Abstract
A single beam of radiation is split and part of the beam is directed to conductive links, e.g. runners on a substrate. Analysis of the incident beam and the beam reflected from the substrate permits a determination of when the link is blown and rendered non-conductive and when significant substrate involvement occurs.
