Hi All,
I understand that the zinc in the brass will migrate into the Sn/Pb
solder and cause defective joints and quite possibly a latent defect.
I've also read that if a solder alloy contains too much zinc it can
produce dull joints and also increase surface oxidation of the molten
metal and possibly affect wetting characteristics of the solder.
My question is: How does the zinc react with the tin and what is the
mechanism that comes into play for joint failure.
Thanks
Scott
