WebHot Air Solder Leveling is a popular surface finish used on printed circuit boards with a long successful history. To create the HASL finish, the printed circuit board will be submersed in molten solder (tin / lead). This … WebHASL makes component soldering very effective, but due to the thickness of HASL coating, the planarity of the surface may be unsuitable for fine-pitch components. The HASL deposit is made from a eutectic blend of …
WebApr 7, 2024 · HASL finishes are created by dipping the board into a tin and lead or tin and nickel solder and holding it there for some time. Once the PCB is removed, hot bursts of air called air knives remove the excess finish. HASL finishing allows for a large processing window, but various factors can affect its evenness and therefore its solderability. WebHASL or HAL (for hot air (solder) leveling) is a type of finish used on printed circuit boards (PCBs).. The PCB is typically dipped into a bath of molten solder so that all exposed copper surfaces are covered by solder. Excess solder is removed by passing the PCB between hot air knives.. HASL can be applied with or without lead (Pb), but only lead …
