COPPER FOIL WITH CARRIER AND PRINTED BOARD COMPRISING THIS COPPER FOIL

摘要

A piece of copper foil with a carrier characterized by comprising a resin layer having an area smaller than that of the piece of copper foil in such a way that the periphery of the piece of copper foil is not provided with the resin layer and a printed board using such copper foil are disclosed. The resin layer having an area smaller than that of the copper foil piece is formed on the copper foil piece by screen-printing. The handlability of the copper foil is improved. Contaminants such as resin powder do not adhere to the copper foil during cutting. Further, scratches by foreign matters, dents, damages, creases, and breakage during cutting, packing, and transportation are effectively prevented.
