Abstract

PURPOSE:To simplify the manufacture by forming a coating film of a semirigid thermosetting resin on a metal core, thereafter opening a somewhat larger hole at the position of a desired throughhole, stacking a metal foil in alignment with a pin provided in the metal mold, and thereafter heating and pressing this structure, thereby eliminating the need of drilling work. CONSTITUTION:After an aluminium plate 3 is dipped in and uniformly coated with the solution of a phenolsetting epoxy resin, methyl cellosolve, the solvent, is heat-treated to be removed. This aluminium plate is drilled a hole having a large diameter of the order of 1.5mm in the same position as the desired throughhole. Also, after an alumina paper 4 and a copper foil 5 having holes drilled in the same shape as the throughhole are respectively stacked in alignment with a pin 8 along with the aluminium plate, the top force is closed and heating and pressing are performed. This will eliminate the need of forming the throughhole after the laminate molding, enabling the simplification of the manufacture.
