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