Is one coat too thick? I tried it with 1 coat, 2 coats, and even 3 coats. the one with the 3 coats seemed to work best. Even on the instructions it suggests that more that one coat works better. One thing strange... The color of the PRE-sensitized boards were a different color than the one I sensitized. Does that have any factor???? > For one-offs, why not use Stahler mills (which I've hyped on this > newsgroup before) and spare yourself all the etching hassle ? What is Stahler mills???? I've never heard of that before... Could you please explain. The only way I know of making a PC board without etching it is wire wrapping or using copper stick on's. Neighbor
