Abstract
A method of ablating fluoropolymer composite materials is presented wherein it has been found that small holes (less than 100 .mu.m) can be formed in fluoropolymer composite laminate materials using UV lasers. The resulting holes can be used to produce vias and plated through-holes having smooth side walls with little or no debris or residue remaining in the holes and minimal damage to the polymer. Thus, the vias and plated through-holes can be plated without further cleaning processes. In addition, the holes are formed at a relatively fast rate.
