RMT Ltd. has finished regular complex Qualification Program 2016 of TECs and sub-mounts.
Its objective is to quantify the reliability of RMT’s thermoelectric coolers referred to the beginning of 2017, to prove the TEC reliability meeting the requirements of the Telcordia GR-468-CORE standard and RMT internal specifications TU 8420 001-34609988-12.
More than 1000 TECs of 10 types were exposed to the mechanical (vibration, mechanical shock, die shear strength, lead integrity), environmental (temperature cycling, high temperature storage, power cycling, insulation resistance) and electrical (thermo-physical parameters check) tests.
The test results indicate that TECs and sub-mounts manufactured by RMT meet the requirements both of Telcordia GR-468-CORE and TU 8420 001-34609988-12.
Complete Report on the Qualification Program 2016 (English version) will be available on request not later than January 20, 2017. Please, contact RMT for the copy. learn more

RMT Ltd introduce the updated line of thermoelectric sub-assemblies in standard PS-28 flatpack style package. Elongated shape, 28pins and large open area and many possible thermoelectric cooler solutions are optimal for CCD and CMOS detector applications. The available TEC solutions have cold side from 4x4mm2 to 12x24mm2 (or 17x17mm2). Single- and multistage TECs (with enlarged cold side) are available for advanced temperature stabilization. The sub-assemblies in PS-28 package are primary focused on linear image sensors with photodiode arrays - for example, CCD matrixes, InGaAs linear image sensors. However, the large number of pins in a package and wide range of possible thermoelectric coolers inside create a universal solution for many other applications as well.

RMT Ltd introduce more than 20 new thermoelectric coolers with holes for "external cooling". Term "external cooling" means TEC attached to the entire assembly on a header, rather than to a heat-generating object. There are two typical cases where thermoelectric coolers with holes can be used: 1) powerful LD on TO-38/46/56/9 type headers with not enough space to mount TEC on a header, 2) already sealed (un-cooled) devices, where the advanced temperature stabilization gives extra benefits in terms of laser wavelength stability, optical power output, device lifetime or sensitivity.

RMT Ltd introduce a new product range - miniature thermoelectric heat flux sensors with ultra-high sensitivity level. Advanced high-density pellets placement technologies and high quality materials give up to 10 times more sensitive solutions than any analog on the market. RMT Heat Flux Sensors have miniature dimensions, IP67 class protection and patented self-calibrating method.

RMT Ltd introduce new DX8130 - tabletop laboratory for studying thermoelectric micro-generators (TEGs), testing their operating parameters, optimizing the design of thermoelectric devices converting thermal energy (energy harvesting) and analyzing TEG real output in different conditions.

RMT Ltd introduce new DX5150 Temperature Controlled Mount for accurate temperature stabilization of laser and optoelectronics devices on different TO-style headers. Customized header layout can be developed by request. DX5150 is a perfect solution for temperature-controlled operating of devices with and without an integrated TE cooler.

RMT finalized it’s regular Telcordia GR-468 reliability testing and released Reliability Report 2014. The results of complex reliability testing confirm that all RMT thermoelectric coolers fully meet Telcordia GR-468 standard requirements.

RMT Ltd introduce Z-Meter Mini - the ultimate tool for thermoelectric coolers express analysis now in small form-factor. It fits any pocket and provides fast and accurate analysis for TE Coolers by three main criteria (RMT patented): AC Resistance (ACR), Figure-of-Merit (Z) and Time Constant.

RMT Ltd introduce a new product line - thermoelectric micro-generators. Thermoelectric micro-generators harvest waste heat and convert it to usable output DC power. Small dimensions and heat-to-power conversion ratio make thermoelectric micro-generators perfect to power stand-alone wireless sensors and wireless sensor networks and wearable devices. Thermoelectric micro-generators provide battery-free, long-life time maintenance-free power supply solutions.
