ABSTRACT:
A printed circuit board is fabricated so contacts for tight-pitch components are at an angle with respect to the bundles of glass fibers in the epoxy-glass printed circuit board such that adjacent component contacts do not contact the same bundle of glass fibers. This angle may be accomplished by manufacturing a printed circuit board panel with the glass fibers at an angle with respect to its edges. This angle may also be accomplished by placing parts on a printed circuit board panel that has a traditional X-Y orthogonal weave of glass fiber bundles at an angle with respect to the edges of the panel. This angle may also be accomplished by starting with a traditional panel that has an X-Y orthogonal weave, laying out parts on the panel along the X-Y weave, then placing components on the parts at an angle with respect to the edges of the parts.
