Abstract
A composite material for use in making printed wiring boards comprising a carrier having releasable conductive fine particles on its surface. The composite is laminated to a substrate with the conductive fine particles facing the substrate and the carrier removed, leaving the surface of the conductive fine particles exposed. Printed wiring is formed using the conductive fine particles as its base, thus providing improved peel strength and permitting formation of fine wiring lines and spaces.
