Thanks. I have another question. I believe this machine was originally set up to run nitrogen. In the cooling section there are two chambers. One with a radiator air/nitrogen knives and the other section/chamber has a blower. Instead of running nitr

Fine magnet wire responds well to abrasion stripping. Here's one I've used: http://www.carpentermfg.com/magnet.htm Teflon requires a different kind of stripper called a twin blade rotary stripper or a precision die stripper because it's subject to

We like to use "enameled wire" that can be stripped by hot solder. Formvar [105�C] will not do that. Formvar was designed to with stand the hot oil seen in transformers. So, it requires either chemical or mechanical stripping. Most polyurethanes

Intermetallic compounds [IMC]: * Form during the alloying process of some metals. In soldering these are Sn, Ni, Ag, Cu, Au. * Do not accept solder. * Increase in depth in logarithmic proportion to both time and temperature. [So during the solder

This is a problem of contamination in the plating bath. Most prominent with white tin and some gold over nickel plating processes. Rather than argue with your vendor over the issue, and to avoid future recurring problems, I use either HASL or elect
