MEMBRANES FOR APPLICATION OF ELECTRICAL CONDUCTORS TO A SUBSTRATE

LIP 23/001 AU3 There is provided a flexible membrane suitable for applying a pattern of electrical conductors to a substrate, the membrane having a first surface that includes a pattern of grooves, the grooves being loaded so as to be substantially level with the surface of the membrane with 5 a composition that includes particles of an electrically conductive material and an adhesive. The composition loaded in the grooves is adapted to become electrically conductive and ungrooved parts of the first surface are substantially devoid of the composition. The membrane is such that upon pressing it and the substrate against one another, the composition in the grooves adheres more strongly to the substrate than to the membrane, and such that subsequent separation of the 10 membrane from the substrate results in transfer of the pattern from the membrane, the composition remaining on the substrate in a pattern mirroring that of the grooves.
