Mira and Andrew, Thank you for the coments. I'm not sure if I've missed out on part of the thread or what, but I'm not certain where the layer registration issues came into play. We got our first cut in and we're fairly certain the copper is right, but the board won't fly. We designed it by relaying it out from legacy bitmap files of the original layer artwork. It was a tremendous undertaking. We have a netlisting tester here (something other than a DITMCO) that substantiated our copper path.
But because copying old "pictures" of layers is an inexact science at best, we now think that we allowed adjacent pads on internal layers that are bigger than on the original, forcing twin traces closer together and thinner than what they are on the original. We are hoping that this combination is responsible for the prob- lems we're experiencing, and that trimming down the unused pads and opening up the area to wider and further apart traces will get us a product we can push out the door. Again, I really appreciate your help with our problems.
