An inspection board enables an inspector to accurately scan back and forth in both X and Y motions without having to take his eyes off an inspected workpiece or having to take his hands off the control handles for causing the scan. In some embodiments, an antistatic covering protects the workpiece against static charges which might otherwise build up as a result of a rubbing together of parts during the scanning motion. The inspection board has a particularly important utility when used to inspect printed circuit boards.
