Precision Laser Machining of Ceramic Substrates Used in Microelectronic Devices
Featuring Nd:YAG Solid-State Lasers
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 is laser “zapping” through a metal layer on top of the ceramic. A metalized surface, gold for example, is easily cut through or scribed. The gold coating actually assists laser removal rather than being reflected as is the case with CO2 lasers.
Laserod cuts, slots and drills ceramic, as shown below.
