The advantages of the HASL surface treatment is:
1. The component has a good degree of moisture during soldering and soldering is easier.
2. The exposed copper surface can be protected from corrosion or oxidation.
The defects of the HASL surface treatment is:
1. The flatness on the vertical plane is poor, which does not apply to the welding and use of fine-pitch components. By increasing the level, the flatness can be improved.
2. High thermal stress during processing may damage the PCB board, causing defects or defects.
