ABSTRACT:
A circuit board assembly for data equipment such as those having large numbers of layers and great power requirements in a small space having high computer performance, includes a multi-layer printed circuit board in laminated technology provided with voltage supply and signal carrying layers and pressure contacts at both sides connecting the multi-layer printed circuit board to further printed circuit boards. The further printed circuit boards, which are formed using micro-wiring technology, include backsides which are free of electrical components and connected to the pressure contacts and opposite sides carrying integrated electrical elements such as circuit chips forming an electrical circuit. Cooling plates are pressed against the surfaces of the circuit chips.
