Multilayer printed circuit board and method for making same
Abstract:
An exemplary multilayer printed circuit board includes a first circuit substrate, a third circuit substrate, a second circuit substrate between the first and third circuit substrates, a first anisotropically conductive adhesive layer between the first and second circuit substrates, and a second anisotropically conductive adhesive layer between the second and third circuit substrates. The first circuit substrate includes a first conductive terminal and a first through hole. The second circuit substrate includes a second conductive terminal and two through holes (i.e. second and third through holes). The third circuit substrate includes a third conductive terminal and a fourth through hole. The first anisotropically conductive adhesive layer fills the first and third through holes to electrically connect the first and second conductive terminals. The second anisotropically conductive adhesive layer fills the second and fourth through holes to electrically connect the second and third conductive terminals.
