ABSTRACT:
A method and apparatus are provided for forming insert molded circuits. The process includes inserting a circuit network comprised of a lace curtain with a plurality of individual circuits which are connected by interconnect members into a mold and then separating the individual circuits in the mold by cutting the interconnect members while the lace curtain is in the mold. After the interconnect members have been severed, plastic is injected into the mold thereby surrounding the individual traces. A mold for performing the process is disclosed which includes a retractable punch arrangement.
