Abstract (en)
[origin: WO2017134331A1] In the manufacturing method of a multilayer printed circuit board and in a multilayer printed circuit board of the invention, at least part from insulating, conductive or semi-conductive layers remaining inside the multilayer printed circuit board there are manufactured a printed circuit board by using a roll-to-roll manufacturing method for two or several semi-finished printed circuit boards. Between the conductive printed layers of a semi-finished printed circuit board it is possible to manufacture electric vias connecting these by printing. A flexible multilayer printed circuit board is manufactured by connecting at least two semi-finished printed circuit boards face to face so that the pure surfaces of the metal foils of the semi-finished printed circuit boards remain outermost. After this holes can be manufactured through the flexible multilayer printed circuit board, which are metal-plated to produce an electric via.
