chip creep

(hardware)Gradual loosening of an integrated circuit("chip") in its socket as a result of expansion andcontraction during the normal heating and cooling cycles of anelectronic system, combined with vibration, e.g. due tocooling fans. The chip can loosen to the point that poorelectrical contact between chip and socket reduces the signalquality, causing failure. Pushing chips back into theirsockets can cure such symptoms temporarily. Permanentsolutions include soldering chips directly to the PCB andclipping the component into the socket (as on some in-line memory modules.

The same phenomenon can affect anything plugged into a socketbut not held securely in place, e.g. a circuit board pluggedinto an edge connector on a motherboard or backplane cansuffer "card creep".
