SURFACE-TREATED COPPER FOIL FOR PRINTED-WIRING BOARD, COPPER PLATED LAMINATE SHEET FOR PRINTED-WIRING BOARD, AND PRINTED-WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a surface-treated copper foil for a printed-wiring board, in which a transmission loss is highly suppressed even at the time of transmitting a high frequency signal of the GHz band, which is highly adhesive between a copper foil and a resin substrate at a high temperature and excellent in durability under a severe condition, and which is hardly-short-circuited.;SOLUTION: A surface-treated copper foil for a printed-wiring board has a silane coupling agent layer on the surface formed with roughening particles. In said silane coupling agent layer, the average height of roughening particles is 0.05 μm or more and less than 0.5 μm, and the BET surface area ratio of said silane coupling agent layer is 1.2 or more.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
