Dimensionally stable laminates of epoxy resin reinforced with glass fibers have a coefficient of thermal expansion which matches that of copper, making possible copper foil covered laminates which provide improved registration in multilayer printed circuit boards. New glass fabric styles provide balanced thermal expansion in both the warp and fill directions.
