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.

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.
