H.A.S.L. Hot Air Solder Leveling
 
This process allows us to apply solder to the circuit boards after they have been screened. Thus allowing them to be wave soldered without the lifting of the solder masks. The boards are fluxed then dipped into a large vertical solder tank. After which the excess solder is blown off with high temperature compressed air knives. This process produces a flat solder finish suitable for surface mount components.

Hot Air Solder Leveling produces one of the most stable end finishes with very good long term solder-ability. With time the base track copper migrates into the solder layer, hand soldering is almost unaffected but machine soldering becomes unreliable. 

With a thin pure tin finish might might expect a  solder-ability of weeks, with pure silver its a few months, but with HASL its more usually a few years.
