Qualification Testing on Aerospace Connectors

DES recently performed qualification testing on aerospace connectors which involved combined temperature and sinusoidal vibration testing, random vibration testing and shock testing.  Combined temperature and sinusoidal vibration tests were performed per EIA 364-28F.  EIA 364-28F required test conditions of 10-2000 Hz, 20G maximum acceleration sweeps at temperatures of -54°C and 200°C over the course of 4 hours per axis.  Random vibration tests were also performed per EIA 364-28F.  Random vibrations at 50-2000 Hz, 46.3 Grms were applied to the connectors for 8 hours per axis.  The random vibrations were applied at room temperature.  Finally, the connectors were subjected half sine shocks per…

ASTM D7386-12 Package Testing

DES recently performed package testing per ASTM standard, ASTM D7386-12. 

Thermal Shock Testing – Temperature Cycling

Thermal shock testing also called temperature shock testing or temperature cycling exposes products to alternating low and high air temperatures to accelerate failures caused by repeated temperature variations during normal use conditions. The transition between temperature extremes occurs very rapidly during thermal shock testing, greater than 15 °C per minute. Alternatively, temperature cycle testing uses slower rates of change between high and low temperatures. The failure acceleration rate for thermal shock testing is determined by the Coffin-Manson equation as previously discussed in DES’s blog article Temperature Cycling Testing: Coffin-Manson Equation. Equipment with single or multiple chambers may be used to perform…

Case Study: Combined Temperature & Vibration Testing of Automotive Mass Air Flow Sensors

Mass Air Flow Sensors (MAFS) are used to measure the mass flowrate of air entering engines in newer model cars. The mass air flow information is transmitted to the engine control unit (ECU) to balance and deliver the correct amount of fuel mass to the engine.  These sensors operate in a very harsh environment, a car engine compartment! Testing their reliability and proving their durability is a very difficult task. Mass Air Flow Sensors (MAFS) Combined Temperature Vibration Testing DES was awarded multiple contracts to perform combined temperature and vibration reliability testing of Mass Air Flow Sensors from various automotive…
