nickel corrosion

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

Thanks... anyway I confirm, the nickel disappear (verified by cross section)and a strange substance greyish above gold, covering the tabs after test. I don't know the reason for this phenomenon. I don't believe that with proper electrolytic nickel fi

Hi after an enviromental test 85C/85RH, for 3 months (powered), of an electronic assembly with edge finger tabs ENIG finished (nickel 5micron, gold 0.02micron), the nickel disappears completely under the gold (due to corrosion, I think). Does anyone

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

Hi All, I have to solder a device with platinum clad nickel leads to a PCB. I am having a hard time getting solder to flow on to the leads. Are there special proceedures that I need to follow because of the platinum or am I just dealing with contamin

I have a pin and sleeve assembly that utilizes a fusible link type of solder, Bi, Cd, Pb and Sn alloy. The pin is gold plated, the sleeve is copper alloy 725. I have had sporadic success with wetting of the sleeve during the reflow process. To improv

The dissolution rate of nickel into tin is a lot slower than that of copper [into tin]. This results in a nickel-tin (Ni3Sn4) intermetallic that is only 0.25-0.75�m thin after a normal soldering process. The Ni-Sn intermetallic compound tends to be m

One of my customer asking me about my capability on soldering nickel strip onto the PCB pad. Given the size of the pad of 80 mil X 80 mil, and he want to ensure that we can pass 4.5kg peel force(solder wire Sn63/Pb37). Anybody with this experience ?

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
