摘要

PROBLEM TO BE SOLVED: To enhance the strength of a built-up layer using a simple method. ;SOLUTION: Inner layer plates 4 are overlapped and disposed between resin sheets 8a, 8b with a copper foil via glass crosses 5a, 5b, and these are pinched between stainless plates, and this is inserted into between platens of a multi- stage hot press. Then heating and pressing are conducted, whereby the resinous sheets 8a, 8b with a copper foil are heated and pressured, and built-up layers 9a, 9b reinforced by the glass crosses 5a, 5b are formed on both faces of the inner layer plate 4.;COPYRIGHT: (C)2001,JPO
