Disclosed is a multilayer electronics packaging structure, especially for use in a multi chip module. By forming an overlap of signal conductors by the respective mesh conductors, an improved shielding effect is achieved and coupling between signal conductors is reduced. By increasing the via punch pitch such that multiple wiring channels are formed between adjacent vias, wirability is improved and the number of signal distribution layers may be reduced. The new structure thus shows improved electrical properties over the state-of-the-art structures, combined with a cost reduction of about 35%.
