Abstract:
A method of manufacturing a multilayer circuit substrate comprising the steps of:(a) providing at least two circuit substrates, wherein each circuit substrate has at least one layer of circuit patterns;(b) providing at least one connecting member for connecting said circuit substrates, wherein said connecting member comprises an organic porous base material having a top surface and a bottom surface, each surface having a tack free film disposed thereon, and each connecting member has at least one means defining a through hole running throughout the connecting member, each through hole being filled with conductive resin compound up to the surface of each tackfree film;(c) separating each tackfree film from said connecting member such that the conductive resin compound sticks out from the surface of the organic porous base material at substantially the same thickness as that of the tack free film;(d) positioning said connecting member between the circuit substrates; and(e) heating and pressurizing.
