NUM> may also be disposed on the top surface S1 of the annular base <NUM>. Nevertheless, the application is not limited to the embodiment described above.

Furthermore, in this embodiment, the flexible printed circuit board <NUM> and the supporting holder <NUM> have similar structural features. Specifically, the flexible printed circuit board <NUM> includes an annular main board <NUM>, a plurality of branches 320a and 320b, a connection portion <NUM>, and connection lines (not shown). The supporting holder <NUM> includes an annular base <NUM>, two wing structures 420a and 420b, and a plurality of mounting portions <NUM>. The structural features of the annular main board <NUM>, the branches 320a and 320b, the connection portion <NUM>, and the connection lines have been specified in the descriptions of the annular main board <NUM>, the branches <NUM>, the connection portion <NUM>, and the connection lines. Moreover, the structural features of the annular base <NUM>, the wing structures 420a and 420b, and the mounting portions <NUM> have been specified in the descriptions of the annular base <NUM>, the wing structures 220a and 220b, and the mounting portions <NUM>. Thus, descriptions of similar parts are not repeated hereinafter.

In this embodiment, a main difference between the flexible printed circuit board <NUM> and the aforementioned flexible printed circuit board <NUM> is that the number of the branches 320a and 320b of the flexible printed circuit board <NUM> is different from the number of the branches <NUM> of the aforementioned flexible printed circuit board <NUM>, and the branch 320b has different structural features from the branches <NUM> and 320a. Specifically, in this embodiment, the number of the branches 320a and 320b of the flexible printed circuit board <NUM> is nine, for example. Three branches 320a extend toward a center of the annular main board <NUM> from an inner side of the annular main board <NUM> and include an extension portion 322a and a bonding portion 324a. Likewise, the other four branches 320a extend outward from an outer side of the annular main board <NUM> and include the extension portion 322a and the bonding portion 324a. In addition, the extension portion 322a and the bonding portion 324a also have the structural design of the aforementioned extension portion <NUM> and the bonding portion <NUM> (for example, the width W1 of each of the bonding portions <NUM> is greater than the width W2 of the corresponding extension portion <NUM>). In contrast, two branches 320b extend outward from the outer side of the annular main board <NUM> and include an extension portion 322b and three bonding portions 324b, wherein the bonding portions 324b are disposed on three adjacent lateral sides of the extension portion 322b, and a width of the extension portion 322b is greater than a width of each of the corresponding bonding portions 324b. The above design is made such that the bonding portions <NUM>, 324a, and 324b of the flexible printed circuit boards <NUM> and <NUM> are staggered and not in contact with one another after being assembled. Nevertheless, the application is not intended to limit the number and locations of the branches 320a and 320b, which may be adjusted as required.

Accordingly, in this embodiment, the flexible printed circuit board <NUM> includes thirteen bonding portions 324a and 324b, and the electronic components <NUM> may be disposed on the bonding portions 324a and 324b of the branches 320a and 320b in a proper manner to be electrically connected with the connection lines on the corresponding branches 320a and 320b. When the flexible printed circuit board <NUM> with the electronic components <NUM> thereon is further used in the controller <NUM>, the flexible printed circuit board <NUM> is suitable to be connected with the electronic parts in the controller <NUM> via the connection portion <NUM>, such that the electronic components <NUM> required by the controller <NUM> are electrically connected with the electronic parts in the controller <NUM> via the connection lines on the corresponding branches 320a and 320b and the connection portion <NUM>. Based on the design described above, the flexible printed circuit board <NUM> used in this embodiment obtains the multiple bonding portions 324a and 324b with an annular distribution without need of connecting manner and therefore the assembly process is relatively simple.

On the other hand, a main difference between the supporting holder <NUM> and the aforementioned supporting holder <NUM> is that, in accordance with the structural design of the branch 320b of the flexible printed circuit board <NUM>, the wing structures 420a and 420b include a plurality of mounting portions <NUM> correspondingly. Specifically, the number of the mounting portions <NUM> in this embodiment is thirteen, for example, wherein three mounting portions <NUM> are located on the annular base <NUM> close to the inner side of the annular base <NUM>, four mounting portions <NUM> are located on the annular base <NUM> close to the outer side of the annular base <NUM>, and six mounting portions <NUM> are respectively located on three adjacent lateral surfaces of the two wing structures 420a and 420b (that is, each of the wing structures 420a and 420b corresponds to three mounting portions <NUM>). However, the application is not intended to limit the number and locations of the mounting portions <NUM>, which may be adjusted as required. Thus, the annular base <NUM> and the wing structures 420a and 420b all have the mounting portions <NUM> thereon.

