CHINA Three-Chamber high-low temperature impact test box NBC-LRCJ-80L -60 ℃

Overview  

This series of thermal shock testing machine is mainly used to test the resistance of materials to extremely high or low temperatures, which is similar to the situation of discontinuous high or low temperatures, and the thermal shock test can make various items complete the test in the shortest time. The changes or physical injuries caused by thermal shocks are caused by changes in thermal expansion and contraction or other physical values, and all kinds of products can be fully trusted by using the PID system. The effects of thermal shock include electrochemical changes caused by cracking or breaking layers and displacement of the finished product, and the full digital element automatic control of the PID system will make it easy for you to operate.

Hot and cold shock testThe purpose of the machine inspection

Thermal shock testing machine is widely used in electronic and electrical components, automation parts, communication components, auto parts, metals, chemical materials, plastics and other industries, national defense industry, aerospace, military industry, BGA, PCB base wrench, electronic chip IC, semiconductor ceramic and polymer materials physical changes, testing the repeated tensile force of the material to high-low temperature and the chemical change or physical damage of the product in thermal expansion and contraction, can confirm the quality of the product. From precision ICs to heavy machinery components, it can be used as the basis or reference for the improvement of its products.
