Temperature cycle

Testing to investigate the resistance of electrical and electronic components to temperature environments. The test temperature conditions vary depending on the usage environment of the components, but mainly include the following three items.

1. Resistance to maximum temperature
2. Resistance to minimum temperature
3. Resistance to changes from maximum to minimum temperature and vice versa

Items 1 and 2 may involve temperatures as high as 300°C and as low as -50°C, depending on the component.
Item 3 mainly examines the resistance to expansion caused by heating and contraction caused by cooling. In this case, stress caused by differences in thermal expansion coefficients of the materials composing the component can lead to defects, so heating and cooling are repeatedly applied a specified number of times to examine the resistance to temperature changes.
