Problems solved by technology

[0003] 1) The welding process is carried out in the air, rich in more oxygen, more oxygen will remain in the weld, prone to stress tendencies, and then easily lead to cracks in the solder;
[0004] 2) Every time an electronic component is welded, the solder joint needs to be preheated, and the welding efficiency is low

Abstract

The invention discloses a welding device and method for an electronic component, and relates to the technical field of electronic component welding. The adopted welding method adopts the designed unique electronic component welding device, the welding time is shortened, the reliable structure of a welding spot part can be ensured, and the electronic component and the corresponding pattern of the PCB can be fully and correctly connected. In the welding process of the electronic component, a vacuum environment is created, oxygen does not exist in a welding seam, the stress tendency is not prone to occurring, and welding flux is not prone to generating cracks. In the preheating process, the whole PCB is preheated at a time, due to the fact that the PCB is in the vacuum environment, the PCB can keep the preheating temperature for a long time, and the preheating time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of electronic component welding, in particular to a welding device and method for electronic components. Background technique [0002] Soldering has traditionally been widely used as a method of mounting electronic components on PCBs. At present, the items required for manual soldering of electronic components include solder and electric soldering iron. In order to avoid unfavorable situations such as false soldering, the electric soldering iron is often first touched to the spot to be soldered for about 2 seconds, and then the solder is sent to the spot to be soldered. The current manual soldering method for electronic components has the following defects: [0003] 1) The welding process is carried out in the air, rich in more oxygen, more oxygen will remain in the weld, prone to stress tendencies, and then easily lead to cracks in the solder; [0004] 2) Every time an electronic component is welded, it i...
