。In general, copper-clad J-boards are made by impregnating a paper base material with 4FJ II) 1 VW K of unsaturated polyester resin, etc., to create a resin-impregnated base material T, and multiple sheets of this are made as shown in the drawing. Lay the steel foil 3 on top of the laminate 1 through the laminated layer 2, and heat it (pressureless forming) etc. under no pressure. By rN, J is left behind.

、解決法が見いだされていないのが実情である。In this case, the amount of shrinkage when the resin component hardens due to heat treatment is
Adhesive layer 2 and laminate l are quite different, and adhesive layer 2
Since the curing shrinkage of the laminate is much larger than that of the laminate (which has a small curing shrinkage because it is reinforced by the paper base material), the resulting copper-clad laminate has a problem of warping in a concave shape toward the copper foil side. . In order to eliminate this warping, we used a paper base material with a large shrinkage lid in addition to the usual paper base material, and used this for the outer part of the laminate l furthest from the copper foil 8. It was thought that the resulting warping could be counteracted by shrinkage of the paper base material. However, the above-mentioned paper base material with a large amount of shrinkage has a large difference in shrinkage in the longitudinal direction and the transverse direction, which creates a new problem of twisting in the resulting copper-clad laminate. The reality is that no solution has been found.

いだしこの発明に歯達した。As a result of a series of studies to solve these problems, the inventors discovered that, prior to impregnating multiple base materials with resin liquid, the inventors found that After the base material constituting the outer part of the laminate is subjected to AIJ'yQl treatment with pretreatment resin, the side opposite to the metal foil is further coated with pretreatment resin, or The above gold 9 is used as it is without pre-treatment with a treatment resin.
4 Applying a pretreatment resin to the side opposite to the foil 7, and pretreating the base material that makes up the rest of the laminate with the pretreatment resin, the intended purpose is achieved. ! The prefecture was able to successfully develop this invention.

とをその要旨とするものである。In other words, this product is made of several pieces of pine (G') by impregnating a base material with a resin liquid and laminating it, overlaying a metal foil on this laminate via a first layer of adhesive, and subjecting it to a heat curing process. A method for manufacturing a foil-clad laminate, wherein, before impregnating a plurality of substrates with a resin liquid, four substrates forming the outer part of the laminate furthest from the metal layer among the plurality of substrates are impregnated with a resin liquid. After pre-treating the base material with pre-treatment resin, apply pre-treatment resin to the side opposite to the metal foil, or apply pre-treatment resin according to pre-treatment example 11tj. Pretreatment inJ!li+' is applied to the opposite side of the metal foil without any pretreatment, and the base material constituting the remaining part of the product is pretreated with pretreatment resin. The gist of this is to provide the following.

えられる。The reason that warping of the copper-clad laminate is almost eliminated by doing this is that the base material that constitutes the outer part of the laminate that is farthest from the gold foil has been pretreated with a pretreatment resin or has not been pretreated. This is thought to be due to the fact that the pretreatment resin is applied to the surface of the adhesive opposite to the metal foil, so that the amount of shrinkage caused by the pretreatment resin is well balanced with the amount of shrinkage when the adhesive layer is cured.

ように設定することか効果の点で好ましい。Application of the pretreatment resin to the base material that constitutes the outer part of the laminate furthest from the metal foil (hereinafter referred to as the "outer base material") is usually performed as follows. . In other words, for metal foil-clad laminates such as copper-clad laminates, melamine resin is generally applied to a base material such as a paper base material.
0 to 15 layers (hereinafter referred to as "excellent") impregnation (pretreatment)
However, when reapplying the pretreatment resin to the outer base material of such pretreated base materials, it is necessary to apply the pretreatment resin to the outer base material on the opposite side of the metal foil. A pre-treatment resin is applied and soaked using a bar code. In this case, from the viewpoint of effectiveness, it is most preferable to set the total pretreatment resin content to 20 to 30% in resin coating II. In addition, when applying pre-treatment fat for the first time on the outer base material of the temple umbrella, use a bar code on the side opposite to the metal foil of the outer base material to apply pre-treatment fat. Coating and impregnating are carried out. In this case, it is preferable to set the pre-treatment fat content to 1θ to 80cm from the viewpoint of effectiveness.

である。It should be noted that manufacturing the metal foil laminate using the outer base material coated with the above-mentioned pretreatment example 11f is carried out by a known method. That is, the above-mentioned outer base material and other base materials are impregnated with a resin liquid such as unsaturated polyester resin face, and then laminated so that the outer base material is on the outside of the laminate (on the opposite side from the metal foil). Then, a metal foil such as copper foil is layered on this laminate via an adhesive layer such as a vinyl ester resin adhesive, and pressureless molding is performed. Note that it goes without saying that pressure molding may be performed using a press or the like.
