The
application in micro-electronics industry of solid UV
Lasers:
With
the increasing demands of small electronic products
and micro-electronics components,the close processing
of polymer materials increasingly become one of the
fastest applied field in laser industry applications.UV
lasers are ideal instruments in dealing with plastic
and metal which is widely used in micro-electronics
components industry.
Laser
micro-processing:
Different
from infrared processing,UV micro-processing is not
"heat" processing essentially.It's easier
for most materials to absorb UV light than infrared
light,high-octane UV light photon directly destroy many
molecular key which on nonmetal surface,this "cool"
processing components has slick edge and minimally charry-melt
influence.
Due
to UV laser's merit in focus,focus dot can reach sub-micron,then
it can be superior to the micro-processing in metal
and polymer,can process small components;even if under
low-rise level of pulse energy,can get upper energy
density,process materials effectively.
Conclusion:
With
the development of UV semiconductor pump solid components
which has firmly structure and high power,directly use
laser to molding process circuit board and small components
has become attractive technic
