What Are the Different Types of PCB Surface Finishes?
A final step in the PCB fabrication process, the decision to use a specific finish type is often driven by cost, electrical properties, durability, and other factors. Common PCB finishes include HASL (hot air solder leveling), OSP (organic solderability preservatives), and ENIG (electroless nickel immersion gold). When selecting a surface finish, it’s essential to consider...
