摘要： An apparatus and method for rigidly stabilizing or restraining circuit boards is provided. The apparatus has a rigid cross member (20) and a circuit board clamp (10). These provides stabilization of commercial off the shelf (COTS) circuit boards for use in harsh environments. A one piece clamp has hooks with notched ends that attach to opposite sides of each circuit board. The clamp has a surface parallel to the hook. The parallel surface has threaded holes. Threaded shafts are used with the threaded holes to contact the clamp hook and provide pressure on the printed circuit board. A threaded hole is used with a threaded shaft to engage a rigid cross member. The cross member has unthreaded holes to allow for attaching to the clamps with threaded fasteners. The rigid cross member is then attached to the chassis with a fastener. This eliminates flexing of the circuit board under vibration.
