Comparison of PCB Surface Finish

As we all know, copper is easily oxidized when exposed in the air, which is not good for welding with the electronics components. Therefore, we need to protect the PCB copper by cladding a special film. And we will compare 4 different surface finish as below to make you understand more clearly:
Surface Finish Advantage Disadvantage
OSP Good welding Performance; Smooth Surface; RoHS; Cheap Short-time Storage
HASL(Hot Air Solder Leveling) Good welding Performance; Long-time storage; Cheap Unsmooth Surface; not RoHS compliance
Lead Free HASL Long-time storage; RoHS Unsmooth Surface; a little expensive
ENIG(Immersion Gold) Good welding Performance; Smooth Surface; RoHS Expensive
