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

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

I assume that you're talking about wanting to solder to metal tabs that are spot welded to the battery terminal. These tabs are not meant to be soldered. The metal was special selected for welding. In the old days, you could buy plumbing flux at th

Congratulations on your new customer. This could be a keeper. Here's what you're familiar with: Electroless Nickel - per MIL-C-26074 and ASTM-B733. Electroless nickel describes the plating of nickel deposits, which may contain phosphorus and boro

Electroless Nickel without gold immersion

Has anybody expierianced solderability issues on electroless nickel boards that do not have gold immersion? We recently tried to process boards of this type, and I may as well have been trying to reflow on plastic. Any ideas?

It could be that you're starting with hyper corroded nickel, before you even begin work. With electroless nickel, everybody looks at the nickel, but the cause turns out to be the immersion gold is too aggressive [during fabrication]. Immersion gold

5uin. Your nickel thickness is fine. Although if you wanted to trade costs, consider giving-up nickel to 150uin thickness, while increasing the gold thickness. Gold over electroless nickel creates brittle joints because of phosphorous in the nicke
