Abstract: A circuit card assembly is provided for use in testing a system wherein the circuit card assembly employs a surface mount device such as a field programmable gate array. The circuit card assembly includes severable traces on a bottom surface of the assembly connecting pairs of near and far vias. The severable traces and the pairs of near and far vias allow the circuit card assembly to be selectively re-worked to accommodate changes to the design of the surface mount device. Hence, a new circuit card assembly need not be designed and fabricated each time the design or programming of the surface mount device is changed. The circuit card assembly includes a network of interconnection paths wherein each path to or from a pin terminal area of the circuit card assembly passes along at least one severable trace between at least one pair of near and far vias along the bottom surface of the assembly.

Abstract: A modular interactive connector unit is provided which has a base block with an array of male pins on one side and opposed female pins on the other side for interconnection between an electronic control assembly for an automotive engine and a wiring harness otherwise intended for direct connection to the electronic control assembly. The base block contains an array of contact points and adapter points which correspond with the control circuits in the electronic control assembly. Circuit completing electrical adapters from the adapter arrays on the base member support a board element having spaced apart arrays of adapter points for insertion of a circuit altering device in selected control circuits. A cap protects the board elements. The circuit altering devices alter the voltages read by the electronic control assembly to enhance performance of an engine.
