What Does HASL Stand For?
HASL stands for Hot Air Solder Leveling Electronics
HASL, or Hot Air Solder Leveling, is a surface finishing process used in the electronics manufacturing industry to prepare printed circuit boards (PCBs) for soldering. This technique involves the application of a thin layer of solder to the exposed copper areas of the PCB, which is then leveled using hot air. This process not only enhances the solderability of the boards but also provides protection against oxidation, improving the overall reliability and performance of electronic assemblies. HASL is widely employed due to its cost-effectiveness and proven reliability in various applications.
