のである。In the metal foil-clad laminate A, a plurality of uncured prepregs 3 impregnated with a base material are laminated and metal foils 2 such as copper foils are arranged on the upper and lower surfaces of these prepregs 3 ... The laminated body 5 is sandwiched between metal plates 1 and 1 such as mirror-finished mirror plates, and such a structure is laminated in multiple layers as shown in FIG.
The prepreg 3 between the metal plates 1 and 1 is energized to raise the temperature to a suitable temperature and the heating mold plates 4 and 4 are brought close to each other to apply heat and pressure.
Are cured by heating and the metal plates 1, 1 arranged on both sides of the prepreg 3 are integrated to obtain a metal foil-clad laminate A.

4％になった。In such a case, the surface area of the metal foil 2 which is in contact with the metal plates 1, 1 is larger than that of the prepreg 3 and also larger than that of the metal plate 1, so that the peripheral portion of the metal foil 2 is larger than the peripheral portion of the prepreg 3. The metal plate 1 is made to project and also to be projected more than the peripheral portion of the metal plate 1. Then, the metal plate 1,1
The resin burrs flowing out from the prepreg 3 are prevented from reaching the metal plates 1, 1 in a portion having a large area and protruding from the peripheral portion of the prepreg 3 when heating and pressing the prepreg 3 close to each other. . In this way, resin burrs are prevented from adhering to the metal plate 1 or entering between the metal plate 1 and the metal foil 2, which makes it difficult to separate the metal plates 1 and 1 from the product, It is possible to prevent defective products from being produced due to burr. Also, there is no need to remove the resin burr from the metal plates 1 and 1, and there is no need to cause hammering to the product during subsequent heating and pressing when the metal burs 1 and 1 are not removed sufficiently. is there. And, the disassembly time between the metal plates 1 and 1 and the metal foil-clad laminate A is conventionally 60 to 90 seconds /
In the method of the present invention, the number of sheets becomes one for about 30 seconds,
Also, the hitting defect was 1.8% in the past, but about 0.6
It became 4%.

る。[Effects of the Invention] In summary, according to the present invention, the surface area of the metal foil to be contacted with the metal plate is made larger than that of the prepreg, and the peripheral portion of the metal foil is projected more than the peripheral portion of the prepreg. When heating and pressing in close proximity, the resin burr flowing out from the prepreg is prevented from reaching the metal plate in the part that protrudes beyond the peripheral part of the prepreg and the resin burr adheres to the metal plate. And again
It is difficult to separate the metal plate and the product due to infiltration between the metal plate and the metal foil, defective products such as resin burr may appear, and work to remove the resin burr from the metal plate Avoids problems caused by resin burrs reaching the metal plate, such as punching of the product during subsequent heat and pressure, if this is bothersome and necessary and not adequately removed from the metal plate The surface area of the metal foil that can be contacted with the metal plate is smaller than that of the heating / pressurizing plate, so that the metal foil having a larger area than the prepreg does not stick out from the heating / pressurizing plate, and the upper / lower heating / pressing is performed. When a metal foil having a larger area than the prepreg is interposed between the plates and installed in multiple layers, the metal foil may protrude from the heating / pressurizing plate and hinder the installation work during heating / pressing. There is an advantage of being able to avoid.
