Hanwa Electronics Industry Co., Ltd. was founded in 1966 and began independently developing testing equipment for use in the semiconductor field in the 1980s. The ESD (Electronic Static Discharge) static damage testing machine was originally developed with only 256 pins, but now it can even achieve 1024 pins according to customer needs, meeting higher-level wafer testing requirements. In addition, Hanwa Electronics has expanded its analytical equipment and developed a TLP (Transmission Line Pulse) testing device with multifunctional detection and ESD protection circuit functions. With the development of the company, it has not only gained favor from local Japanese enterprises, but also gained unanimous recognition from overseas customers in the global market.
