From compact low-cost models for research and development to fully automatic models for production!
Our probes have enhanced their functionality considering the measurement purposes of devices as pioneers of non-magnetic probes designed for magnetic mounting. We offer a lineup of models suitable for various measurement devices and techniques, such as magnetic memory, magnetic sensors, and magnetic storage. The fully automated models achieve high functionality with features like automatic angle and alignment of the probe, auto alignment, C-to-C, automatic profiling, and automatic position correction for large-diameter wafers. Additionally, we manufacture testers in-house, providing a consistent measurement test system. 【Features】 ■ The basic structure is completely non-magnetic. ■ Wafer evaluation for electronic compasses is thoroughly non-magnetized and equipped with three-axis coils. ■ Temperature measurement is possible from -40°C to +200°C while maintaining non-magnetization. ■ Utilizes low residual magnetic field technology for in-plane magnetic field, vertical magnetic field, and omnidirectional magnetic field application. *For more details, please download the PDF or feel free to contact us.
