ABSTRACT:
A highly accurate circuit pattern in intimate contiguous relationship with a curved plastic body and a method of manufacture thereof. In accordance with the present invention, circuit pattern is detachably fixed to a flexible substrate and is placed into a mold. A molding compound is then forced into the mold pressing the circuit against the mold wall and filling all of the mold voids. The molded product is thereafter removed from the mold. The flexible substrate, on which the metallic circuit is printed, is removed from the molded product leaving the metallic circuit imbedded into the molded product.
