Durability of COTS Modules in Tactical Fighter Environments


The ability of COTS electronic modules to meet the environmental requirements of tactical fighter jets has long been questioned, with one of the primary concerns being vibration survivability. As a result, much of the electronics has been packaged using custom or pseudo-custom form factors. With the move to more open systems architectures, there is an opportunity to re-evaluate COTS modules to see how rugged they can be. Most suppliers of rugged COTS modules offer several grades of ruggedness for their products, from lab-grade air-cooled versions to base rugged conduction-cooled versions to highly rugged modules with enhancements to meet extended durability requirements. Examples of these enhancements include connector changes for high vibration and BGA underfill materials for thermal cycling. Modules built to the new VPX standards (VITA 46, VITA 48 and VITA 65) offer several advantages for open systems architectures in tactical fighter jet environments.
