Abstract:
Printed circuit board (PCB) substrates include at least one pre-preg layer interposed between one or more electrically conductive layers, power device stacks, each having a power device embedded within the PCB substrate in a vertical stack configuration, and a flat heat pipe positioned between the power device stacks within the at least one pre-preg layer, one surface of the flat heat pipe directly bonded to a first one of the power device stacks and an opposite surface of the flat heat pipe thermally coupled to a second one of the power device stacks.
