CO2 Laser Machine/Drill/Scribe
This 1″x1″x.010″ alumina substrate shows the
intricate patterns generated by laser machining with a CO2 laser.
As well, thin cross sections can be produced. Also,
many designs incorporate
alignment features such as tooling hole and slot
for subsequent processing steps requiring precision,
but non-optical, alignment. This part is an imaging mask for
thin film printing.
Step and repeat arrays are widely used for
gaining production efficiencies during printing.
Laser work can be performed before and
after the printing steps.
The arrays can be laser scribed/scored for final separation.
CO2 lasers are well suited to machining and profiling
ceramic substrates for electronics.
This is where Laser Machining Services became widespread and therefore helped integrate new materials into electronics.
The CO2 laser is especially powerful for shaping substrates as well as adding through holes into electrically
insulating materials that will be used as circuit boards. This is particularly true for high reliability materials used in Military and Space applications.
