Patent abstract
A method of maintaining a circuit card in a card rack and a circuit card rack system are disclosed. A card rack including a laterally oriented clamping slot is provided. The clamping slot is at least partially formed from a temperature-contractible material. A circuit card having a clamped side region is provided. At least a portion of the clamped side region is inserted into the clamping slot. A predetermined temperature differential is applied to the clamping slot to reduce a longitudinal dimension of at least a portion of the clamping slot. A compressive force is exerted on the portion of the clamped side region which is located longitudinally within the clamping slot, via thermal expansion of the clamping slot.
