Precision Laser Machining of Ceramic Substrates used in Microelectronic Devices

by Nd:YAG Solid-State Lasers

Laserod laser machines ceramic substrates. Tolerances to a few microns can be attained. But the most remarkable thing about our laser is its narrow kerf of 1 mil (25 microns) or 10 microns on special order.. Another useful capability we have is laser "zapping" through a metal layer on top of the ceramic. A metalized surface, gold for example, is easily scribed over. The gold coating actually assists laser removal.

Laserod cuts, slots and drills ceramic, as shown below.
