I am shopping for a fine magnet/manganin wire stripper. Something to strip a variety of coatings from Formavar to Teflon off of 30awg and up wires. Something easy to use and set up. Anyone got one they can recommend? Thanks coeps

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 cold-flow. Carpenter makes that too. They will test your samples and recommend the right stripper for your application at no cost. Make sure you let them know you heard about them on SMTnet.

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 and nylon coatings are in thermal classes of 105�C, 130�C, 155�C and 180�C which should be removable while immersed in molten solder. The dwell time will be significantly longer than what is used to tin temperature sensitive components.

Consider asking the person that specified this insulation to choose a more manufacturing friendly material.

I have designed a tool that works great on magnet wires. I am in the process of applying for patent. The tool will work on ml coated magnet wires (36-45 AWG).

If you are intersted, please send an email to mkhosh@bellsouth.net.
