Claim 15:
16. A method of manufacturing an electronic package which includes one or more electronic devices mounted on a substrate, including at least one cooling plate in contact with the one or more electronic devices, the method comprising the steps of:
placing the substrate between a first mold half and a second mold half, the first and second mold halves defining a molding cavity for molding the one or more electronic devices;
clamping the substrate between the first and second mold halves;
projecting a cavity insert which is movably located in the first mold half into the cavity in order to contact and apply a sealing pressure onto the at least one cooling plate;
encapsulating the one or more electronic devices by introducing a molding compound into the cavity at a first fill pressure; and thereafter
packing the molding compound in the cavity by applying a second fill pressure which is higher than the first fill pressure;
wherein the sealing pressure is maintained at values that are higher than the first fill pressure and the second fill pressure while introducing and packing the molding compound respectively.
