  • Patent number: 10178773
    Abstract: Provided is a method for manufacturing a metal printed circuit board, the method including: printing a circuit pattern on a release film; applying a heat conductive insulating layer on the circuit pattern; laminating a heat conductive base layer on the heat conductive insulating layer and hot pressing the laminated heat conductive base layer and the heat conductive insulating layer; and removing the release film therefrom.
    Type: Grant
    Filed: December 24, 2012
    Date of Patent: January 8, 2019
    Assignee: INKTEC CO., LTD.

  • Patent number: 10080299
    Abstract: Provided is a manufacturing method of a double-sided printed circuit board. In the method, a first conductive circuit pattern configuring a circuit is formed on an upper side of an insulation layer, and a second conductive circuit pattern configuring a circuit is formed on a lower side of the insulation layer. A through hole vertically passing through the insulation layer is formed, and a conductive material is formed on an inner circumferential surface of the through hole such that the first circuit pattern and the second circuit pattern are electrically connected by the through hole.

  • Patent number: 9313900
    Abstract: Disclosed is a method for manufacturing a double-sided printed circuit board (PCB) having a circuit pattern by printing a conductive paste. According to the method of the present invention, a circuit pattern that is precise and highly conductive can be formed, and a reduction in raw materials and the simplification of processes are made possible. Also, due to the printing of the conductive paste, short-circuit can be prevented even when a conductive layer is bent or exposed to heat or physical impact.
