Description

Technical Field

[0001] The invention belongs to the technical field of circuit board component welding, and in particular relates to a tin plug plate structure for welding anti-collision of copper end component pins of a circuit board. Background Art

[0002] Wave soldering is to make the soldering surface of the plug-in board directly contact with high-temperature liquid tin to achieve the purpose of soldering. The high-temperature liquid tin maintains an inclined surface, and a special device is used to make the liquid tin form a wave-like phenomenon, so it is called "wave soldering". Its main material is solder bar.

[0003] The wave soldering process involves inserting components into the corresponding component holes on the circuit board, pre-applying flux, soldering the component pins into the component holes, waiting for the wave soldering to cool, cutting off the excess plug-in pins, and finally checking whether the soldering is normal.

[0004] Copper terminal parts are welded on the existing circuit board, and the pins of the copper terminal parts are inserted into the plug-in holes. The pins of the copper terminal parts are welded to the plug-in holes by soldering wire, and a gap is formed between the copper terminal parts and the circuit board. When welding components that are close to the sides of the copper terminal parts, the components are prone to tin rushing during welding, causing the solder to be blocked to the bottom of the copper terminal parts, thereby making the entire circuit board scrapped and unusable. Summary of the invention

[0005] The purpose of the present invention is to propose a tin-blocking plate structure for welding pins of copper-end parts of circuit boards to solve the problem of gaps being formed between existing copper-end parts and circuit boards, which may easily cause tin rushing and clogging in the gaps when welding components around the copper-end parts, resulting in the entire circuit board being scrapped.
