Zinc from the brass [Cu3Zn2] diffuses into the tin causing solderability problems. Just 0.001% of Zn in your solder can render it fit for the scrap heap. So, you need a barrier plate between the brass and the tin. Copper or nickel-plating is commonl

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 customer's question is reasonable. Soldering to nickel is not always a walk on the beach [can of corn, or whatever]. This issue is flux not solder. Your Sn63 will have plenty of strength, providing the solder connection is well formed. You s

We agree with Russ that you're talking palladium instead of platinum. Your wetting problem likely is not the Pd-Ag surface layers, but the underlying metal or nickel to which you need to wet. Either a base metal is: * Contaminated and poorly wettabl
