Patent ID: 6929975

Claim:
A method for producing an electronic package with a circuit arrangement secured to a support body and at least one electronic component, comprising the following steps: a) forming lead-throughs in the support body; b) applying to the support body a first metallizing layer forming the base metallization for the formation of a conductor structure, and to the openings of the lead-throughs for the formation of thermal vias and electrical vias, c) closing the vias, from the bottom side of the support body by means of a screen printing process with highly viscous screen printing material, d) applying a low viscous passivating layer on the entire surface of the top side and the bottom side ( 13 ) of the support body, e) selectively removing the passivating layer from certain areas on the top side of the support body, f) applying a second metallizing layer to the first metallizing layer in the areas freed of the passivating layer, said second metallizing layer forming the final metallization of a material having a low melting point, g) applying and contacting by a soldering process the at least one electronic component of the circuit arrangement on the top side of the support body.
