Description

  The present invention relates to a photoelectric signal transmission device including high-speed optical signal transmission, and is particularly suitable for wiring use inside a portable device, which is indispensable for small size, low profile, and surface mounting.

  Conventionally, as an optical transmission apparatus, there is an optical transmission apparatus used for a foldable mobile phone (for example, see Japanese Patent Application Laid-Open No. 2007-267358 (Patent Document 1)). In this cellular phone, high-speed data transmission is performed by optical communication between two cases via an optical fiber cable.

(Receiving side). In addition, the case of a composite device having both transmission and reception performance is also conceivable.

  In any case, in this case, the photoelectric device 2 and the main body substrate are directly connected from the connection terminal of the photoelectric device 2 to the main body substrate by means of reflow or the like, but as the size is reduced, various problems occur. The problems (1) to (5) are presented below.

  (1) When the photoelectric device 2 inserted in the receptacle 1 is tilted, defective mounting on the main body substrate 14 occurs (shown in FIGS. 3A, 3B, and 3C).

  (2) When the height of the photoelectric device 2 is low, the connection terminal 13 of the photoelectric device 2 rises above the side electrode terminal 3 of the receptacle 1, resulting in poor mounting on the main body substrate 14 (FIG. 4A, (Shown in FIG. 4B).

  (3) On the other hand, when the height of the photoelectric device 2 is high, the connection terminal 13 of the photoelectric device 2 is located below the side electrode terminal 3 of the receptacle 1, resulting in poor mounting on the main body substrate 14 (FIG. 5A). , Shown in FIG. 5B).

  (4) In the case of the lead frame type photoelectric device 2, if the variation in the lead height is large, a mounting defect on the main body substrate 14 occurs (shown in FIG. 6).

(5) As the photoelectric device 2 becomes smaller, the area and pitch of the output terminals become narrower, and soldering to the main board 14 becomes difficult (shown in FIGS. 7A and 7B).
