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.
Claims6
A mold for use in an insert molding apparatus for making an insert molded electrical circuit from a lace curtain including a plurality of electrical connectors joined by at least one interconnect joint, the apparatus including a press and means for injecting an insulating material, the mold comprising:
- a cavity configured to receive the lace curtain, the mold including an aperture leading from exterior of the mold to the cavity,
- means for operatively connecting the aperture to the means for injecting the insulating material;
- and
- a punch and means for connecting the punch to the press, the punch having a severing position, the punch arranged to sever at least one of the interconnect joints while the lace curtain is in the cavity and the punch is in the severing position.
