なるという問題があった。[Background technology] Polyester resin impregnating power CEM made by laminating polyester resin-impregnated glass cloth on both sides of lath nonwoven fabric
- When making Type 3 copper-clad laminates, it is necessary to use a soft resin with a low heat distortion temperature in order to satisfy punching workability, but in such a case, the heat resistance and electrical properties may be insufficient. Conversely, when a resin with a high heat distortion temperature is used, the electrical properties and heat resistance are good, but there is a problem in that the punching workability is insufficient.
この発明は、このような事情に鑑み、打抜加工性が良好

れは、少なくともガラスクロスに対して行なえばよい。According to the authors' findings, this purpose was to divide the polyester resin-impregnated mold into two parts, the front and the front, and impregnate the resin with a low heat distortion temperature first, and then impregnate the resin with a high heat distortion temperature. This can be achieved by impregnation. This may be done for at least the glass cloth.

る。Therefore, in obtaining a laminate by superimposing and curing unsaturated resin-impregnated glass cloth on both sides of an unsaturated resin-impregnated glass nonwoven fabric, at least the glass cloth is prevented from being thermally deformed. The gist thereof is a method for manufacturing a laminate, which is characterized in that it is impregnated with an unsaturated resin having a temperature of less than 70°C, and then impregnated with an unsaturated resin having a heat distortion temperature of 70°C or higher. This will be explained in detail below.

処理は必須ではない。The pretreatment can be performed by impregnating and drying with a general solvent diluted solution. The heat deformation temperature of the unsaturated resin for pretreatment is 70°C.
Vinyl ester resin with a temperature of less than 30℃, preferably 30℃ or less! Fatty or unsaturated polyester resins are preferably used. A reaction initiator usually does not need to be added. The amount of treatment (amount of impregnation) is preferably 5 to 50% by weight, and 10 to 20% by weight.
The person in charge is especially nice. For glass nonwovens, this pretreatment is not essential.

好−ましくは１００℃以上のビニルエステル樹脂または
不飽和ポリエステル樹脂が好ましく用いられる点で異な
るのみで、処理方法や処理量は前処理と同じである。For post-treatment, the type of unsaturated resin must have a heat distortion temperature of 70°C or higher.
The only difference is that preferably a vinyl ester resin or an unsaturated polyester resin having a temperature of 100° C. or higher is used, and the treatment method and treatment amount are the same as in the pretreatment.

くは片面に重ね合わされる。A long length of glass cloth and glass nonwoven fabric is immersed in a treatment solution and dried, and both glass cloth and glass nonwoven fabric are passed between rolls with the glass cloth overlapped with each other, and passed through a curing furnace. A typical embodiment of the present invention is to obtain a laminate by continuously performing the process under no pressure. However, it is not limited to this. There is no particular limit to the number of layers of glass cloth or glass nonwoven fabric. If necessary, metal foils such as copper foil are laminated on both sides or one side.