Furthermore, in this embodiment, the wing structures 420a and 420b may also have technical features similar to the angle θ and the tilt angle α (as shown in <FIG>) of the aforementioned wing structures 220a and 220b. Preferably, an angle between the wing structures 420a and 420b is the same as the angle θ between the wing structures 220a and 220b, and a tilt angle of each of the wing structures 420a and 420b is the same as the tilt angle α of each of the wing structures 220a and 220b, such that the wing structures 420a and 420b and the wing structures 220a and 220b are suitable to be stacked and assembled. In addition, each of the mounting portions <NUM> may have a positioning structure (e.g. the L-shaped positioning structure <NUM> aforementioned). Nevertheless, the application is not intended to limit the type of the positioning structure or whether the positioning structure is disposed. Accordingly, the supporting holder <NUM> is suitable for supporting the flexible printed circuit board <NUM> and being assembled to other electronic parts not shown here, so as to fix the flexible printed circuit board <NUM> in the controller <NUM>, wherein the annular main board <NUM> and the branches 320a and 320b of the flexible printed circuit board <NUM> are located on the annular base <NUM> and the wing structures 420a and 420b, and the bonding portions 324a and 324b of the branches 320a and 320b are located on the mounting portions <NUM> correspondingly.

Furthermore, in this embodiment, the annular base <NUM> has a top surface S3 and a bottom surface S4 opposite to each other, and the mounting portions <NUM> are located on the bottom surface S4 of the annular base <NUM> and the wing structures 420a and 420b. The annular main board <NUM> of the flexible printed circuit board <NUM> is disposed on the top surface S3 of the annular base <NUM>, and the branches 320a and 320b extend to the bottom surface S4 of the annular base <NUM> and the wing structures 420a and 420b through the corresponding extension portions 322a and 322b, such that the bonding portions 324a and 324b of the branches 320a and 320b are located on the mounting portions <NUM> correspondingly, as shown in the lower parts of <FIG> and <FIG>. Accordingly, the bonding portions 324a and 324b with the electronic components <NUM> thereon are disposed on the mounting portions <NUM> and have an annular distribution on the annular base <NUM> and the wing structures 420a and 420b of the supporting holder <NUM>. However, in other embodiments not shown here, the flexible printed circuit board <NUM> may also be disposed on the bottom surface S4 of the annular base <NUM>. Nevertheless, the application is not limited to the embodiment described above. Based on the design described above, the supporting holder <NUM> of this embodiment increases the configuration range of the mounting portions <NUM> through the wing structures 420a and 420b, which also increases the number and configuration range of the bonding portions 324a and 324b of the flexible printed circuit board <NUM> and the electronic components <NUM> on the bonding portions 324a and 324b and thereby improves the operational efficiency of the controller <NUM> (as shown in the figures described below) using the supporting holder <NUM>.

Referring to <FIG>, a method of assembling the controller <NUM> includes respectively disposing the flexible printed circuit boards <NUM> and <NUM> on the corresponding supporting holders <NUM> and <NUM>, for example, by fixing the flexible printed circuit boards <NUM> and <NUM> onto the corresponding supporting holders <NUM> and <NUM> by an adhesive (not shown), so as to form the upper and lower parts (as shown in <FIG>). The annular main boards <NUM> and <NUM> of the flexible printed circuit boards <NUM> and <NUM> are located on the bottom surface S2 of the annular base <NUM> and the top surface S3 of the annular base <NUM> correspondingly to be sandwiched between the supporting holders <NUM> and <NUM>, and the branches <NUM>, 320a, and 320b are located on the top surface S1 of the annular base <NUM> and the bottom surface S4 of the annular base <NUM> to be fixed on the outer sides of the supporting holders <NUM> and <NUM>. Thus, the flexible printed circuit boards <NUM> and <NUM> are fixed between the supporting holders <NUM> and <NUM> and the electronic components <NUM> and <NUM> disposed on the branches <NUM>, 320a, and 320b are located on the outer sides of the supporting holders <NUM> and <NUM> and do not overlap one another.

Moreover, referring to <FIG>, in this embodiment, the flexible printed circuit board <NUM> further includes a plurality of positioning structures <NUM> located on a periphery of the annular main board <NUM>, which are positioning holes on the inner side or the outer side of the annular main board <NUM> for example, and the supporting holder <NUM> further includes a plurality of positioning structures <NUM> located on a periphery of the annular base <NUM>, which are positioning pillars on the inner side or the outer side of the annular base <NUM> for example. The positioning structures <NUM> of the flexible printed circuit board <NUM> correspond to the positioning structures <NUM> of the supporting holder <NUM>, so as to position the flexible printed circuit board <NUM> on the supporting holder <NUM>. Likewise, the flexible printed circuit board <NUM> and the supporting holder <NUM> may also have similar positioning structures. Nevertheless, the application is not intended to limit the type of the positioning structure or whether the positioning structure is disposed, which may be adjusted as required. Then, the supporting holders <NUM> and <NUM> that respectively support the flexible printed circuit boards <NUM> and <NUM> are assembled together by engagement, locking, or other suitable means. At the moment, the electronic components <NUM> and <NUM> respectively on the bonding portions <NUM>, 324a, and 324b have an annular distribution and are not in contact with one another.

