Release Date:
[October 14th, 2026: New Bedford, MA] See how the HASL PCB surface finish process works, from equipment preparation and flux application through molten solder coating and hot-air leveling. Hot Air Solder Leveling (HASL) applies solder to exposed copper surfaces on a printed circuit board. As the PCB moves through the process, flux promotes solder wetting, molten solder coats the exposed copper, and hot air removes excess solder to create the finished solderable surface.
