Yes, we also never experience erosion phenomenon on our solder pot. We are currently using one Sn Cu based alloy, which is SCS7.

Sorry to interfere with Dave F, but perhaps your IAg finishes have issues with process residues from the boardhouse. What is the base material of your ConAP conformal coating - acrylic, silicone, polyurethane? We do CC (acrylic) and IAg and never h

I believe that leader of industry, Mattel, has a camera that can be obtained at a cost effective level. I believe it is called a BarBie model. And the camera movement can be based on systems from Lionel.

Don't forget rework, post production eco's and other mods. Also if it's on a generic base, how do you spot slight misplacments? Board shops have some fallout, now the fallout with be with the assembly makers and with components trapped on the subst

Hi Davef, Thanks for the reply. There seem to be no issues on SMT reflow based on some samples done. We have not stripped the gold yet. We did a X-section+EDX and we are seeing traces of copper on the nickel layer. Any idea what is the implication of
