isd.jww: First, the original poster is talking about pads, not component leads. Second, you're correct that chrome plated component leads can be attached by spot welding or crimping a solderable tab to the lead and then soldering the tab to the boa

Thanks for the replies. I haven't soldered to a chrome plated pad in the past and have my doubts so thought I'd ask here. Our customer supplied the material and for some reason decided to change the plating to chrome. We only found out about this

We doubt that you can successfully solder to chrome

How about silver epoxy? Could you use a PnP with a dispenser?

Can you etch where you want to solder to? But you would need harsh chemicals to do that. The whole point of chrome is to not chemically react.

Bare inconel is NOT ment to take solder, because * Nickel develops a tenacious oxide layer that is very difficult to remove since the nature of the oxide is very dense, coherent, etc. * Chromium is difficult to solder. * Iron is difficult to solder.

You can weld (spot) to chrome. Maybe you could weld a nickel tab to the chrome part?

That's not going to work in this case. The substrate has very small pads designed for a micro BGA die. Thanks for the suggestion though.

I have 15 very large backplanes (.156" thick Au plating) that the ground pins of a high density thru-hole connector were not thermal relieved in the artwork. As a result we are unable to solder the 8 pins that connect to the ground plane. We know t

Dear sir, I have a problem to find the new chemical solution instead IPA(isopropyl alcohol) to eliminate contamination on the test pin socket board made from copper that plate with nickle and gold. And after the often testing IC process, the co
