History
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.
