PCB Assembly Soldering Circuit Boards Bay Area Circuits HASL Finish is the predominant ‘leaded’ surface finish used in the industry. HASL stands for Hot Air Solder Leveling. The circuit boards must be immersed in a tin lead alloy for this finish. ‘Air knives’ then remove the excess solder by blowing hot air across the surface of the board. How Does Surface Finish Affect Solder Paste Performance ... Lead free HASL is a common finish that has replaced tin lead HASL in many applications. The process used to coat circuit boards with lead free HASL is essentially the same as the process for tin lead HASL. The only exception is the solder alloy that is used.
