There is a misunderstanding that people think the IMC layer grows the thicker the stronger soldering strength. The IMC layer can be grown and distributed evenly at the interface location will be good enough. Once the IMC layer grows too thick and ove

I have seen a similar problem once about 15 yrs ago. Someone decided to try a water wash flux for tinning wires. Bad idea! The wires were dipped in the flux, then in a solder pot. As the lead tin's it forces the flux in the strands to move up the wir
