?t find it in any back issues of Printed Circuit Design or SMT that I have. It is my understanding that our main supplier has the facilities to dry film and is encouraging the dry film solution. (In my opinion more $ and less Competition) Cost is not a big issue since we do not produce large quantities of our products. Any help would be greatly appreciated.
