WHat is the cost difference between double-sided 1-oz FR-4 and Single sided 2OZ CEM-1 Laminate in volume? I used to estimate 1-OZ single sided CEM-1 at $0.07US per square inch in volume. FOB Hong Kong, don't know if that figure is still current. I'm sure I can look these up in DIgikey, but the figures will ahve no relation to production prices. -- Lawrence Lile Sr. Project Engineer Salton inc.
