Title: Method of locating SMT connector with SMT cap feature

Abstract:
An improved electronic connector with alignment features is disclosed. One or more alignment features for the connector are disposed on a removable SMT cap that attaches to an external face of the connector. Placing one or more alignment features in the SMT cap may enable fewer alignment features on the device PCB, resulting in increased space for electrical routing and other electrical components.

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates generally to electrical connectors and in particular to electrical connectors that are mounted to a printed circuit board within an electronic device. A wide variety of electronic devices are available for consumers today. Many of these devices have connectors that that facilitate communication with and/or charging of a corresponding device. These connectors often interface with other connectors through cables that are used to connect devices to one another. Sometimes, connectors are used without a cable to directly connect the device to another device, such as a charging station or a sound system. 
     As smart-phones, media players and other electronic devices become more compact, a limiting factor on the size of a particular device may be the size of the printed circuit board (PCB) within the device. Typically, very compact electronic devices may only have one printed circuit board on which one or more connectors along with all the other electronic components and electrical routing are located. As an example, receptacle connectors are sometimes positioned on one or more of the side surfaces of portable media devices and are mounted to a printed circuit board within the device. In relatively small media devices, the receptacle connectors may consume a significant portion of the available space on the PCB, leaving little room for additional electrical routing and other electronic components. 
     Thus, new connectors may require new features and/or changes to commonly used connectors to be able to consume less space on a printed circuit board, leaving more space for other electrical components and electrical routing. 
     BRIEF SUMMARY OF THE INVENTION 
     Embodiments of the invention pertain to technology that is particularly useful in the manufacture of especially compact electronic devices requiring increased PCB space for electrical routing and other electronic components. 
     Some embodiments relate to the formation of electronic connectors that may have an SMT cap attached to an outside face of the electronic connector. The SMT cap may have one or more connector alignment features disposed on a bottom surface that may be used for aligning the connector to the PCB. Further, the SMT cap may sit on a PCB rail that may be removed from the PCB panel prior to installation of the PCB into an electronics device. This may enable fewer connector alignment features to be placed on the portion of the PCB that fits within the electronic device, freeing up PCB space for additional electrical routing or electronic components. 
     Some embodiments of the invention may have one or more alignment features on the SMT cap and one or more alignment features on the rear of the connector. Other embodiments may have two or more alignment features in the SMT cap and no alignment features on the rear of the connector. Further embodiments may not have an SMT cap and may have a portion of the connector body formed into an alignment feature disposed on the front face of the connector. After assembly, this alignment feature may be removed. 
     In some embodiments the alignment features may be cylindrically shaped and fit into corresponding circular apertures in the PCB. In other embodiments, cylindrically shaped alignment features may fit into one or more slotted apertures in the PCB. In further embodiments, one or more of the alignment features may not be cylindrically shaped and may be, for example, in the shape of a blade. 
     Some embodiments of the invention relate to assembling a plurality of connectors with SMT alignment features on a PCB containing a plurality of device PCBs. 
     To better understand the nature and advantages of the present invention, reference should be made to the following description and the accompanying figures. It is to be understood, however, that each of the figures is provided for the purpose of illustration only and is not intended as a definition of the limits of the scope of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Certain embodiments of the present invention relate to electrical connectors assembled to PCBs that may be employed in electronic devices. While the present invention can be useful to produce connector/PCB assemblies for a wide variety of electronic devices, some embodiments of the invention are particularly useful for producing connector/PCB assemblies for electronic devices that require increased room on the PCB for electrical routing or other electronic components, as described in more detail below. 
     Certain embodiments of the present invention relate to electrical connectors employed in electronic devices. Many electronic devices such as smart-phones, media players, and tablet computers have electronic connectors that facilitate battery charging and/or communication with other devices. The connectors include a plurality of electrical contacts through which electrical connections are made to another compatible connector to transfer power and/or data signals through the connectors.  FIG. 1  illustrates an example of two such connectors including a plug connector  110  and a receptacle connector  130 . Each of these connectors  110 ,  130  may comply with a well-known standard such as Universal Serial Bus (USB) 2.0, Firewire, Thunderbolt, or the like or may be proprietary connectors, such as the 30-pin connector used on many Apple products among other types of proprietary connectors. 
     As further shown in  FIG. 1 , plug connector  110  is coupled to a cable  100 , which in turn is coupled to a peripheral device  105  that can be any of many different electronic devices or accessories that operate with such devices. Receptacle connector  130  is incorporated into a computing device  140 . When the plug connector  110  is mated with the receptacle  130 , electrical contacts within each electronic connector (not shown in  FIG. 1 ) are in physical and electrical contact with each other to allow electrical signals to be transferred between computing device  140  and peripheral device  105 . 
