High cooling efficiency circuit module
摘要:
@ The specification discloses a circuit module (10) having enhanced heat transfer and distribution characteristics which is particularly adapted for use in high speed electronic digital computers. The circuit module (10) includes a circuit board assembly (12) with a plurality of electronic devices (26) such as integrated circuits, mounted on a circuit board (28). The circuit board (28) includes conductive pads (42 and 44) and plated-through holes (46) forming a thermally conductive flow path from each electronic device (26) to the opposite side of the circuit board for more efficient heat transfer away from the module (10). The heat pads (42 and 44) and plated-through holes (46) are preferably connected with the ground plane ■ layer (36) ofthe circuit board (28) for better heat distribution as well.
