Abstract: A method of making a combined sinter-ready silver film and carrier (1) comprises the steps of: a) creating a carrier (2) comprising designed openings (5); b) casting a silver film layer (7) into the designed openings (5), for example casting a silver paste; and c) drying the carrier (2) and silver film layer (7) to form the combined sinter-ready silver film and carrier (1). The carrier (2) 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 (2) may comprise a stencil layer (3) and a backing layer (4). The stencil layer (3) may define the designed openings (5). The backing layer (4) may be configured for sealing a bottom of the designed openings (5), wherein at the start of step b), a top of the designed openings (5) may be open for receiving the cast silver film layer (7).
