Testing procedure
1. Attach a suitable temperature sensor to the front or back surface of the modules near the middle , if more than one module of the same type are tested simultaneously, it will suffice to monitor the temperature of one representative sample
2. Install the modules at room temperature in the chamber
3. Connect the temperature -monitoring equipment to the temperature sensors, connect each module to the appropriate current supply by connecting the positive terminal of the module to the positive terminal of the power supply and the second terminal accordingly. During the thermal cycling test set the continuous current flow during the heat up cycle to the technology specified current at temperature from -40℃ to 80℃, during the cool down , the -40℃ dwell phase and temperatures above 80℃ the continuous current shall be reduced to no more than 1.0% of the measured STC peak power current to measure continuity, if the temperature rises too fast (greater than 100℃/h) at the lowest temperature , the start of the current flow can be delayed until the temperature has reached -20℃
4. Close the chamber and subject the modules to cycling between measured module temperature of -40±2℃ and +85±2℃, the rate of change of temperature between the low and high extremes shall not exceed 100℃/h and the module temperature shall remain stable at each extreme for a period of at least 10min. The cycle time shall not exceed 6 hours unless the module has such a high heat capacity that a longer cycle in required
5. Throughout the test, record the module temperature and monitor the current flow through the modules
