Abstract:
1. A method for manufacturing a semiconductor laser module that assembles a carrier on a thermoelectric device and the thermoelectric device on a base, the carrier mounting a laser diode thereon, the method comprising: disposing a first solder with a first melting point between the base and a lower plate of the thermoelectric device; disposing a second solder with a second melting point lower than the first melting point between the carrier and an upper plate of the thermoelectric device; heating the base, the thermoelectric device and the carrier to melt the first solder and the second solder at the same time by a heater disposed beneath the base to assemble the carrier on the thermoelectric device and to assemble the thermoelectric device on the base; and cooling the first and second solders, the thermoelectric device and the carrier on the thermoelectric device to room temperature, wherein heating the base, the thermoelectric device and the carrier is performed within 60 seconds from about 200° C. to about 280° C. for the temperature of the base, and wherein the cooling is performed within 20 seconds from about 280° C. to about 200° C. for the temperature of the base.
