 Method of manufacturing copper foil for printed wiring board, and copper foil printed wiring board patent thumbnailMethod of manufacturing copper foil for printed wiring board, and copper foil printed wiring board
A method of manufacturing a copper foil for a printed wiring board, characterized in that a roughened layer of roughening copper grains is formed on at least one surface of the copper foil by using an electrolytic bath of sulfuric acid and copper sulfate, and the electrolytic bath contains tungsten ions and/or arsenic ions and further contains an alkyl sulfate-based anionic surfactant. The object of the present invention is to provide a method of manufacturing a copper foil for a printed wiring board, wherein in particular a roughened layer on the copper foil can be improved to enhance the adhesive strength between the copper foil and a resin substrate without deteriorating other properties of the copper foil..

 Process to manufacture surface fine grain copper foil with high peeling strength and environmental protection for printed circuit boards patent thumbnailProcess to manufacture surface fine grain copper foil with high peeling strength and environmental protection for printed circuit boards
The present invention relates to a manufacturing method for a fine grain surface copper foil with the low roughness, high peeling strength, high chemical resistance, high heat resistance, high resistance to moisture absorption and good etching properties, and applicable to all kinds of printed circuit boards. The technical characteristics are that the adhesion surface of copper foil is electroplated in an electroplating bath composed of copper sulfate, sulfuric acid, tungsten compounds to obtain a roughening treatment layer which is then treated with a electroplating copper foil method for anti-rust and thermoresistance known to the art to get a zn alloy thermoresistant layer..

Manufacture method of buildup circuit board
A manufacturing method of a buildup circuit board includes forming a wiring layer on an organic polymer insulating layer by copper electroplating and building up other organic polymer insulating layer on the wiring layer, wherein in a final step of the copper electroplating, a surface of the wiring layer is roughened by copper electroplating and the organic polymer insulating layer is formed directly on the roughened surface of the wiring layer. According to the invention, a specific etching step that is essential for enhancing adhesion between the organic polymer insulating layer and the wiring layer can be omitted and no expensive etching apparatus is necessary, thus being good in economy.
