His company has recieved the materials that they needed, and are quite satisfied. Hopefully the NEC regional rep will get a fire lit under them (that was the level that the problem was at). Now on with the story: I've wire-wrapped a few things in the past. Now I need to make some PC boards for things which are not suited for wire-wrapping due to mechanical considerations (e.g., a "daughterboard" that sits in place of an IC chip & adds various functionality). I have a good idea of what's required for making PC boards, i.e. that you have a photoresist, a mylar transparency, and an ultraviolet light, and you do it all in a darkroom then dip it into etchant. What I don't have is the specifics -- the specific methodology, the chemicals used, where to buy supplies, etc. Is there a "how-to" sort of book for etching PC boards? Have any of the major electronics magazines published articles on how to do it? (I can fetch such articles off of microfilm at the library, though it'll be expensive). (a sad day, eh, when a software guy takes up a slaughtering iron? :-) -- | // Eric Lee Green P.O.
