In an electronic apparatus comprising a circuit board supporting semiconductor components and traces or conductors for supplying electrical energy to the semiconductor components, and a connection arrangement by which the conductors are connected to a power supply cable, the circuit board being covered by an electrically insulating encapsulating layer, a molded frame part is mounted on the circuit board so as to cover the connection arrangement, the molded frame part having a circumferential edge structure which extends on one end into the encapsulating layer and at the other end projects above the encapsulating layer so as to create an interior space which, when the encapsulating layer is at least partially cured, is filled with additional encapsulating compound to form, after curing, a relatively thick protective layer over the wire or cable and conductor connecting area.
