Elma Electronic Inc. (Fremont, CA) has introduced a ruggedized ATR chassis for MicroTCA. The MicroTCA chassis is an ARINC 404A Full- Size ATR Long Enclosure, often used in commercial and military aviation. The rugged enclosure features modified front panels that can be secured to the chassis, providing more protection for shock and vibration. Shock absorbers/dampers can also be added to the enclosure for extra protection. Thermal management can be achieved via either convection or conduction-cooling.

The chassis meets the MIL-STD-810E shock/vibration requirements and MIL-STD-461 for electromagnetic interference. The vibration and shock tests were performed according to the IEC 61587 1 and VITA 47 standards in six axes (three spatial axes, with the system rotated by 180 degrees for each axis). The backplane holds six AMCs, one MCH (MicroTCA Carrier Hub), and one power module. Single module slots in the full size are standard, but other configurations are possible with the enclosure's modular design.
