本発明は、そり特性の優れた積層板の製造方法に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a laminate with excellent warpage characteristics.

仮内中央部に圧力が集中し、そりが大きい欠点があり、
特性向上の点からも積層条件の検討が行なわれてきた。Conventionally, in the production of laminates, a bushing material (kraft paper, rubber material, organic fiber material, inorganic material, etc. (single item or composite material), at high temperature 60 ~
We have been using a method of molding by applying a pressure of 150 kg/J to cause resin flow. However, due to the large amount of resin flowing, there is a large plate thickness deviation (difference in plate thickness between the center and the edges), which causes pressure to concentrate at the center of the temporary inner part, resulting in large warpage.
Lamination conditions have also been studied from the viewpoint of improving characteristics.

小さくかつそりの小さい積層板を製造できる。C5にな
った。In recent years, advances in mounting technology for base materials and technology for impregnating base materials with resin have made it possible to obtain laminated materials with uniform resin content, density, and degree of resin curing. Also, in lamination,
In order to reduce the occurrence of voids, a vacuum molding technique has been developed in which the atmospheric pressure around the laminate is lowered. These basic technologies enable low-pressure molding, making it possible to produce laminates with small thickness deviations and small warpage. It became C5.
しかし、プリント配a8iへの電子部品の自動実装化が
進み、積層板に対しては尚−層のそり特性の向上が望ま
れる現状にある。そこで多数枚成形におけるそりのばら
つきを検討したが。However, as electronic components are increasingly automatically mounted on printed A8I panels, it is desired to improve the warpage characteristics of the laminates. Therefore, we investigated the variation in warpage in molding a large number of sheets.
jl!l側のそりが大きいという欠点は未解決である。jl! The drawback of large warpage on the l side remains unresolved.
本発明は、熱板側積層板のそり特性を向上する製造方法
を提供することを目的とする。An object of the present invention is to provide a manufacturing method that improves the warping characteristics of a hot plate side laminate.

擦係数をf12以下、積層圧力を80kg/−以下とす
る方法である。In the present invention, a laminated material made of a required number of resin-impregnated paper cloths and gold #4 mirror plates are stacked alternately, and shoes are placed on the outside of the layered material. In manufacturing a laminated plate by heating and pressing upper and lower hot plates through a tonne material, this is a method in which the coefficient of friction at the interface between the cushion material and the end plate is set to less than f12, and the lamination pressure is set to less than 80 kg/-.
本発明者は、熱板側積層板にそりを生ずる原因はクツシ
ョン材が摩擦力と圧力によって接する鏡板を拘束するに
あることにあり、したがって上記の条件によると熱板側
積層板のそりが小さく、多数枚成形においてもそり特性
のばらつきが小さいことを確認した。The inventor believes that the cause of warpage in the hot plate side laminate is that the cushioning material restrains the end plate in contact with it by frictional force and pressure, and therefore, under the above conditions, the warpage of the hot plate side laminate is small. It was confirmed that the variation in warpage characteristics was small even when molding a large number of sheets.
クツション材と鋳板との界面摩擦係数を小さくするには
、両材料の相互に接する各面を改質する方法による。鏡
板については、ばラー研犀仕上げの向上、テフロンコー
ティングをする。In order to reduce the coefficient of interfacial friction between the cushion material and the cast plate, there is a method of modifying each surface of the two materials that are in contact with each other. For the mirror plate, improve the abrasive finish and coat it with Teflon.
クツシロン材については、テフロン等の低摩擦係数材シ
ートを使用する。As for the material, use a sheet of low friction coefficient material such as Teflon.
積層材料と金属鏡板を交互に槓み亜ね、さらにその外側

においては、クツション材が接する鏡板の平面方向の熱
膨張を拘束するため、成形中の熱板側積層板の上下の鏡
板の挙動に違いを生じ、その結集積層機中に歪みが生じ
、そりを発生する。In multi-layer molding, in which the laminated material and the metal mirror plate are alternately pressed together, and then heated and pressed with a hot plate via a cooker material on the outside, thermal expansion in the plane direction of the mirror plate in contact with the cushioning material is restrained. This causes a difference in the behavior of the upper and lower mirror plates of the hot plate side laminate during molding, causing distortion and warping in the laminating machine.
したがって、本発明の製造条件によると、クツション材
が鏡板の熱膨張を拘束することが少ないから熱版側積層
板上下の硯鈑の挙動がほぼ同じとなり、熱板側積層板の
そり特性が向上する。Therefore, according to the manufacturing conditions of the present invention, since the cushioning material hardly restricts the thermal expansion of the end plate, the behavior of the inkstone plates on the upper and lower sides of the hot plate side laminate is almost the same, and the warpage characteristics of the hot plate side laminate are improved. do.
