Hi, I'm here to ask advice about some special solder alloy. I saw on some Airbag ECU that the the solder alloy remain so shiny for more than 13year. When I say "shiny" I mean shiny like the ball of bearing ball, like a mirror completely smooth and shiny surface. And in this case the pcb was not covered with PCB Lacquer .
So. did you ever find something like this?
Can you tell me if you have some shiny weld in the past and with which product?
