Apart from the process shown here, which is used in series production, there is a variant in which the conductor pattern is transferred from a carrier film and this is removed from the workpiece after the injection moulding process.
Another variant of the in-mold technology uses a multilayer foil made of copper and aluminum. The copper layer is structured before injection moulding, and the aluminium layer is etched from the finished substrate. This process allows the use of PPS as substrate material.
