Reliability Testing

Simulated Reflow (Without Solder)

 N/A Samples for qualification testing require 3 passes 260 ±5 ºC reflow solder profiles. 2 hours of setting time is required between each reflow profile test.

Static Humidity

 N/A Precondition at +25 ºC for 1 hour. Expose to +85 ºC with 85% relative humidity for 1000 hours. Finally, dry at room ambient for 3 ±1 hour before taking final measurement.

Temperature Shock

 N/A Each cycle shall consist of 30 minutes at -40 ºC, 30 minutes at +125 ºC with 5 minutes transition time. Test duration is for 30 cycles, starting from cold to hot temperature.

Electrostatic-Sensitive Device (ESD) Sensitivity

 N/A Perform ESD sensitivity threshold measurements for each contact according to MIL-STD-883G, Method 3015.7 for Human Body Model. Identify the ESD threshold levels indicating passage of 8000V Human Body Model.

Vibration Test

 N/A Vibrate randomly along three perpendicular directions for 30 minutes in each direction, 4 cycles from 20~2000 Hz with a peak acceleration of 20 Gs.

Drop Test

 N/A Drop samples from 1.5 m height onto a steel surface, total 18 times and inspected for mechanical damage.

Shock Test

 N/A Subject samples to half-sine shock pulses (3000 ±15 % Gs for 0.3 ms) in each direction, for a total of 18 shocks.

Operation Life

 N/A Subject samples to +125 ºC for 168 hours under full maximum rated voltage