     To further illustrate embodiments of the invention, various examples of electrical connectors that include alignment features that may be made in accordance with the present invention are discussed below, however these embodiments should in no way limit the applicability of the invention to other connectors. 
       FIG. 2A  is a simplified perspective view of the bottom surface of an exemplary receptacle connector assembly  200 , in accordance with one embodiment of the invention. Connector assembly  200  may include a connector body  205  that may have a plurality of electrical leads  210  disposed on a rear external face  260 , for mounting to a PCB. A PCB as used herein may be any type of planar structure used to route electrical signals such as, for example, epoxy-glass with metallic traces, low-temperature co-fired ceramic with metallic traces, polyamide layers with metallic traces (flex-PCB&#39;s), or selectively plated plastic. Connector assembly  200  may also have a surface mount technology (SMT) alignment feature  215  protruding from a rear external face  260  of connector body  205  for aligning the connector assembly on a PCB. Connector assembly  200  may further have a removable SMT cap  220  affixed to a front exterior face  265  of connector body  205 . SMT cap  220  may be manufactured from, for example, a plastic such as nylon or liquid crystal polymer. SMT cap  220  may also have an alignment feature  225  protruding from bottom surface  270  of the SMT cap for aligning connector assembly  200  on a PCB. Placing one or more alignment features, like pin  225 , on the SMT cap may save PCB space, as will be illustrated in more detail below. 
     The top side of connector assembly  200  is depicted in  FIG. 2B . In this illustration, SMT cap  220  has been removed from exterior face  265  of connector body  205 . SMT cap  220  may be affixed to the front exterior face  265  of connector body  205  by inserting a latching tongue  235  that includes one or more retention mechanisms  240  (e.g., opposing recesses formed in sides of tongue  235 ) of SMT cap  220  into a receptacle cavity  230  of the connector body. Tongue  235  may be sized and shaped generally the same as a corresponding plug connector that mates with the receptacle connector. Latching retention mechanisms  240  can be adapted to engage with a retention feature, e.g., a spring or detent, within the receptacle connector. Latching tongue  235  can also include one or more cutouts  245  on each side of the tongue to reduce or prevent warpage of the tongue. 
     Connector assembly  200  is shown mounted on a PCB panel  301  in  FIG. 3 . This figure may be representative of one of the many assembly processes for PCB assembly  300 , which will be illustrated in more detail below. A device PCB  305  may be centrally located in PCB panel  301  and may be the portion of PCB panel  301  that can be installed in an exemplary electronic device  140  (see  FIG. 1 ). PCB panel  301  may have one or more PCB rails  315  that may be connected to device PCB  305  by removable tabs  320 . PCB rails  315  may protect device PCB  305  from damage during the manufacturing process, may facilitate handling of the device PCB, and may also contain electrical test coupons to verify the device PCB was manufactured properly. Further, PCB rails  315  may provide mounting support for electronic components such as connector  200 . As shown in  FIG. 3 , electrical leads  210  of connector body  205  may be mounted to device PCB  305 . Connector assembly  200  may be supported on PCB panel  301  by electrical leads  210  and SMT cap  220 . The combination of the electrical leads and the SMT cap may provide the only support for connector body  205 , as PCB panel  301  may be cut away beneath the entire connector body  205 . Further, connector assembly  200  may be aligned to PCB panel  301  using one or more alignment features  215 . One alignment feature  215  is illustrated in  FIG. 3 , and extends from the rear external face  260  (see  FIG. 2A ) of connector body  205  and fits within a corresponding aperture in device PCB  305 . Alignment feature  215  may be used to properly align electrical leads  210  on PCB pads (not shown) on device PCB  305 . 
     A simplified perspective view of the bottom side of PCB assembly  300  is shown in  FIG. 4 . From this view it can be seen that connector assembly  200  may be aligned to PCB panel  301  using two alignment features  215 ,  225 . In some embodiments, connector assemblies may require at least two alignment features to properly locate connector body  205  and electrical leads  210  on device PCB  305 . As illustrated here, alignment features  215 ,  225  may be cylindrical pins that may be disposed in circular apertures in the PCB panel. However, the apertures may be any shape, for example, oval, slotted or square. Alignment feature  225  may extend from bottom surface  270  (see  FIG. 2A ) of SMT cap  220  and be disposed in an aperture in PCB rail  315 , while alignment feature  215  may extend from rear face  260  (see  FIG. 2A ) of connector body  205  and be disposed in an aperture in device PCB  305 . By disposing alignment feature  225  in PCB rail  315 , and not on device PCB  305 , additional space can be used on device PCB for electrical routing and other electronic components. To save even more space on device PCB  305  (see  FIG. 3 ), some embodiments of connector assembly  200  may place more than one alignment feature on SMT cap  220  and no alignment features on connector body  205 . 
