Abstract

A rigid bar of material is fastened to a circuit board to increase its stiffness. The bar is preferably a high modulus plastic such as liquid crystal polymer. Flexible fingers which surround a central opening are formed integrally with the bar and pop into throughbores in the circuit board. Each finger has at least one arcuate protrusion and, preferably several, which can engage the bottom of the circuit board. A rigid pin which may be made of steel is slid into the central opening and has an interference fit therewith to hold it in place to prevent flexible fingers from moving inwardly so the stiffener is held fast to the circuit board.
