常用的无线电、立体声设备、电视、复印机、汽车等,在很多方面都需要焊锡。锡焊在电子设备中是不可缺少的。在焊锡作业中,电烙铁必须接通电源。实际上,熔解焊锡,进行焊锡作业的时间非常短。因此,作业以外的准备时间只要用很少的电力使烙铁头保温即可。 Commonly used radio, stereo equipment, television, copiers, cars, etc., in many ways need to solder. Soldering in electronic equipment is indispensable. In soldering work, the electric iron must be switched on. In fact, it takes very little time to solder and solder. Therefore, preparation time other than work can be as long as the thermal insulation of the tip with very little power.
