VPX KNOWLEDGE BASE
VPX is a specification defining a rugged conduction-cooled system architecture for COTS military and industrial applications.

Extreme environments where VPX products are deployed require rugged modules and a hardened enclosure. The VITA 48.2 Specification defines a rugged, conduction-cooled system architecture for COTS military and industrial applications.

Under the VITA 48.2 / VPX Specification, the Conduction-cooled heatframe assembly (CCA) on the modules provide a thermal path from high energy components on the circuit board to the outer metal frame of the module. SolidWedge wedgelocks mounted on the heatframe serve to secure the module into the chassis cold-wall in order to withstand the necessary shock and vibration conditions. Force provided by the wedgelocks ensure firm contact between the module edges and the chassis slots in order to transfer thermal energy from the module to the enclosure in this conduction-cooled configuration.
