Abstract
A method of making a combined sinter-ready silver film and carrier comprises the steps of: a) creating a carrier comprising designed openings; b) casting a silver film layer into the designed openings, for example casting a silver paste; and c) drying the carrier and silver film layer to form the combined sinter-ready silver film and carrier. The carrier may comprise a plastic carrier, which may be created by permanently bonding two plastic films, using a plasma bonding process or using a temperature stable glue. The carrier may comprise a stencil layer and a backing layer. The stencil layer may define the designed openings. The backing layer may be configured for sealing a bottom of the designed openings, wherein at the start of step b), a top of the designed openings may be open for receiving the cast silver film layer.
