A kind of soldering method of electronic component pins

Abstract

The invention provides an electronic component pin brazing method. The method finishes pin brazing operation of a piezoresistor through cooperation of a pressure bearing platform, a fixation clamp anda welding gun and the like, and solves the problems that when brazing is carried out between the piezoresistor and the circuit board, it is usually necessary to manually insert pins of the piezoresistor into welding holes of a circuit board, hold the piezoresistor, and then, fill brazing fillers around the welding holes and carry out welding through the welding gun, wherein in the process of direct manual operation of the piezoresistor, it is easy to cause bending contact of the two pins of the piezoresistor, which affects brazing, and meanwhile, in the process of heating and melting the brazing fillers, the piezoresistor needs to be held by hands to prevent deviation of the piezoresistor, and manually holding the piezoresistor for heating can cause shaking of the piezoresistor easily, which affects the brazing effect and is easy to cause danger to the hands and the like.

Description

technical field [0001] The invention relates to the technical field of soldering, in particular to a soldering method for pins of electronic components. Background technique [0002] Brazing refers to a welding method in which the solder below the melting point of the weldment and the weldment are heated to the melting temperature of the solder at the same time, and the gap between the solid workpiece is filled with liquid solder to connect the metal; the contact surface of the base metal must be removed first during brazing Oxide film and oil on the surface, so that the capillary can play a role after the solder is melted, and increase the wettability and capillary fluidity of the solder. Among them, according to the different melting points of the solder, brazing is divided into hard brazing and soft brazing.

AI Technical Summary

Problems solved by technology

[0003] When brazing the varistor and the circuit board, it is usually necessary to manually insert the pins of the varistor into the welding hole of the circuit board, hold the varistor, and then fill the soldering hole around the welding hole. The material is welded by a welding torch. In the process of manual direct operation of the varistor, the two pins of the varistor are likely to be bent and contacted, which affects brazing. At the same time, the varistor needs to be supported during the process of heating and melting the solder. Prevent the deflection of the varistor; manually holding the varistor for heating may easily cause the varistor to shake, affect the brazing effect, and easily cause danger to the hands
