織布切れが発生する問題があった。Conventionally, laminates are made by impregnating a base material with a nonwoven fabric core and a glass fabric surface with resin, but by adding an inorganic filler to the resin for impregnating the nonwoven fabric, it has been possible to improve strength, reduce warpage, and improve through-hole reliability. However, when the amount of inorganic filler is increased, the viscosity of the resin increases, resulting in a decrease in the impregnability of the nonwoven fabric and the occurrence of breakage of the nonwoven fabric during impregnation.

The present invention has been made in view of the above-mentioned problems in the conventional technology, and its purpose is to provide high strength and warp without reducing the impregnating property of nonwoven fabrics or causing nonwoven fabric breakage during impregnation. The purpose of the present invention is to provide a small number of electrical laminates.

自重のみによる加熱無圧積層成形の各れでもよい。In the present invention, on the upper and lower surfaces of a resin-impregnated inorganic filler-filled nonwoven fabric,
For electrical laminates, which are made by laminating and molding a laminate in which resin-impregnated glass cloth is arranged and metal foil is further arranged on the upper and/or lower surfaces, an inorganic filler is added from the non-woven fabric impregnating resin. The amount of inorganic filler can be removed, or the amount of inorganic filler can be reduced, or the amount of inorganic filler can be increased as a whole, so that strength can be improved and warpage can be reduced. Detailed explanation.
As the resin used in the present invention, C alone, modified products, and mixtures such as phenol resin, epoxy resin, unsaturated polyester resin, polyimide resin, polybutadiene resin, thermosetting polyphenylene oxide resin, and fluororesin can be used. Non-woven fabrics with heavy machinery fillers are manufactured by non-woven fabrics in which aluminum hydroxide, talc, clay, glass powder, silica, calcium carbonate, alumina, magnesium carbonate, etc. are made into non-woven fabrics, either singly or in mixtures. The amount is 1 to 200@ per 100 M parts (hereinafter simply referred to as parts) of the nonwoven fabric, but the density is 0.1
It is preferable that it is 5 g/c4 or more. If necessary, the above-mentioned inorganic filler may be added to the resin for impregnating a glass nonwoven fabric in an amount of 10 to 200 parts per 100 parts of the resin. The nonwoven fabric is made of glass fiber, organic fiber, etc., and any nonwoven fabric including spunbond nonwoven fabric, glass paper, etc. can be used. As the glass cloth, any commonly used glass cloth can be used as is, and there are no particular limitations. Metal foils include copper, aluminum,
Iron, zinc, zinc, etc. alone or in alloys can be used, and if necessary, an adhesive layer can be provided on the adhesive surface. The lamination molding may be any one of heat-pressure lamination molding using a press, multi-stage press, multi-roll, double-held, etc., or heat-pressure lamination molding using only the own weight of the laminate.
