Manufactured by heating and pressurizing a stack of press plates in a laminated press. ing. In International Publication No. 8502969, copper is electrodeposited on a press plate. A similar method of this type has been described. Conventionally known laminating presses are heated This is a hydraulic press with a lower platen that applies heat to the top and bottom surfaces of the stack of materials to be stacked. and pressure can be applied. This results in lateral forces during the lamination process that cause the resin to tends to be pushed out.

The pressure applied presses the thermally conductive portion against the stack, transferring heat and pressure to the stack. to communicate. a plurality of grooves on the inner surface of one or more thermally conductive portions; can be provided. Such grooves guide gases and vapors during lid evacuation useful for. The thermally conductive part is substantially rigid (compared to the deformable part) However, it should have a slight degree of flexibility sufficient to adhere tightly to the surface of the stack.

ガス圧は支持底板2および蓋1によって構成された包囲容器によって積重体の全 ての面に伝達される。ガスの熱はアルミニウム製の支持底板2、側板8および頂 板12によって積重体の全ての面に迅速かつ実質的に均一に伝達される。 ′加 熱中に包囲容器内に拡がるガスまたは蒸気はオートクレーブの外側にある真空源 に接続された真空管路によって弁16を経て排気される。The gas pressure is distributed throughout the stack by the enclosure constituted by the supporting base plate 2 and the lid 1. transmitted to all surfaces. The heat of the gas is transferred to the aluminum support base plate 2, side plates 8 and top plate. The plate 12 provides rapid and substantially uniform transmission to all sides of the stack. ′加 The gas or vapor that spreads into the enclosure during heating is removed by a vacuum source outside the autoclave. It is evacuated via valve 16 by a vacuum line connected to .
上述した方法によれば、熱が迅速かつ一様に浸透し、したがって積重体内部の熱 平衡が迅速に達成される。したがって、広範囲の樹脂硬化条件(時間、温度)に 対応させることができる。積層に有害な閉じ込められた空気の除去は容易に行わ れる。According to the method described above, the heat penetrates quickly and uniformly, thus reducing the heat inside the stack. Equilibrium is quickly achieved. Therefore, it can withstand a wide range of resin curing conditions (time, temperature). It can be made to correspond. Easily removes trapped air that is harmful to the laminate It will be done.
