Things don't disappear completely. If something caused nickel corrosion, the nickel corrosion by-product would be in place of the nickel. Is it possible that ... There never was any nickel? We know that the nickel will diffuse into the copper. Th

Your copper corrosion is not good. It indicates that you have not done a good job in cleaning. [We assume this is a medium green color, not unlike the color of the solder mask on your board, that is almost like a translucent lacquer; rather than th

Nichrome, manganin, phosphor bronze etc are easy to solder ... the hard part is removing the corrosion * Manganin: 86% copper, 12% manganese, 2% nickel. Often, it's used in making cryogenic measurements, due to its low heat loss. * Select a flux for

Your plater's recommendation should work fine. Your simple copper plate will work, but you'll be stepping into fighting a copper tarnish battle. Silver over the copper is a better choice. I was thinking a silver thickness of a minimum of 3 microns

Can anybody tell me what kind of anti-seize compound to use in a lead free solder pot? I have found copper, nickel, and silver anti-seize but I cannot decide which one to use. Thanks for the help.

We use copper anti seize on the ball screws in our PBfree reflow ovens.

We don't have Heller, but Vitronics uses copper anti-seize.

davef, thanks for feedback. I talked with a plater who said they put copper before silver when plating brass. Would a complete stack of: Brass part, then 0.0001-0.0002" of copper, then 0.0005" of silver, then Tarniban anti oxidation. Sound reasonabl

Pin holes in the gold can allow for corrosion of the underlying nickel and copper to form copper and nickel oxides on the gold surface (example - http://www.semlab.com/blog/?p=564. The corrosion can work itself all the way through the EN layer (exam
