The PC/104+ board stacking connector utilizes the unique Hypertac contact system. The Hypertac contacts improve the performance of the PC/104 platform by providing immunity to shock and vibration fretting and allowing for matched impedance and better signal integrity. The capabilities of the ruggedized PC/104+ exceed all prior requirements for the form factor. Its traditional stackable design eliminates the need for backplanes or metal card cages. The PC/104+ is interchangeable with other PC/104+ “commercial off-the-shelf” (COTS) products and provides engineers with a shock and vibration resistant interconnect solution for their applications.
