Power On/Off Test

Test Standard: MIL-STD-883E, method 1006, intermittent Life, condition A
Purpose: The purpose of this testing is to determine the resistance of the electrical stresses generated by sudden cycling between "on" and "off" conditions.
Procedures:
Heat and control the temperature of the hot side at 70't;
TEC work for 5min(l=lmax), and power off, this is a cycle.
Repeated 5000 cycles.
Evaluation criteria: the variation of the resistance less than five percent.
