Q1: What is HASL - Hot Air Solder Leveling?
HASL (Hot Air Solder Leveling) is a metallic surface finishing technique, which is performed on the outermost layer of the PCB board to protect the exposed copper surfaces like tracks until the component placement and soldering is completed.
The HASL coating is composed of Solder with 63% Tin and 37% Lead, and during the assembly process, this coating gets dissolved with the soldering material.
The HASL Coating is applied as per the steps below:
Advantages of HASL:
Limitations of HASL:
