This article describes an apparatus for making design changes on a circuit board or to repair a circuit board. Location of circuitry lines (conductors) laminated in circuit boards is done using the vias (through-board connections) as location points. The vias are produced on boards on a grid accurately positioned to accept electronic components. Using this via grid on the board one can locate specific vias and thus specific conductors laminated into the board. Changes are made to the board by drilling out conductors that use respective vias as pad sites and effectively relocating the pad or conductor by means of discrete wires added to the board. The apparatus shown in the figure is designed to locate the specific via for making the design change. The apparatus includes a motorized X-Y-Z Table 10.
