Abstract
An integrated circuit package comprises a package substrate (), an electrically insulating material () adjacent to the package substrate, and a mark () on the electrically insulating material. The mark is such that a visual contrast between the mark and the electrically insulating material is maximized when the mark and the electrically insulating material are exposed to coaxial illumination. In one embodiment the electrically insulating material over the package substrate has a first surface roughness and a mark on the solder resist material has a second surface roughness that is no more than approximately twenty times greater than the first surface roughness.
