METHOD FOR PRODUCING CIRCUIT-FORMING BOARD, CIRCUIT-FORMING BOARD, AND CARBON SHEET

摘要

A method for producing a circuit-forming board by inserting a graphite sheet (1) having a good heat conductivity in the board without electrically connecting the sheet (1) to a conductive hole (6) thereby to prevent the temperature of the heat-generating devices and board from increasing, comprising preparing a heat-dissipating sheet (7) produced by applying resin (2) to a graphite sheet (1), making a sheet hole (3) in the heat-dissipating sheet (7), and fabricating a core (10) by joining an insulating material to the heat-dissipating sheet (7) having the hole (3) by thermocompression bonding.
