Sheet material esp. suitable for bonding electrical connections to a substrate has an adhesive layer (I) and a monolayer of individual , separate electroconductive particles (II), dispersed in (I), which is at thick as or thicker than (I), and a thin layer of insulating material (II) over the (II) monolayer, which is (almost) tack-free at room temp., has a resistance of min, 1 Mohm in the direction to (II), becomes soft and fluid on heating and sets to a solid on cooling to room temp. The sheet is easy to handle and does not form an electrical connection at room temp. but, when pressed against a substrate and heated, forms an electrical coneections in which (II) protrude through (III) to the substrate. Pref. the material also has electroconductive layer(s) under the (II) monolayer, pref. on an insulating substrate. It pref. has numerous conductive strips on an insulating sheet, which pref. are narrow, parallel, elongated strips. (I) is electroconductive and this and/or (II) extends only over these strips or over both the strips and the spaces between them. USE/ADANTAGE - The material gives stable connnections with low resistance. It is useful for connecting small and closely adjacent contact points or terminals, e.g. of printed circuits or LCDs.
