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%.
