Products introduction

The rapid thermal cycle box can simulate the repeated rapid temperature change test of the parts after the driving environment of the car. It is suitable for the adaptability test of the whole machine and parts of electronic and electrical products under the condition of rapid temperature change or gradual change, especially for the Environmental Stress Screening (ESS) test of electronic and electrical products, using the temperature acceleration technique to change the external environmental stress, Thermally stresses and strains the product.


Product alias: rapid thermal cycle box, temperature rapid cycle test box, rapid temperature cycle box, rapid temperature stress screening machine, temperature and humidity cycle stress screening test equipment.
