J microTech Unveils LMS-91A Temperature Chuck Adapter

(Product News, 31 Oct 2006)

J microTechnology has introduced its LMS-91A temperature controlled chuck for its LMS-2709 Laboratory Microprobe Station. The chuck adds temperature control and enhanced heat sink capability, enabling measurements at non-ambient temperatures on the device being tested. The LMS-91A provides the advantage of low cost thermal electric (TE) temperature control to microprobe technology on bench-top test applications for scientists and engineers.

The chuck operates at a temperature range of minus 5 degrees to 130 degrees Celsius (C). The temperature changes approximately 2 seconds per degree with temperature stability at better than 0.2 degrees C. This allows rapid change in operating point temperature and a stable test condition. The chuck is isolated from the stage and microprobe station base to allow test of back-side active semiconductors. The LMS-91A thermal electric controller offers flexibility for routine and occasional measurements. Control temperature accuracy and easy operation are inherent with this product.

The LMS-91A attaches to translation stage of the LMS-2709. Its XYZ probe positioners are compatible to coplanar RF/microwave probes, triaxial, coaxial, and unshielded direct current (DC) needles. Test devices are held down by vacuum and manipulated in the same manner as on a non-temperature controlled chuck.

The LMS-2709 is a rugged and basic RF, DC probe station for research of advanced active and passive components as well as for educational training of university students in the discipline of microwave microprobing. Prices for the LMS-91A start at $6,000. Pricing can vary due to order configuration and shipping destination. Delivery is about 6 weeks.
