ABSTRACT:
A method for deposition of metals onto a workpiece by applying a sensitizing solution to a workpiece, directing a high intensity optical beam onto the sensitized workpiece surface to flash evaporate sensitizer from the workpiece in areas which are not to be plated, and thereafter contacting the workpiece with an electroless plating solution to deposit a layer of metal in those areas from which the sensitizer is not flashed off.
