Solder Paste on Zinc Die Casting
So, the question of the day was will the solder paste solder zinc alloy. Zinc alloy is pretty broad range of materials and so the first answer was – I don’t know. That’s pretty weak so we found a zinc die cast part we use and tested it. This was a Zinc AG40A die cast, unplated zinc material. We tested the solder in some porous sections and between the threads. In both cases the paste did not adhere well to the zinc die cast. We tried again on a nickle plated zinc part and got the same results.

I agree.
We tried some different solder pastes on zinc and none of them gave us a good result.
We had to take some walk around instead.
