Abstract
A method of calibrating a laser utilized in a laser element cutting system utilizing a mechanical gauge having pairs of metal pads formed in rows and columns on a substrate material. The height of the metal pads varies in each row with each column having the same height. The depth of the substrate material under the metal pads varies. The mechanical gauge is subjected to a laser cut process and the mechanical gauge is illuminated by a light source. The light shining through positions of metal pads indicates that the metal pad and the underlying substrate material have been cut. The depth of cut is determined from the thickness of the metal layer and the thickness of the substrate material that have been cut.
