◆RELIABILITY TEST
OPERATING LIFE
Subject samples to room condition for 96 hours with rated voltage .
TEST IN HIGH TEMP
Subject samples to +60℃ and operate for 96 hours with rated voltage .
TEST IN LOW TEMP
Subject samples to -20℃ and operate for 96 hours with rated voltage .
STATIC TEST
Precondition at room temperature for 1 hour .Then expose to +40℃ with 90 to 95% relative humidity for 96 hours .Finally dry at room ambient for 2 hours before taking final measurement.
TEMP CYCLE TEST
Each temperature cycle shall consist of 30 minutes at -30℃,15 minutes at +20℃,30 minutes at +60℃ and 15 minutes at +20℃. Test duration is for 10 cycles. Components must be fully stabilized at temperature extremes before data is taken, which may require up to a 2 hours soak.
ANDOM TEST
Secure samples .Vibrated randomly 10Hz～30Hz～10Hz with 0.75mm peak amplitude and 30Hz～55Hz～30Hz with 0.15mm peak amplitude. The test duration is 30 minutes per plane.
MECHANICAL SHOCK
Secure samples as required. Then subject samples to half sine wave pules (100m/s2 for 16ms)for a total of 1000±10 shocks.
DROP TEST
Drop samples with package naturally from the height of 0.8m onto a wooden board six times
