Universal Stiffener with Mounting Screws

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 screw mounting, reduces this expense with design that will accept a screw anywhere along its length. 

PCB Stiffener with Mounting Screw

The screw thread is along the full length of the stiffener.  Mounting screws can be inserted anywhere along the entire length.