     One such embodiment that has alignment features only disposed on SMT cap  520  is connector assembly  500 , depicted in  FIG. 5 . This figure shows a simplified perspective view of the bottom surface of an exemplary receptacle connector assembly  500 . Connector assembly  500  may include a connector body  505  that may have a plurality of electrical leads  510  disposed on a rear external face  560 , for mounting to a PCB. Connector assembly  500  may have a removable SMT cap  520  affixed to a front exterior face  565  of connector body  505 . SMT cap  520  may have two alignment features  515 ,  525  protruding from a bottom surface  570  of the SMT cap for aligning the connector assembly on a PCB. More specifically, both alignment features  515 ,  525  located on SMT cap  520  may be fitted within apertures disposed in PCB rail  315  (see  FIG. 3 ) and no alignment features may be disposed in apertures in device PCB  305 . Because no alignment features are disposed in device PCB  305  (see  FIG. 3 ), this embodiment may save even more space on the device PCB for electrical routing and other electronic components than connector assembly  200 . 
     Many combinations of alignment features may be employed without departing from the invention. More specifically, the number of alignment features on connector body  505  and SMT cap  520  can be varied. Some embodiments may have no alignment features on connector body  505  and all the alignment features on SMT cap  520 , while other embodiments may have one or more alignment features disposed on connector body  505  and one or more features disposed on SMT cap  520 . Other embodiments may have one or more alignment features that are not pins, but are for example, diamond shapes, tapered cylinders, octagons, hexagons, squares and blades. 
     One such embodiment having a non-cylindrical alignment feature is depicted in  FIG. 6 , which shows a simplified perspective view of the bottom surface of an exemplary receptacle connector assembly  600 . Connector assembly  600  may include a connector body  605  that may have a plurality of electrical leads  610  disposed on a rear external face  660 , for mounting to a PCB. Connector assembly  600  may have a removable SMT cap  620  affixed to a front exterior face  665  of connector body  605 . SMT cap  620  may have one SMT alignment feature  625  in the shape of a cylinder, and one SMT alignment feature  615  in the shape of a blade, both protruding from bottom surface  670  of the SMT cap for aligning the connector assembly on a PCB. More specifically, both alignment features  615 ,  625  located on SMT cap  620  may be fitted within apertures in PCB rail  315  (see  FIG. 3 ) and no alignment features may be disposed in apertures in device PCB  305 , saving space on device PCB  305  for electrical routing and other components. Further, because of the rectangular shape of alignment feature  615 , the corresponding aperture in PCB rail  315  may also be generally rectangular in shape, or it may be generally circular in shape. 
     In some embodiments, as depicted in  FIG. 7 , there may not be an SMT cap. This figure shows a simplified perspective view of the bottom surface of an exemplary receptacle connector assembly  700 . Connector assembly  700  may include a connector body  705  that may have a plurality of electrical leads  710  disposed on a rear external face  760 , for mounting to a PCB. Connector body  705  may be comprised of an outer metallic shell  745  wrapped around an interior body  740  that may be substantially comprised of plastic. A front exterior face  765  of connector body  705  may have a receptacle cavity  730  for receiving the plug portion of a mating connector. Connector body  705  may further have alignment features  715 ,  725  for aligning connector assembly  700  on an exemplary PCB panel  301  (see  FIG. 3 ). Alignment features  715 ,  725  may be cylindrical features that may be disposed in circular apertures in PCB panel  301  (see  FIG. 3 ), similar to alignment features depicted in prior embodiments. Here, feature  725  may extend from front exterior face  765  of inner body  740  and may be positioned to be disposed in a corresponding aperture in PCB rail  315  (see  FIG. 3 ). Feature  715  may extend from exterior rear face  760  of connector body  705  and may be positioned to be disposed in a corresponding aperture in device PCB  305  (see  FIG. 3 ). By disposing alignment feature  725  in an aperture on PCB rail  315 , and not on device PCB  305 , additional space can be used on device PCB for electrical routing and other electronic components. 
     In some embodiments, alignment features  715 ,  725  are permanent, and in some embodiments they are removable after connector assembly  700  is attached to device PCB  305  (see  FIG. 3 ). More specifically, in some embodiments, after leads  710  have been attached to device PCB, alignment feature  725  may be removed from inner body  740 . Removal may be performed by simply breaking alignment feature  725  from inner body  740 , or alternative methods may be used such as a cutting operation. In some embodiments, alignment feature  725  may be a part of outer metallic shell  745 . In these embodiments, feature  725  may be, for example, shaped as a blade, or as an extended “V”. In some of these embodiments, alignment feature  725  may be permanent, while in other embodiments the alignment feature may be removed after assembly. In further embodiments, more than one removable alignment feature may be disposed on front face  765  and in some embodiments no alignment features may be disposed on rear face  760 . 
