Abstract

The present invention discloses a printed circuit board and a method for fabricating the same, and an apparatus for fabricating printed circuit board. The printed circuit board includes a substrate having an upper surface; a first trench recessed from the upper surface of the substrate; a first via formed in the first trench and penetrating through the substrate; and a first conductive layer disposed in the first trench and the first via, the first trench being electrically connected to the first via. A method for fabricating the printed circuit board and an apparatus for fabricating the printed circuit board are also disclosed. The method and device utilize an ink-jet printing technology to fabricate the printed circuit board, can substantially simplify a technological process of the printed circuit board, and compared with a traditional technological process, can save many complex processes, improve the technological process and cost effectiveness, and reduce the pollution problem in a fabricating process.

Description

technical field [0001] The invention relates to a printed circuit board and its manufacturing method, as well as a printed circuit board manufacturing device, and in particular to a printed circuit board manufactured by inkjet, its manufacturing method and the printed circuit board manufacturing device. Background technique [0002] Printed circuit boards are an indispensable component of electronic products. Electronic components can be connected together through circuits on the printed circuit board, and the overall function can be exerted. The traditional method of manufacturing printed circuit boards includes forming an insulating layer on the printed electroplating board substrate; then forming a metal layer on the insulating layer, such as copper foil or aluminum foil; then partially shielding according to the circuit design and etching the unshielded part to form a wire ; If the printed circuit board is a multi-layer circuit board, the next step is to start lamination...
