Multitest has released its MT9928 gravity handler that supports the special features of the recently launched ecoAmp Kelvin contactor. According to the company, the solution's proven temperature performance and highest positioning accuracy ensure cost-efficient and reliable tri-temp testing as well as highest test yield.

The MT9928 operates from -55°C to 155°C and temperature accuracy of ±2.0°C and stability of ±0.5°C. Soaking will never experience bottle necks with the MT9928, boasted the company. In case the large soak capacity is not sufficient, a soak booster is available that cuts the soak time by 50 percent. Larger packages—often seen for power ICs—will directly benefit from this.

Power ICs also often require Kelvin testing that only can result in high yield if the device-under-test (DUT) can be positioned very accurately into the contactor. The MT9928 supports this advanced requirement of Kelvin testing, stated Multitest.

High power ICs are the enabler for many state-of-the art electronics that are used for automotive and electro mobility applications in the energy and industrial sector, for lighting (LEDs) or for power control and management. Due to these applications they combine the requirements for high power of 500A and more with tri-temp test. Typical package types include TO, SO, QFN, DPAK and power modules.
