Provided are an optical printed circuit board and a method for manufacturing the same. The method comprises processing a workpiece using a processing tool, receiving trace data associated with the processing of the workpiece from the processing tool and determining at least one value associated with a health of a portion of the processing tool based on at least a portion of the received trace data. The transverse members of the first and second offset support members are coupled together and are laterally adjustable with respect to each other. The first electrodes and the second electrodes are alternately arranged along a first direction. The attachment means consists of a rearwardly facing arm on the sunglasses to which a magnet is affixed, at each location, and magnets affixed on the eyeglasses in alignment with the magnets on the sunglasses.
