ABSTRACT:
A method of selectively applying adhesive to the tops of ribs on a ribbed-substrate. The method includes the steps of applying a layer of adhesive to a flexible, polyimide carrier; drying the adhesive layer; rolling the ribbed substrate against the carrier so that the adhesive layer contacts the rib tops but does not contact the substrate in the regions between the ribs; and separating the adhesive from the carrier, thereby depositing the adhesive on the rib tops. The ribs typically have heights and widths from about 1 to 10 .mu.m, and are separated by distances of 1 to 10 times those dimensions.
