WebApr 3, 2024 · When connectors are plated with a very thin “flash” gold deposit (less than 10uin, 0.25um) the gold is a very porous. The gold plating thickness may look continuous but there are thousands of microscopic pores in the deposit making it more like a thin screen of gold rather than a continuous pore-free layer. WebHASL is less environment friendly than ENIG. Choosing ENIG over HASL, reduces the use of lead and emission from flux and fusing oil. HASL might seem cheaper than ENIG for 2 layer boards but as we go for more layers, the cost for ENIG and HASL plating would be very close to each other. HASL has a excellent solder-ability and has a good shelf ... spaghettis cookeo
