We have been using their PnP-Blue Pres and Peal iron on printed circuit board transfer film for a couple of years and have have found it to be the best method so far (and we have tried a lot of methods ) This is an iron on method where you print the board to their transfer film and iron the film onto the surface of the PC board using an ordinary household iron (if your wife won't let you use 'her' iron you can buy one at the local thrift store for about $5). The result is 2 layers of resist. The film layer and the toner layer. The combination provides a very high degree of resist which will work very well with fine traces and small holes. The hardest part of the whole process is cleaning the toner off the board after it has been etched (which confirms the integrity of the toner as an etchant resist).

They can be reached at www.techniks.com& nbsp; or call them at 908-788-8249

The price we paid was $30 for 20 sheets of 8 1/2 by 11 An excellent deal considering the time and frustration we have saved.
