Title: Innovations of Soon-Jin Cho in Printed Circuit Board Manufacturing
Introduction
Soon-Jin Cho is a prominent inventor based in Suwon, South Korea. He has made significant contributions to the field of printed circuit board (PCB) manufacturing. With a total of 5 patents to his name, his work has advanced the technology and processes involved in PCB production.
Latest Patents
One of Soon-Jin Cho's latest patents is a printed circuit board manufacturing system and manufacturing method. This invention discloses a method of manufacturing printed circuit boards that includes providing a substrate with a pad and an insulation layer covering the pad. The process involves acquiring an image of the substrate and analyzing it to obtain location information of the pad. A via hole is then formed by removing part of the insulation layer corresponding to the pad's location, followed by filling the via hole with a conductive material. This method improves process conformity, even when the substrate experiences partial or nonlinear deformation, allowing for greater flexibility in substrate design and enhanced integrity for circuitries on the printed circuit board.
Another notable patent by Cho details a method of manufacturing a printed circuit board that includes sequentially stacking an acid-resistant first cover layer and an alkali-resistant second cover layer over a copper foil. The process involves forming an intaglio groove by removing portions of the second cover layer, the first cover layer, and the copper clad laminate. A seed layer is then stacked over the intaglio groove, followed by the removal of a portion of the seed layer and the formation of a plating layer by plating the inside of the intaglio groove. This innovative method enhances the efficiency and effectiveness of PCB manufacturing.
