1970sTackled the challenges of measurement technologies and ultrafine process technologies

MJC began with just three employees providing electronic equipment maintenance services. Soon the company focused on semiconductor testing and precision measurement, and began product development using electronic measurement technologies and ultrafine process technologies. Japanese technologies helped MJC develop and launch the first probe cards and manual wafer probers.

Nov. 1970: Establishes Towa Electric in Tokyo's Meguro Ward to provide maintenance services for synchroscopes, facsimiles, industrial semiconductors and vacuum test systems.

1980sEstablished probing technologies

MJC opened a probe card production base in Aomori, Oita and Kumamoto prefectures that formed the foundation for its success as a probe card manufacturer. Utilizing probing technologies in semiconductors, MJC created and launched testing equipment for liquid crystal displays (LCDs) that would become a world standard.

2000sTackling new challenges using MEMS and systems technologies

MJC commercialized a proprietary microelectromechanical system (MEMS) probe card that has made it possible to measure in batch simultaneously for the first time in the world. This technology has also led to a number of other novel technologies, such as automated optical inspection (AOI) equipment for LCDs and semiconductor built-in self-tests (BISTs). MJC also expanded its locations outside Japan in association with increasing overseas sales.
