Abstract

A one-hole welding mold for electronic components and a welding process, comprising a welding mold body (1), a plurality of positioning welding molds (2) for placing electronic components on the welding mold body (1), the positioning welding The die (2) consists of a small hole (3) and a countersunk hole (4), the small hole (3) and the countersunk hole (4) pass through, and the centers coincide; the small hole (3) is used to place the lead end of the lower lead (5). , the aperture of the small hole (3) is matched with the lead end of the lower lead (5); the countersunk hole (4) is used to place the head of the lower lead (5), the chip (7) and the upper lead (6), The hole diameter of (4) is matched with the head of the lower lead (5). In the present invention, the upper and lower leads and the semiconductor chip are welded in the same hole, and the welding precision is high, and there is no need to worry about welding dislocation and virtual welding, and the product quality and yield are greatly improved.

Description

technical field [0001] The invention relates to a welding mold for electronic components and a welding process using the mold, in particular to a welding forming process using a single mold, in particular to a one-hole welding mold for electronic components and a welding process. Background technique [0002] Now, the traditional welding process of electronic components (diode, etc.) is the process of welding the upper and lower welding dies. The traditional welding consists of a lead wire on the upper welding die and a lower welding die on each of the upper and lower soldering dies. The aperture is generally about 0.1-0.15mm larger than the diameter of the lead wire. In addition, the upper and lower dies need to be positioned and matched. There is a fit gap during welding, which is prone to welding misalignment and the weld is not tight; at the same time, due to the oxidation of the welding die at high temperature, the aperture As the size increases, it will cause more seri...
