Advanced Backend Thermal Calibration. 

SigmaTek temperature wafer calibration platforms with units available for immediate delivery.                   

What We Offer

Calibration wafers, calibration of waferprobe temperature chucks, thermal plungers, calibration wafers

Wafer probe chucks require spatial thermal verification. Package test handlers rely on precise thermal plunger temperature. Controller drift affects yield and correlation. Automotive environments increase audit scrutiny. Thermal verification must be both advanced and accredited.

Precision RTD Temperature Calibration Wafers

The SigmaTek CW Calibration Wafer System integrates with the prober and/or chuck controller to enable fully automated, operator-free temperature calibration with statistical analysis and reporting. Our systems are ISO/IEC 17025:2017 accredited calibrated. Featuring low-drift PT-100 4-wire sensors, the SigmaTek CW Calibration Wafer achieves sensor-to-sensor accuracy < 0.03°C and absolute accuracy up to +-0.1°K (0.2K, k=2), and is available in 150mm, 200mm, and 300mm sizes with up to 29 sensors. Full-wafer multi-sensor mapping, automation-ready (ACR/AOC) - Units in stock and available immediately.

On-site Prober Calibration

Sigma Sensors offers on-site thermal chuck / prober calibration services globally, using the SigmaTek CW Calibration Wafer system, ISO17025 accredited and IATF16949 complaint. We can calibrate multiple probers in parallel, and work around your schedule, minimizing tool down-time and task-switching within your engineering team. Ideal for laboratories and production test-floors. Also available: remote calibration / rent a wafer.

Temperature Wafer and Thermal Plunger Calibration

We calibrate any RTD and TC temperature calibation wafer and thermal plunger. This includes KLA Tencor Sensarray and others. -75°C to +300°C. Standard turnaround: 5-10 days. For each calibration performed, we issue a calibration certificate to match your requirements. (traceable / ISO9001:2015 / ISO17025:2017)

Turn your broken third party wafer into a working SigmaTek system for roughly the cost of recalibration. You have a prober or other tool you want to trade? We are interested to hear from you.
