| 摘要 | PURPOSE:To obtain the proper state of bonding, inhibiting the lowering of productivity by making a wire bonding surface on the lead side run parallel with a wire bonding surface for a light-receiving element. CONSTITUTION:A lead 11 electrically connected to a light-receiving element 7 by a wire 14 is constituted so that a wire bonding surface for the lead 11 is made to run parallel with a wire bonding surface for the light-receiving element 7. The light-receiving element 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 light- receiving element 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 light-receiving element 7. A conical section 15 is molded in a monolithic manner to an umbrella shape at the nose section of the lead 11 electrically connected to the light-receiving element 7, and the apex angle of the conical section 15 is set so that the inclined plane of the conical section 15 is made to run parallel with the inclination of the light-receiving element 7. |
| 其他摘要 | 用途：为了获得适当的粘合状态，通过使引线侧的引线键合表面与用于光接收元件的引线键合表面平行来抑制生产率的降低。组成：通过导线14电连接到光接收元件7的引线11被构造成使得引线11的引线键合表面与光接收元件7的引线键合表面平行。接收从激光芯片5的下端发射的激光束6并监视来自激光束6的光输出的接收元件7固定到诸如杆1的主表面的表面上。光接收元件7被紧固在具有诸如7度的角度的倾斜平面8上。为了防止在光接收元件7的光接收表面上反射光束的盖子2投射到窗口16中，锥形部分15以单片方式模制到杆1的主表面上。引线11的前端部分处的伞形电连接到光接收元件7，并且锥形部分15的顶角设定成使得锥形部分15的倾斜平面平行于倾斜的方向延伸。光接收元件7。 |
