Universal Stiffener with Mounting Rivet

The Universal Stiffener™ is an aluminum bar that functions as a mechanical printed circuit board (PCB) stiffener, a heat transfer device or an electrical bus bar.     

The typical construction for a PCB stiffener is a rectangular bar with drilled and tapped holes.  Most PCB stiffeners are just that, but drilling and tapping holes in a bar is expensive.  The Universal Stiffener with rivet mounting, reduces this expense with design that will accept a rivet anywhere along its length. 

PCB Stiffener with Mounting Rivet

The rivet can be inserted anywhere along the entire length of the stiffener.  The rivet length is determined by the total grip of your configuration.  The grip = dimension "C" plus the washer thickness plus the PCB thickness plus the insulating spacer height.
