HASL PCBs are often labeled as obsolete, yet they are akin to the solder wire found in a master craftsman's toolbox: stable and reliable. I once recommended HASL (Hot Air Solder Leveling) to a client as an alternative to ENIG (Electroless Nickel Immersion Gold); this not only saved costs but also enhanced protective performance. The HASL layer is robust and possesses strong oxidation resistance, performing exceptionally well in extreme environments. For the majority of industrial circuit boards, a 0.8mm pitch is more than sufficient, so there is no need to blindly...
