Title: Innovations by Zhiyi Song in Circuit Board Technology
Introduction
Zhiyi Song is a notable inventor based in Kawasaki, Japan, recognized for his contributions to circuit board technology. With a total of two patents to his name, he has made significant advancements in the methods of producing double-sided circuit boards and thin film wiring boards.
Latest Patents
Zhiyi Song's latest patents include a method of producing double-sided circuit boards. This method involves forming multiple wiring pattern layers on the front surface of a substrate while maintaining an insulator protection film over the wiring pattern on the back surface. Once the wiring pattern layers are completed on the front, a penetrating hole is bored in the hardened insulator protection film, which can serve as a conductive via or through hole. This innovative approach eliminates the need for an additional process to remove the insulator protection film, thereby streamlining production and reducing costs. Another patent focuses on a thin film wiring board and its manufacturing method, which includes forming a dummy pad through a polyimide insulating layer to counteract defects in the via connecting pad on a ceramic substrate. This method ensures that any defects do not affect the layers above the dummy pad, enhancing the reliability of the final product.
