ABSTRACT:
A printed wiring board is comprised of a combination of layers providing a good thermal match with surface mount components. The board consists of a core surrounded by multiple layers of dielectric and conductive materials optimized for their thermal expansion qualities. The core is also used as the tooling plate during manufacture. Side-to-side interconnects are made by blind-plated vias and through-holes in the core.
