ABSTRACT:
An electrical wire has a central electrically conductive member such as copper, aluminum, gold or silver or admixtures or alloys thereof, coated by a photoresistive insulator, preferably of a negative photoresistive material such as polyimide. A non-mechanical method of stripping a desired portion of the length of the insulator from the electrical wire comprises exposing the desired length of the electrical wire to a source of UV light. The UV light then “softens” the insulator which either evaporates or can be dissolved by immersing it in a solvent.
