加工でおこなわれている。In manufacturing electrical laminates, a resin-impregnated base material is created by impregnating a base material such as paper or glass cloth with a resin varnish such as phenol resin, epoxy resin, or polyimide resin and drying it. This is done by stacking a required number of base materials, overlapping metal foil such as copper foil on both or one side of the base materials, and then heating and pressing them to form a laminate. When holes such as through-holes are formed in a laminate, drilling is used when lath woven fabric is used as the base material, but punching is mainly used when paper or plush fabric (plush non-woven fabric) is used as the base material. This is done through processing.

用いられる電気用積層板を得ることができる。The method for manufacturing an electrical laminate according to the present invention is characterized by laminating and molding a resin-impregnated base material that is impregnated with a resin varnish containing magnesium silicate and subjected to llIgl. It is preferable to use fibrous magnesium silicate as the magnesium silicate used in the present invention, and this fibrous magnesium silicate is known as chrysotile or seviolite, and is commercially available from Daiji Yakuhin Kogyo Co., Ltd. There is Need Plus manufactured by Co., Ltd. For example, the composition of chrysotile is Mg6SLOto(OH)a, and the main component of Need Plus is 5in2・MgO・A1□
It is O1. As resin varnish, phenolic resin, epoxy resin,
Thermosetting resins such as polyimide resins and unsaturated polyester resins can be used. These resins can be used alone or in combination, and their modified products can also be used. It is used by blending magnesium silicate into a resin varnish and mixing it uniformly.The amount of magnesium silicate blended is preferably set in the range of 5 to 50% by weight based on the resin content of the resin varnish. If it is less than 5% by weight, the effect of preventing crack generation by incorporating magnesium silicate will not be sufficiently obtained, and if it exceeds 50% by weight, the surface appearance such as the smoothness of the laminate tends to deteriorate. Therefore, a resin-impregnated base material (prepreg) can be prepared by impregnating a base material such as paper or glass paper with the resin varnish containing magnesium silicate and drying it. Next, the required number of sheets of this resin-impregnated base material are stacked, and if necessary, metal foil such as copper foil is stacked on one side or both sides of the base material.
An adhesive may be applied to the side of the A4 fat-impregnated base material, if necessary. Then, by laminating and molding this by heating and pressurizing it, it is possible to obtain an electrical laminate that can be finished and used as a printed wiring board.

加工性を高めることができることが確認される。The invention will now be illustrated by examples. (Epoxy resin varnish (epoxy resin; Epicoat 1001 manufactured by Shell Chemical Co., Ltd.) prepared by K according to the formulation shown in Table 1,
Fibrous magnesium silicate (chrysotile) was mixed in the amounts shown in Table 1. Apply this epoxy resin varnish to 0.
A resin-impregnated base material having a resin content of 50% by weight after drying was prepared by impregnating a glass paper with a thickness of 2 mho and heating and drying it. This Q (7 sheets of fat-impregnated base material is stacked, and further copper foil is stacked on top and bottom of each layer, and 40
kg/cm and laminated for 120 minutes at 165° C. to obtain a 1.61 mm thick double-sided copper-clad glass paper base epoxy resin laminate. A 1.6 mm thick double-sided copper-clad glass paper base epoxy resin laminate was prepared in the same manner as in Examples 1 to 3 above, except that an epoxy resin varnish not mixed with magnesium silicate was used. Got the board. Regarding the laminates obtained in Examples 1 to 3 and Comparative Examples above,
Punching workability was measured. Punching workability was evaluated by visually inspecting the occurrence of cracks around the holes when holes were punched in the laminate. The results are as follows: ◎: No cracks occurred ○: Almost no cracks occurred ×: Cracks 72 occurred Table 1 (Amounts are in parts by weight) As seen in the results of Comparative Examples and Examples 1 to 3 in Table 1, It is confirmed that by mixing magnesium silicate with a resin varnish and using it, it is possible to improve the punching processability when punching an 8-layered board.
