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 a heat sink for drawing excess heat from the components. An integral thermal interface region is used to dissipate the heat from the core.
