ENIG is pretty standard these days and cheap in high volumes. A few cents more per board (the plating is super thin) is offset by more reliable soldering of parts like BGAs due to the superior flatness compared to cheaper HASL.
- snops 8y agoAgreed, and there are very few accelerometers/gyros available in packages that don't require ENIG for reliability as the market is driven by phone usage, it would almost definitely cost more to get an (obscure/old) accel than just use ENIG. I agree with the rest of OPs points though, all the seperate LED boards are a bit excessive.
- dfox 8y agoIn many board houses Pb-free HASL costs the same as ENIG. And many board houses will try hard to convince you, that OSP is good thing (my experience is that it is not and it is total PITA, unless the board is only wave soldered) and you don't need any plating at all and if you do, ENIG is the cheapest variant.
