How to Avoid Copper Peel Off
Hot Air Solder Leveling (HASL) involves coating the surface of the exposed copper with a layer of tin alloy to prevent oxidation and provide a good soldering surface for subsequent assembly. The basic process of HASL is to briefly immerse the PCB board into a high-temperature liquid tin bath. Through the action of flux and high-temperature tin, a copper-tin alloy (IMG) is formed. Then, on guide rails, the board is lifted out while high-pressure gas blows away excess tin from non-copper areas and level......
