ｆｔ用いることができるものである。The inner layer material used in the present invention is made of synthetic resins such as phenol resin, cresol resin, epoxy resin, unsaturated polyester resin, melamine resin, polyimide resin, polyurethane oxide resin, and fluorinated resin, and is free of glass, asbestos, etc.
Organic synthetic materials such as I fibers, polyester, polyamide, polyvinyl alcohol, polyurethane, polyimide, etc., woven fabrics, non-woven fabrics, mats, nets, etc. made of natural fibers such as cotton, etc.
The amount of resin after drying on base materials such as cheesecloth and paper is approximately ω% by weight (
(Hereinafter simply written as %) K is impregnated and dried to a thickness of 0. It is made by integrating a metal foil made of steel, aluminum, nickel, zinc, etc. alone, alloy, or composite on the upper and/or lower surfaces of the required number of O1 to IH resin-impregnated base materials, so-called single-sided metal cladding. This is called a laminate or double-sided metal-clad laminate. The degreasing treatment of the inner layer material is not particularly limited, but it is preferable to use an inorganic acid such as hydrochloric acid, a solvent such as isopropyl alcohol, and an additive such as a surfactant. As the acid-containing rinsing liquid, an aqueous solution containing hydrochloric acid or the like is used, but it is preferable to use a primary rinsing liquid after pickling treatment, since this is also effective in utilizing the treatment liquid. For the soft etching treatment, rinsing treatment, pickling treatment, and rinsing treatment, commonly used treatment methods can be used.
以下本発明を実施例にもとづいて説明する。The present invention will be explained below based on examples.
