A project was sanctioned by CSIR for the establishment of laser micromachining facility for ceramic substrates under facility creation category. Accordingly, the laser micromachining facility was created in the surface engineering division of CSIR-NAL for developing
Amperometric oxygen sensor for pilot life support system,
Ceramic substrates for space electronics
Solid oxide fuel cell and.
Automobile oxygen and NOx sensors by high temperature co-fired ceramics.
All these activities require precise machining of dense/ porous ceramic substrates. Four technology transfers have been realized till date.
The facility is an ideal tool ;Comic Sans MS";fofor cutting, scribing and drilling of ceramic substrates up to 2 mm thickness.
