A CO(2) circulating gas laser, rated at 1.2 kW, and continuously discharging infrared laser radiation at a wavelength of 10.6 Mum, is used to cut multilayer "unfired" ceramic substrates. The laser beam has a diameter of 0.0254 cm (0.010 in.) and is stationary. The laminate, mounted on a vacuum chuck assembly, is indexed under the laser beam. The required substrate tolerances can be designed for X, Y dimensions and for feature to edge centrality.
