[Background technology 1] When using metal foil-clad laminates for printed wiring boards, so-called punching workability is often a problem. A so-called combo knot laminate is used, in which the intermediate layer of the board is made of non-woven fabric. however,
This composite laminate has problems such as poor interlayer adhesion, heat resistance properties, etc. because it uses nonwoven fabric. Therefore, in order to solve the above problem, conventional patent applications No. 59-459'92, VF Application No. 59-71242, etc. have proposed non-woven fabrics containing inorganic fillers and coupling agents. However, even with these methods, interlayer adhesion and heat resistance properties were still insufficient.

The present invention will be explained in detail below. The resin-impregnated nonwoven fabric 3 is formed by impregnating a nonwoven fabric with resin varnish and drying it.The nonwoven fabric can be made of inorganic fibers such as glass or asbestos, synthetic fibers such as polyamide or polyester, or natural fibers such as paper. It is a blended fabric, a nonwoven fabric, or a mat, and it is possible to use a fabric in which fibers are bonded with a synthetic resin binder, or a fabric that utilizes the entanglement of fibers. Resin varnish is made by dispersing resin, inorganic filler 2, etc. in a solvent, and epoxy resin, 7-el resin, unsaturated polyester resin, polyimide resin, polyamide resin, etc. are used as the resin. However, it is particularly preferable to use thermosetting resins such as phenol resins, epoxy resins, and unsaturated polyester resins. Further, as the inorganic filler 2, inorganic particles 6 such as calcium carbonate, silica, aluminum hydroxide, etc. can be used, and it is particularly preferable to use aluminum hydroxide, which has low electrical conductivity. The electrical conductivity of aluminum hydroxide used here is not particularly limited, but is preferably 50
A value less than μv/cm is desirable. This is because if it exceeds the above range, the electrical insulation will deteriorate. As shown in FIG.
The varnish is mixed with the above varnish, and as the coating material for the inorganic filler 2, epoxy 04 resin containing an amine hardening agent is used.
A solution diluted with a solvent such as K can be used.

In addition, the particle size of the inorganic filler 2 is preferably about 1 to 300 μm; if the particle size of the inorganic filler 2 is outside the above range, the effect of improving adhesive strength, heat resistance, etc. will be poor. It is.

On the other hand, the resin-impregnated woven fabric 4 is formed by impregnating a woven fabric such as glass, which is generally used for this type of laminate, with a tree varnish that does not contain the inorganic filler 2 and drying it.
As the resin used for the resin varnish, the above-mentioned thermosetting resins and the like can be used. Using the resin-impregnated nonwoven fabric 3 thus formed as an intermediate layer, copper foil, aluminum foil, stainless steel copper foil, nickel foil, or brass foil is applied to the resin-impregnated nonwoven fabric 3 via the resin-impregnated woven fabric 4 as shown in FIG. A metal foil-clad laminate A is obtained by molding metal Yi5 such as MtWI and heating under pressure.

Therefore, by making a so-called composite shift laminate using woven fabric and non-woven fabric, it has excellent punching properties compared to the case where only woven fabric is used as a base material. By creating an inorganic filler 2 coated with the resin layer 1 and using this inorganic filler 2 as a filler for combo knot laminates, it is possible to improve the interlayer adhesion strength and prevent peeling of the surface layer during punching. It is something that can be prevented. Furthermore, it is possible to improve heat resistance properties and improve reliability during processing and as a final product.
