A HASL PCB board is a printed circuit board that uses the Hot Air Solder Leveling (HASL) process as its surface finish. This process involves coating the exposed copper pads of a PCB with molten solder and then leveling the surface with hot air knives. The result is a uniform, protective solder layer that enhances solderability and protects the copper from oxidation. HASL PCB boards are among the most widely used types in electronics manufacturing because the process is cost-effective, provides a long shelf life, and ensures strong solder joints. This makes them suitable for both prototyping and mass production.…
