Hprobe, Now Part of Mycronic, Develops Powerful New Magnetic Instrument for Testing TMR Sensors 

December 17, 2025 Editorial Staff 0

Magnetic sensor ICs have become essential to modern electronics, enabling accurate detection of position, speed, current and orientation. Among them, tunnel magnetoresistance (TMR) sensors stand out for their high sensitivity, low power consumption and seamless fabrication compatibility. Over the past decade, they have moved from research prototypes to large-scale adoption. Their growing complexity requires precise wafer-level control of 3D magnetic fields in terms of orientation, magnitude and uniformity, creating new technical and throughput challenges for sensor manufacturers and test equipment suppliers.
