Abstract: Plastic encapsulated ferrite core plug-in units are fabricated by an injection molding technique utilizing a hollow mold. Conducting paths on and through the units are transferred from the mold to the units such that the conducting paths are in a plane different from the nonconducting surface of the units. Copper plating applied to the entire unit is then removed from the plane established by the nonconducting surfaces only.
