Yes, the photoresist can make or break the gold plating process. Most manufacturers of photoresist make one designed especially for gold, and there are a variety of good products available. The entire process, from preclean prior to resist lamination through gold plating is also critical. All of the posts on this subject have excellent advise. The Hoechst product is, I believe, being sold by Morton as Laminar 5000. Please feel free to contact me directly if I may be of further assistance.
