Multilayer additive printed circuit
A multilayer printed circuit as well as printed passive and active electronic components using additive printing technology is provided. The fabrication process includes a substrate and a first conductive layer that is printed with conductive ink on the substrate. An insulation layer that has uniform thickness is printed on the first conductive layer and the substrate, less via cavities, test point cavities, and a surface mount component contact point and mounting cavities. The insulation layer is replaceable with resistive layer or semi-conductive layer to fabricate electronic components. The vias are printed with conductive ink inside of the via cavities. Additionally, a second conductive layer is printed on the vias and over the insulation layer. The insulation, resistive, or semi-conducting layer, the vias, and the conductive layers are repeatedly printed in sequence to thus form the multilayer printed circuit.

FABRICATION METHOD OF CIRCUIT BOARD
A fabrication method of a circuit includes drilling holes in a substrate, so as to form a plurality of first opening holes and second opening holes in the substrate. A cover film is attached onto the substrate, so as to cover the first opening holes and the second opening holes. A portion of the cover film covering the first opening holes is removed, so as to expose the first opening holes. The first opening holes are filled.

The manufacturing method of the flexible printed wiring board relating to an embodiment includes a step of preparing a metal foil clad laminate 1 including an insulating substrate 2 and metal foil 3 and metal foil 4 provided on main surfaces of the substrate 2, a step of forming a circuit pattern 5 by patterning the metal foil 3, a step of forming a peelable printing plate layer 6 on the substrate 2 so as to embed the pattern 5, a step of forming blind holes 7a and 7b where the pattern 5 is exposed inside by partially removing the printing plate layer 6, a step of printing conductive paste with the printing plate layer 6 as a printing mask, and filling the conductive paste 8 inside the blind holes, and a step of peeling off the printing plate layer 6 from the metal foil clad laminate 1.
METHOD FOR MANUFACTURING FLEXIBLE ARRAY SUBSTRATE
The present invention provides a method for manufacturing a flexible array substrate. The method includes, first, successively forming an adhesive layer, a passivation layer, a back-side drive circuit, a planarization layer, a flexible backing plate, and a front-side drive circuit and a display circuit, in a stacked arrangement, on a rigid support plate and then peeling off the rigid support plate and the adhesive layer to form a flexible array substrate having a double-sided circuit structure. The entirey process requires no steps of peeling, reversing, and then re-attaching of the flexible backing plate so that it is possible to avoid the issues of poor flatness and low yield resulting from improper or wrongful re-attachment of the flexible backing plate and thus, fabrication difficulty of a flexible array substrate having a double-sided circuit structure may be lowered down to thereby improve fabrication yield of the flexible array substrate.
Electrical Connection Method of Printed Circuit and Electrical Connection Structure of Printed Circuit
An electrical connection method of a printed circuit includes overlapping a base material and a thin member in which a thin conductor is mounted, forming a through hole which passes through the base material overlapped with the thin member in the overlapping and reaches the thin conductor of the thin member, and forming a printed circuit on the base material by a screen printing method using conductive paste. The through hole formed in the forming of the through hole is filled with the conductive paste in the forming of the printed circuit.
