HASL is the predominant surface finish used in the industry. The process consists of immersing circuit boards in a molten pot of a tin/lead alloy and then removing the excess solder by using 'air knives', which blow hot air across the surface of the board.
One of the unintended benefits of the HASL process is that it will expose the Printed Circuit Board to temperatures up to 265°C which will identify any potential decontamination issues well before any expensive components are attached to the board.
