Description

Technical Field

[0001] This utility model relates to the field of welding equipment, specifically a circuit board pin welding device. Background Technology

[0002] A circuit board, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board. During production, the metal leads of electronic components need to be soldered onto the circuit board using circuit board processing and soldering equipment. Therefore, the circuit board needs to be fixed during soldering. The soldering fixtures used in traditional circuit board soldering equipment have simple structures. During the soldering process, due to external forces, the circuit board and the fixture are prone to loosening, resulting in deviations in the soldering position of the leads and seriously affecting the subsequent soldering effect.
