Abstract
A planar generally rectangular, multi-edge extender board has a plurality of spaced terminals along adjacent edges thereof or along three or four of its edges. Each of the edge terminals is coupled by means of a conductor to either a terminal on an opposed edge of the extender board or to a multi-pin connector mounted to an inner portion of the extender board. The edge terminals of the extender board are adapted for insertion in and coupling to either a connector in an equipment rack in which the circuit board is used or direct coupling to the circuit board itself. The multi-pin connector allows the edge-mounted terminals of the extender board to be coupled via a multi-conductor ribbon cable to corresponding edge terminals of a circuit board removed from the equipment rack. The extender board allows for complete testing of a thus removed circuit board having terminals on two or more adjacent edges as well as on both sides thereof without modifying either the circuit board or the equipment rack in which it is installed. Following circuit board testing, the extender board is removed from the equipment rack permitting re-installation of the circuit board into its in-service position. …
