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.

The Universal Stiffener is an aluminum extrusion alloy 6063-T6 available in two finishes:
Finish must be specified upon ordering.
* Optional insulating hardware is available in packs of 100, 500 and 1,000.

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.
