Temperature Loop Test Instrument/Technical details:
1.Objective: accelerated stress accelerated life test test test environmental stress screening (ESS)
Test standard :
MIL-STD-202;Method107;IEC60749-25;JEDECJESD22-A104-bIEC68-2-1;MIL-STD-2164-85
2.Test method: temperature impact test temperature cycling test
3.Test environment: the environment more than the use of harsh environment limits
4.Sample : spare parts and components , solder joints (BGA, CSP) Finished
5.Sample size: small large
6.test temperature range : -40 (-55) ~ 125 (150) celsius degree , -40 (-65) ~ 125 (150) celsius degree , -40 (-0) ~ 100 celsius degree
7.Studio Size: the box size W*H*D600*850*800cm
8.MEAS W*H*D1200*1700*1300cm
Temperature change rate:
1.bath method : more than 30 celsius degree / min ( air )
2.bath method : more than 50 celsius degree / min ( air )
3.bath method : less than 15 celsius degree / min ( sample )
4.bath method : less than 20 celsius degree / min ( air )
Cyclical Temperature Instrument/Acceleration factor:
1.100 ~ 500 times
2.accelerated test acceleration factor smaller than 10 to 20 times
3.Test result: production quality difference verify design information
Temperature Circulate Instrument/Temperature Shock Test :
1.heating / cooling rate of not less than 30 celsius degree / min . Large temperature range , and also increases the test severity changes in the rate of temperature increase .
2.difference in temperature shock test and temperature cycling test is primarily different stress load mechanism . Mainly on the temperature shock test due to creep and fatigue damage cited
Lapse , but mainly on the temperature cycle fatigue failure due to shear caused .
3.temperature shock tests allow the use of two -slot test device ; temperature cycle test using a single-slot test device . In the second slot cabinets , temperature change rate to
Greater than 50 celsius degree / min.
4.cause temperature shock : reflow, drying , reprocessing, repair and other manufacture, repair process drastic temperature changes .
5.accelerated stress test: accelerated test using accelerated testing in a real environment is more than a short time , the test sample , in order to investigate the failure mechanism .
6.accelerated test method is used to increase the stress test samples fail to promote in the short term . However, care must be taken to avoid stress failure mechanisms other causes .
Temperature cycle test .
