температурни циклус

температурни циклус

A test whereby devices are stored for short periods (15 minutes) alternately at high and low temperatures in gas filled chambers, with a maximum transfer time between chambers of one minute. Normally 10 cycles are performed from -65° to + 1 WC. This stresses device assembly because of the different thermal coefficients of expansion of the various materials used.
