In 1834, Peltier, a French physicist, found that through DC electricity one node becomes cold and the other one get hot in the closed circuit which is composed of two different metals. This effect was later named as the Peltier effect. Anot...(more)
Sorting, storing and finding a SMD (Surface Mount Device) - sometimes called SMT (Surface Mount Technology), components is not easy, this is because they are so tiny and there are so many kinds of them: different sizes, values, types, etc....(more)
The applications that need wider temperature control range, large size DUT, high power devices, fast thermal response, require higher TEC output power. Thermoelectric coolers are used for applications that require heat removal ranging from m...(more)
I am an electronics engineer, and my job includes both designing and testing. However, either designing or testing, we always use resistors and capacitors. But, usually, the values of the resistors and capacitors are not the same. We often...(more)
Sensors (English name: transducer/sensor) is a kind of detection device, sensing the measured information, and transform information into electrical signal according to certain rule or other forms of output information, for satisfying such...(more)
Thermoelectric coolers are operated by the Peltier effect which also goes by the more general name thermoelectric effect. The device has two sides, and when DC current flows through the device, it brings heat from one side to the other, so t...(more)
The laser is a device that a beam of light that is both scientifically and practically of great use because it is coherent light. The beam is produced by a process known as stimulated emission, and the word laser is an acronym for the phras...(more)
During the productive process, by controlling the material composition, sintering atmosphere, sintering temperature and the state of structure, we can control resistance under the same temperature, and also be able to control the value chan...(more)
