We got a similar alloy Sn05Pb93.5Ag1.5, of Alpha Vaculoy bars. It is not the eutectic alloy you were looking for but it is close. This alloy and similar high temperature alloys are used in downhole electronics and so a supplier in the Houston area

This should be a fun one! I was asked the question from our Engineering, should we use die attach with wire bond or go ahead into the new world of flip chips? Right now, I am faced with information overload about the two processes but I am really l

Hi, I can verify that, and we have done 2 or more reflows with prototypes, using vapor phase reflow, and because there is no oxygen, the result is good, and you cannot tell the difference between the first reflow, and the 3rd. We are getting a vap

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

We are using a Trek board washing system with 2 deionizer tanks hooked up to the 2 final rinse tanks and the first tank is directly connected with the city water. We are having problems with a vendor board on some tranformer/chokes. The part manufact
