Problems solved by technology

The common thermal shock test equipment adopts compressors, evaporators, condensers, etc. for refrigeration, and then adjusts the output temperature (roughly between -40°C and 200°C) through heating wires. This traditional thermal shock machine The structure and cooling and heating methods have slow heating speed, high energy consumption, and high cost, and the overall volume of the equipment is large, which cannot be moved with the application. When testing the components, the components can only be placed on the equipment. location, but the device cannot match the location of the tested component, lacking flexibility and convenience

Description

technical field [0001] The invention relates to the field of component testing equipment, in particular to a small-scale rapid thermal shock testing device. Background technique [0002] In the manufacturing process of semiconductors and components, especially the 5G chip type products that have developed rapidly this year, performance testing or reliability verification is required, including chemical changes or Physical damage, so need to use thermal shock testing machine. [0003] Fast heating and cooling speed, wide test temperature range and reduced energy consumption have always been the requirements for the improvement of the thermal shock machine. The common thermal shock test equipment adopts compressors, evaporators, condensers, etc. for refrigeration, and then adjusts the output temperature (approximately between -40°C and 200°C) through heating wires. This traditional thermal shock machine The structure and cooling and heating methods have slow heating speed, h...
