Abstract:
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.
Abstract:
To form wiring 72 on circuit board 34 and conductor body 60b, metal ink 70 containing metal particles is dispensed by inkjet head 24 straddling the circuit board and the conductor body. Then, a laser is applied by laser emitting device 26 to the dispensed metal ink. By this, the metal ink to which the laser is applied is baked and wiring 72 is formed. Here, a laser corresponding to the laser emission amount per unit of area based on the material of the circuit board, which is resin, is applied to the metal ink on the circuit board, and a laser corresponding to the laser emission amount per unit of area based on the conductor body is applied to the metal ink on the conductor body By this, the metal ink on the circuit board and the metal ink on the conductor body is baked appropriately, and wiring is formed appropriately straddling the circuit board and the conductor body.

Abstract:
The invention relates to a contact system comprising a spring and an accordingly associated printed circuit board surface, with which the spring is in contact. The printed circuit board surface to be contacted is a carbon printed circuit board surface. Increased contact resistance between the spring and the carbon printed circuit board surface, which is associated with the contact system according to the invention, is furthermore compensated for by electric and/or electronic means. The spring that is used is provided with a spring force adapted to the carbon printed circuit surface.
