PCB Retention, Extraction and Cooling Components

PCB Wedge Loks / Card Loks

Designed to retain PCBs in rugged, heavy shock and high vibration environments commonly found in Military and Defense and commercial aerospace systems. In addition to PCB retention, Card Lok and Wedge Loks also aid in thermal transfer from the PCB to the cold wall via conduction, by improving the interface between the PCB and the chassis rail.

Conduction Cooled Assemblies - Heat Frames

Conduction Cooled Assemblies consist of a conduction-cooled frame, backing plate or backing strips, extractors and wedge clamps. They are designed for circuit boards requiring cooling in severe environments where convection cooling is not practical. The assembly also provides needed structural support of the plug-in module during extremely high-shock and vibration applications.
