Temperature cycle

A test to investigate the resistance of electrical and electronic components to temperature environments. The test temperature environment varies depending on the usage conditions of the component, but mainly includes 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

For items 1 and 2, depending on the component, the maximum temperature can reach 300°C and the minimum temperature can be as low as -50°C.
Item 3 mainly examines resistance to expansion due to heating and contraction due to cooling of the component. In this case, stress caused by differences in the coefficient of expansion of the materials composing the component can lead to failures, so heating and cooling are repeated a specified number of times to investigate resistance to temperature changes.
