Test requirements

1, high-temperature test: the product in the ambient temperature (70 +2) ℃ laboratory box shelved 4h, after the end of the appearance, structural process, electrical performance should be no abnormalities with the test before and can work properly

2, low-temperature test: the product in the ambient temperature (-25 ± 3) ℃ test box shelved for 4 hours, after the end of the appearance, structural processes, electrical performance should be no abnormalities with the test before and can work normally

3, constant temperature heat and humidity test: the product in the ambient temperature (40 ± 2) ℃, humidity 93% ± 3% test box shelved for 48 hours, after the end of the appearance, structural processes, electrical performance should be no abnormalities with the pre-test and

Normal work

4, neutral salt spray: PCBA is not energized, vertical, placed in the salt spray box, solution concentration: 5%, temperature 35 ℃, a total of 192 hours of testing After the end of the appearance, structural process, electrical performance should be tested with the

No abnormality and can work normally Power consumption deviation ≤ 20% can be received, lamp beads, terminals, connectors and wires are not bad as a criterion for this test.