     In some embodiments, multiple exemplary connector assemblies  200 ( 1 ) . . .  200 ( 6 ) may be installed on a single PCB panel  801 , as illustrated in  FIG. 8 . PCB assembly  800  may comprise six connector assemblies  200 ( 1 ) . . .  200 ( 6 ) disposed on a unitary PCB panel  801  during the PCB assembly process. Six device PCBs  805 ( 1 ) . . .  805 ( 6 ) may be centrally located in PCB panel  801  and may be the portions of PCB panel  801  that can be installed in exemplary electronic device  140  (see  FIG. 1 ). Device PCBs  805 ( 1 ) . . .  805 ( 6 ) may each have an electronic component bonding pad area  850  where the leads of connector assemblies  200 ( 1 ) . . .  200 ( 6 ) may be disposed on device PCBs. As depicted in  FIG. 8 , bonding pad area  850  may be disposed on the other side of PCB panel  801  and located adjacent to the aperture in PCB rail  815  for alignment feature  225 . Device PCBs  805 ( 1 ) . . .  805 ( 6 ) may have one or more PCB rails  815  that may be connected to device PCBs by removable tabs  820 . PCB rails  815  may comprise an outer frame around device PCBs  805 ( 1 ) . . .  805 ( 6 ) and may also be disposed between device PCBs spanning from one edge of the frame to the opposite edge of the frame. PCB rails  815  may protect device PCBs from damage during the manufacturing process, may facilitate handling of the device PCB, and may also contain electrical test coupons to verify the device PCB was manufactured properly. Further, PCB rails  815  may provide mounting support for electronic components such as exemplary connector assemblies  200 ( 1 ) . . .  200 ( 6 ). Connector assemblies  200 ( 1 ) . . .  200 ( 6 ) may each be aligned to PCB panel  801  by one or more alignment features  215 ,  225 . For example, feature  215  may extend from connector body  205  (see  FIG. 2A ) and fit within a corresponding aperture in device PCB  805 ( 1 ) . . .  805 ( 6 ). Feature  225  may extend from bottom surface  270  (see  FIG. 2A ) of SMT cap  220  and fit within a corresponding aperture in PCB rail  815 . Alignment features  215 ,  225  of connector assembly  200 ( 1 ) . . .  200 ( 6 ) may be used to properly align electrical leads  210  (see  FIG. 2A ) on PCB pads (not shown) on device PCB  805 ( 1 ) . . .  805 ( 6 ). By disposing alignment feature  225  in an aperture on PCB rail  815 , and not on device PCB  805 ( 1 ) . . .  805 ( 6 ), additional space can be used on device PCB for electrical routing and other electronic components. 
       FIG. 9  illustrates an exemplary simplified process  900  for attaching connectors with alignment features to device PCBs that are subsequently installed in electronic devices, in accordance with embodiments described herein. In step  905  a connector with alignment features is provided. In some embodiments, one or more of the alignment features may be disposed on a removable SMT cap. In other embodiments, one or more of the alignment features may be attached to one or more external faces of the connector body. In step  910 , a PCB panel is provided that may have at least one device PCB and at least one PCB rail disposed on the periphery of the device PCB. In step  915 , the alignment features on the connector may be aligned with corresponding apertures in the PCB panel and the connector can be seated on the PCB panel. In step  920 , the connector may be attached to the device PCB. In some embodiments the connector may have leads that may be soldered to corresponding pads on the device PCB. In other embodiments, the connector may have press-fit pins that may be pressed into corresponding holes in the device PCB. In step  925 , the PCB rails may be removed from the device PCB. In some embodiments this may comprise removing tabs that connect the PCB rails to the device PCB. This may be accomplished with, for example, a punching operation, a laser operation, a sawing operation, or a breaking operation. In step  930 , if an SMT cap was installed on the connector, it may now be removed, leaving only the connector attached to the device PCB. In step  935  the device PCB may now be installed in the electronic device. 
     In the foregoing specification, embodiments of the invention have been described with reference to numerous specific details that may vary from implementation to implementation. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense. The sole and exclusive indicator of the scope of the invention, and what is intended by the applicants to be the scope of the invention, is the literal and equivalent scope of the set of claims that issue from this application, in the specific form in which such claims issue, including any subsequent correction.
