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.
