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 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

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

Hello, We are facing solderability issues on a particular lot of board. THe Nickel thickness measured with an XRF is around 400 U inches. Spec calls out for 130 u inches Nickel and 3 - 5 U inches gold over it. Assuming there is no porosity on the g

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

Are we possibly talking palladium instead of platinum? I haven't yet heard of platinum terminations (seems expensive) If it is palladium over nickel, I can tell you that you need to reach 225-230 Deg. C in reflow and the TAL should be about 90 sec.

Poor reflow over gold plating

When discussing this with the customer he said that his vendor recommended a hard gold plating finish on the board due to the BGA. I said "hard gold"??? And he said yes, hard gold. Turns out the boards were plated with hard gold, not ENIG. Thank

If the gold fingers are pad types which plug into expansion slot connectors, I have used a titanium guard attached to the wave conveyor over the solder pot, which allows the PCB to connect to the fingers but masks the solder from the gold pads along
