Title: Kiyoshi Hani: Innovator in Printed Wiring Board Technology
Introduction
Kiyoshi Hani is a notable inventor based in Amagasaki, Japan. He has made significant contributions to the field of printed wiring board technology, holding a total of 8 patents. His innovative work has paved the way for advancements in electronic manufacturing processes.
Latest Patents
Among his latest patents is the invention of a metal-core printed wiring board and a process for its manufacture. This method involves laying a plurality of prepreg sheets composed of ceramic paper, which contain varying quantities of resin, on each side of a core metal sheet that has a through hole. A copper foil is then placed on the prepreg sheets on both sides of the core. The layers are pressed together under heat to create a metal-core printed wiring board. The prepreg sheets serve as an insulating layer with high heat-dissipating capacity on each side of the core, as well as a reliable insulator in its through hole. The ceramic paper is primarily made of short ceramic fibers, with a diameter not exceeding fiber microns and a length ranging from 5 to 500 microns. It also contains 3 to 10% by weight of microfibrillated cellulose fibers, which act as a binder for the ceramic fibers. Another significant patent involves the development of inorganic paper, which is produced through a paper-making process from a mixture consisting essentially of specific materials.
