Patent ID: 8052881

Claim:
A method for manufacturing a multilayer printed circuit board, the method comprising: providing a plurality of laminate units, each of the laminate units including an electrically conductive layer with a circuit pattern defined therein, and a release layer releasably attached to the electrically conductive layer; providing a plurality of insulation layers, each of the insulation layers defining a metalized through hole therein; stacking the electrically conductive layers and the insulation layers alternately one on another such that adjacent electrically conductive layers are insulated by one insulation layer and the metalized through holes electrically connects the circuit patterns of the adjacent electrically conductive layers, and removing the release layer from the laminate unit after the electrically conductive layer being stacked onto the respective insulation layer, thereby obtaining a pre-laminated multilayer printed circuit board; and laminating the stacked electrically conductive layers and the insulation layers together to achieve a multilayer printed circuit board.
