HASL

HASL Equipment

Hot Air Solder Leveling (HASL) equipment is used in PCB manufacturing to coat the board’s exposed copper surfaces with a thin, even layer of solder. In this process, the PCB is dipped into molten solder, and high-pressure hot air removes the excess, creating a smooth, flat surface ideal for component mounting. HASL equipment helps improve PCB durability and oxidation resistance, providing a reliable, solderable finish that extends the lifespan of the PCB. This equipment is commonly used across electronics, automotive, telecommunications, and LED industries where dependable PCB quality is essential.
