Title: Katsuya Sangu: Innovator in Multi-Layered Printed Circuit Board Technology
Introduction
Katsuya Sangu is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of multi-layered printed circuit board technology. With a total of 3 patents to his name, Sangu has developed innovative solutions that enhance the production processes of printed circuit boards.
Latest Patents
One of Sangu's latest patents is a positioning apparatus used in a process for producing multi-layered printed circuit boards. This invention involves an X-ray irradiation device that issues X-rays to a board mark and projects the image of the board mark on a fluorescence screen. The fluorescence face visibly displays the image of the board mark, which can be captured by a CCD camera. The CCD camera images the board mark and the mask mark depicted on the photo mask overlapping together. The board and the photo mask are aligned by exposure stage so that the board mark and the mask mark coincide.
Another significant patent is a marking apparatus used in the production of multi-layered printed circuit boards. This apparatus is designed to form alignment marks, which improve the alignment accuracy of each layer during production. An X-ray generator irradiates X-rays at a standard mark in a core board, projecting the image of the standard mark on a fluorescence screen. The image is captured by a visible light CCD camera, allowing the position of the standard mark to be detected. Using this detected position as an alignment reference, the apparatus irradiates ultraviolet rays at dry film resist layers, imprinting the marks on photo masks and dry film resist layers.
