Abstract
The invention is a clamp for thermically clamping a circuit board module by its edge to spaced guide rails within an enclosure, the guide rails forming a channel for the module. In detail, the system includes at least one hollow closed off tube, filled with a fluid-like material, joined to the edge of the module, the at least one tube having a semi-flexible wall and a specific width and volume. A mechanism is mounted to the module for decreasing the volume of a portion of the at least one tube causing the remaining portion of the at least one tube to increase in width clamping the module between the guide rails.
