Cap for L/D
Semiconductor laser diode sensor is manufactured by mounting L/D chip and PD chip on a flange (also called a stem), and sealed with a metal cap, commonly done by resistance welding. The shape of CAPfs projection is very important, because width, height and diameter of the cap give a large influence to the welding.Furthermore, for stable control of the shape, we measure the dimensions and check the shape according to the cross section of each cap shaped into resin mold.
