日本古河电气工业公司和古河电路箔材公司合作共同开发了下一代新型电子机器用印刷电路板用铜箔“Ｆ ＷＳ系列” ,并已批量生产投入市场。作为印刷电路布线板用的传统铜箔 ,表面粗糙度并不理想 ,有损于电子机器的高水平工作。新产品铜箔 ,是具有比光泽面粗糙度更小的平滑表面的 Furukawa Electric Co., Ltd. and Furukawa Electric Foil Co., Ltd. jointly developed the F WS series of copper foils for the next generation of new printed circuit boards for electronic machines and put them into mass production. As a conventional copper foil used for printed wiring boards, the surface roughness is not ideal, which detracts from the high level of work of the electronic equipment. The new product copper foil has a smoother surface than the glossy surface
