Welcome To Our Family of Thin Film Process & Test Solutions!
Hprobe's library of automated magnetic test regimes for MRAM and TMR sensors includes the following:

MRAM Test Regime:
Continuity Test - Contact open/short test > Contact resistance
DC/Pulsed Test - IV Switching test/breakdown test > Rmin/Rmax, TMR, switching voltage, VCR
Hysterisis Test - RH Switching test > TMR, coupling field, coersive field, anisotropic field, stability factor, remanence
Phase diagram - Pulse Sweep Hysteresis test > Critical current, PAP, AAP isotropic field, stability factor
BER Test - Write/read error test >Bit error test in standard and config. with burst capability
Sensor Test Regime:
Continuity Test - Contact open/short check > Contact resistance
Hysteresis/TMR - R-H test > TMR field, coupling field, coersive field, anistoropic field, stability factor, remanence
Breakdown - DC/AC breakdown voltage > Extract break down voltage using DC or AC current sweep
Angular Diagram - R (V. Deg.) curve > Extract R versus H angle curves
Stability - Sensor stability operation > Extract the sensor stability in operation conditions (temperature and continuous operation, etc.)
