The second series of laser drilled wells form a tab which provides a more rigid tack to the substrate material thereby giving {HEAD ~ greater adhesion} of the substrate to the panel of substrate material, wherein {TAIL ~ the irregular shaped substrate} is retained in the panel of substrate material without breaking
