Thermoelectric Cyclers, generators, modules, readily available

Description

We would like to propose our product, thermoelectric cooling module to your Company. SCTB NORD was established in ***1 in Russia. And currently the company is incorporated into the Japanese corporation – FerroTec corp. Our specialists have been working in the industry of thermoelectricity for over *0 years. Nowadays NORD is specializing in manufacturing the modules with special properties. Let us point out few technologies that enable us to provide the unique properties of thermoelectric module: 1. Application of polycrystalline TE material (patented); 2. Specific assembly technologies on the basis of elastic layers (patented); 3. Multilayer flexible Ni plating technology; 4. Application of gold plating onto Ni barriers. Applied polycrystalline material produced by extrusion has a considerably better mechanical strength in comparison with melted TE materials. It allows us to avoid the problems with built-in defects, arising in pellets during exploitation and particularly during the soldering process, when heating up at reflow process and then cooling down, which leads to strong mechanical stress. It is next to impossible to detect the cracking of fragile pellets made of melted TE material and they play a main role in failures of modules. NORD has the ability to apply high temperature solder with low active flux, due to the technology of Au-plating, which is the application of a gold layer on the Ni barriers in semiconductor wafers, thus decreasing the probability of statistic defects in solder junctions. Moreover, use of low active flux decreases the risks, of corrosion of the contacts which might appear due to condensed moisture inside the module, while it is in use. All of our modules contain an elastic glue layer on the cold side of a module, between copper pads and ceramic substrates. We patented and applied this technology since ***6. This approach gave us a possibility to increase the cycling reliability of modules by more than **0 times.
