ABSTRACT:
A light table work station is provided for use in combination with a transparent prototype circuit board. At least a portion of each circuit trace on a circuit board is viewable when the board is populated with components, and back lit when the board is positioned on the work table, and each trace is also accessible from each side of the circuit board for examination, testing and/or modification. A work station is provided with a second upstanding light table for retaining transparent artwork sheets, each sheet bearing a copy of the circuit traces for each respective circuit plane on the circuit board.
