Abstract

PURPOSE:To reduce the warpage of a thin laminated board by laminating and molding laminates in which copper foils with adhesive layers, in which specific quantities of adhesives mainly comprising an epoxy resin are applied onto copper foils, are arranged onto top faces and/or undersides in which required numbers of resin impregnated base materials are superposed. CONSTITUTION:Laminates in which copper foils with adhesive layers, in which adhesives mainly comprising an epoxy resin are applied onto copper foils in 15-60g/m<3>, are disposed onto top faces and/or undersides, in which required numbers of resin impregnated base materials are stacked, are laminated and molded, thus obtaining a laminated board in thickness of 1.2mm or less. Phenol resin, cresol resin, an epoxy resin, etc., are used as the resin of the resin impregnated base material. A woven fabric, a nonwoven fabric, etc., composed of inorganic fiber such as glass, asbestos, etc., organic synthetic fiber such as polyester, polyamide, etc., and natural fiber such as cotton are employed as the base material. A crosslinking agent, a curing agent, a curing accelerator, a coloring agent and a solvent are added to the epoxy resin as required as adhesives. It is favorable that the copper foil with a thickness of 0.018-0.07mm is used as the copper foil.

The laminate has a wt9C circuit formed on the gold R foil on its surface and is used for printed wiring boards and multilayer printed wiring boards, but recently there has been a demand for more compactness, and laminates with a thickness of 1.611M have been the mainstream. Thickness 1.2 (1) g instead of board
, 0.8n thin laminates are becoming mainstream. However, as the thickness of the laminate becomes thinner, there is a problem in that the deformation of the laminate becomes larger, which impedes automation in handling and temporary processing.

A mixture is used, and if necessary, a solvent such as water, methyl alcohol, acetone, cyclohexanone, or styrene is added to adjust the viscosity.As for the wood, it is made of inorganic uXi fibers such as plaster, asbestos, polyester, polyamide, polyvinyl μ, etc. These include woven fabrics, nonwoven fabrics, mats, paper, or combinations of these materials made of synthetic fibers such as alcohol and acrylic, and natural fibers such as cotton. As a contacting agent, it can be crosslinked as necessary to epoxy resins such as bisphenol type epoxy resin, Novohook type Evoki Vm resin, resol type epoxy resin, flexible epoxy resin, halogenated Evoki resin, Glycyl ester/L' type Evoki resin, etc. Add agent, curing agent, curing accelerator, coloring agent, and solvent, and then add P≠Fu 4/ Tree II! as necessary. -Rubber, phenol/L/resin,
Although it is made by adding melamine resin or the like, it is necessary that epoxy resin be the main component. It is preferable to use the steel foil with a thickness of o, ois to O, Q7 fl, but it is not particularly limited. The thickness of the adhesive applied to the steel foil is 15 to -fAf. That is, if it is less than 15 f/n1, sufficient adhesive force will not be obtained, and (a) if it exceeds νI, the resistance will increase. The thickness of the laminate needs to be 1.20 or less. In other words, the product N of 1.2ffJ exceeds 1.2ffJ! This is because the young fruits of the present invention, which are slightly warped in terms of wood quality, do not become noticeable in the case of Ikari. For molding and sound molding, a multi-stage press method, a multi-roll method, a double belt method, a pressureless lamination molding method, a vacuum molding method, etc. are used, and there are no particular limitations.
