Thermal shock is mainly used to test the resistance of materials to extremely high or very low temperatures. This situation is similar to the situation of discontinuously in high or low temperatures. The thermal shock test enables various items to be tested in the shortest time. Changes or physical damage caused by thermal shocks are caused by changes in thermal expansion and contraction or changes in other physical values. Only by adopting the PID system can all kinds of products gain complete trust. The effects of thermal shock include electrochemical changes caused by product cracking or cracking and displacement. The full digital automatic control of the PID system will make it easy for you to operate.
1. Application of thermal shock test machine:
Thermal shock testing machine is widely used in electronic and electrical components, automation components, communication components, auto parts, metals, chemical materials, plastics and other industries, defense industry, aerospace, military industry, BGA, PCB base board, electronic chip IC, The physical changes of semiconductor ceramics and polymer materials, the repeated resistance of the material to high and low temperatures, and the chemical changes or physical damage of the product due to thermal expansion and contraction, can confirm the quality of the product, from precision IC to heavy Mechanical components can be used as a basis or reference for product improvement.
