摘要 | PURPOSE:To obtain the proper state of bonding, inhibiting the lowering of productivity by making a wire bonding surface formed by the nose surface of a lead run parallel with a wire bonding surface for a photodetector. CONSTITUTION:The nose surface of a lead 11 with which a wire 14 electrically connected to a photodetector 7 is bonded is made to run parallel with a wire bonding surface for the light-receiving element 7. The photodetector 7 receiving laser beams 6 emitted from the lower end of a laser chip 5 and monitoring an optical output from laser beams 6 is fixed to a surface such as the main surface of a stem The photodetector 7 is fastened to an inclined plane 8 having an angle such as 7 deg. to the main surface of the stem 1 in order to prevent projection into a window 16 for a cap 2 of reflected beams on the light-receiving surface of the photodetector 7 of laser beams 6. An inclined plane section 15 is molded in a monolithic manner at the nose section of the lead 11 electrically connected to the photodetector 7, and the apex angle of the inclined plane section 15 is set so that the inclined plane of the inclined plane section 15 is made to run parallel with the inclination of the photodetector 7. |
其他摘要 | 目的:为了获得适当的粘合状态,通过使引线的鼻表面形成的引线键合表面与光电探测器的引线键合表面平行来抑制生产率的降低。组成:与光电探测器7电连接的导线14与其连接的引线11的鼻表面与光接收元件7的引线键合表面平行。光电探测器7接收从光发射器7发射的激光束6。激光器芯片5的下端和监视来自激光束6的光输出固定到诸如杆1的主表面的表面上。光电探测器7固定到具有诸如7度的角度的倾斜平面8上。为了防止在激光束6的光检测器7的光接收表面上的反射光束的盖子2投射到窗口16中,在一个方向上模制倾斜的平面部分15。在与光电探测器7电连接的引线11的前端部分处,设置倾斜平面部分15的顶角,使得倾斜平面部分15的倾斜平面与光电探测器7的倾斜平行。 。 |
