Abstract
Abstract An elongated composite tape structure including an elongated carrier, and a plurality of sinterable, thermally fusible tape strips of different characteristics disposed on the elongated carrier. Also disclosed is a reel-to-reel process wherein the composite tape structure as stored on a reel is incrementally processed by longitudinally feeding the tape structure through one or more processing stations at each of which the tape is driven in an indexed manner so that predetermined portions of the tape are processed at each station for substantially the length of the tape structure.