Furthermore, in this embodiment, since the design of the wing structures 220a, 220b, 420a, and 420b may increase the number and configuration range of the bonding portions <NUM>, 324a, and 324b and the electronic components <NUM> and <NUM>, the angle θ between the wing structures 220a and 220b, the angle between the wing structures 420a and 420b, the tilt angle α of each of the wing structures 220a and 220b, and the tilt angle of each of the wing structures 420a and 420b may affect the operational efficiency of the controller <NUM> as well. The angle θ between the wing structures 220a and 220b (as shown in <FIG>) and the angle between the wing structures 420a and 420b are preferably <NUM> degrees, but may be any angle (e.g. <NUM>, <NUM>, or <NUM> degrees) in a range of <NUM>-<NUM> degrees. Likewise, the tilt angle α of each of the wing structures 220a and 220b (as shown in <FIG>) and the tilt angle α of each of the wing structures 420a and 420b may be any angle in a range of <NUM>-<NUM> degrees, and preferably in a range of <NUM>-<NUM> degrees. In this embodiment, the tilt angle α is <NUM> degrees. Nevertheless, the application is not limited thereto and the configuration may be adjusted as required.

In this embodiment, the electronic components <NUM> and <NUM> are infrared sensors, for example. The infrared sensors serving as the electronic components <NUM> and <NUM> are disposed on the bonding portions <NUM>, 324a, and 324b correspondingly and are located on the mounting portions <NUM> and <NUM> and have an annular distribution, such that the electronic components <NUM> and <NUM> are able to sense signal sources (for example, to receive infrared rays emitted by the signal sources) in a range of <NUM> degrees, so as to determine relative positions of the controller <NUM> and the signal sources in the space.

In this embodiment, the flexible printed circuit boards <NUM> and <NUM> obtain multiple bonding portions <NUM>, 324a, and 324b with an annular distribution without need of connecting manner and therefore the assembly process is relatively simple. Moreover, the supporting holders <NUM> and <NUM> increase the configuration range of the mounting portions <NUM> and <NUM> through the wing structures 220a, 220b, 420a, and 420b, so as to increase the number and configuration range of the bonding portions <NUM>, 324a, and 324b of the flexible printed circuit boards <NUM> and <NUM> and the electronic components <NUM> and <NUM> on the bonding portions <NUM>, 324a, and 324b. Accordingly, in addition to sensing signals in the range of <NUM> degrees by the electronic components <NUM> and <NUM> that have an annular distribution on the annular bases <NUM> and <NUM>, the controller <NUM> also enhance the sensing efficiency by the electronic component <NUM> on the wing structures 220a, 220b, 420a, and 420b. Consequently, the operational efficiency of the controller <NUM> is improved. In other embodiments, the electronic components <NUM> and <NUM> may be other types of sensors or electronic components, and the electronic components <NUM> and <NUM> may be the same or different to enable the controller to perform corresponding operations/functions. Nevertheless, the application is not limited thereto.

To conclude the above, in the controller of the application, the flexible printed circuit board includes the annular main board and the branches while the supporting holder includes the annular base, two wing structures, and multiple mounting portions located on the annular base and the wing structures. Therefore, when the flexible printed circuit board and the supporting holder are assembled to form the controller, the annular main board is disposed on the annular base and the branches are disposed on the annular base and the wing structures, such that the bonding portions of the branches and the electronic components on the bonding portions are located on the mounting portions correspondingly. Accordingly, the electronic components have an annular distribution on the flexible printed circuit board and the supporting holder and are further distributed onto the wing structures. Moreover, according to the number and configuration/locations of the electronic components required by the controller, the number of the flexible printed circuit boards and the number of the supporting holders may be more than one as required, and preferably the electronic components on multiple flexible printed circuit boards do not overlap one another after assembly. Accordingly, the flexible printed circuit board of the application obtains multiple bonding portions with an annular distribution without need of connecting manner and the assembly process is relatively simple. Moreover, the supporting holder of the application increases the configuration range of the mounting portions through the wing structures, so as to increase the number and configuration range of the bonding portions of the flexible printed circuit board and the electronic components on the bonding portions and thereby improve the operational efficiency of the controller of the application.
