The rapid temperature change test is suitable for the safety test of electronic components, testing aerospace, electronic appliances, materials and various electronic components and other products under extremely fast temperature changes, then a test equipment before use, has its set of operating procedures, according to the process to operate, the final test results will be more accurate, so we must pay attention to this problem when testing, today Miki Technology will introduce to you the operation process of the rapid temperature change test.
First of all, before the test, we must check the inside of the box, whether the power supply is correctly grounded, whether the sealing of the box is intact, whether the water source inside the water tank is sufficient, and whether the electrical components are complete and damaged.
After turning on the power switch, it should be preheated for 30s and then the temperature and cooling test should be carried out, it should be noted that the temperature test should be done first and then the cooling test, the lighting can be turned on to check the test situation in the box, insulating gloves should be worn during the test, but also to prevent damage to the circuit by tensile force, after the test is completed in accordance with the specified time, the power supply should be disconnected first, and the temperature in the box is the same as the indoor temperature, then the test sample can be taken out from the box.
And it should be noted that after the test is completed, the surface of the box or the inside of the box should be maintained, and the box should be cleaned up in time to keep the box dry.
