Abstract:
1. A method of manufacturing a combined multilayer circuit board having embedded chips comprising: (a) providing at least two multilayer circuit boards, wherein each multilayer circuit board is fabricated by: (b) combining the at least two multilayer circuit boards to form a combined multilayer circuit board, wherein the of combining comprises: (c) forming multiple outer conductive vias by drilling multiple through holes through the combined multilayer circuit board and then electroplating the peripheries defining the through holes to electronically interconnect the conducting wires and the conductive layers in the at least two multilayer circuit boards; and (d) forming circuits and contacts on the combined multilayer circuit board by etching patterns on the conductive layers and coating an insulating lacquer layer on a portion of the patterned conductive layers.
