Title: Jun Kasai - Innovator in Circuit Board Testing Technologies

Introduction

Jun Kasai, an accomplished inventor based in Kyoto, Japan, has made significant contributions to the field of circuit board testing. With a total of three notable patents to her name, her innovative approaches have the potential to enhance the reliability and performance of electronic devices.

Latest Patents

One of her latest inventions is a testing apparatus designed to detect sparking and partial discharge between wiring patterns on a circuit board. This apparatus is instrumental in determining whether a circuit board is defective. It features a constant current source that feeds a steady current to a wiring pattern being tested. A voltage measurement part captures the resulting voltage at the wiring pattern. The invention includes a normal state voltage gradient calculation part that computes a voltage gradient under normal conditions, without sparking or partial discharge. The determination part then assesses whether the voltage gradient remains constant by comparing the measured voltage results to an estimated voltage based on the normal state gradient, leading to a reliable determination of circuit board integrity.

Additionally, Jun developed an insulation inspection method and apparatus designed to inspect the insulation quality of wiring patterns. This apparatus applies voltage between inspection objects and utilizes a current control unit to manage the flow of two different currents. The first current is maintained until the potential difference between the inspection points reaches a pre-defined threshold. Once this threshold is met, a second current is supplied, ensuring accurate insulation inspection.
