The ProVia-H workstation models
utilize the production-proven hybrid processing approach. The UV
laser is first used to drill openings of the required size in the top
copper foil. This process is followed closely with an RF-CO2
laser to drill the exposed dielectric. The copper of the stop pad
will reflect the CO2 light,
permitting aggressive drilling of even the toughest materials (e.g. high
glass content, high Tg FR4) without damage to the stop pad.

 ProVia data
sheet
Laser drilling of microvias is now commonplace in the electronics packaging
industry, allowing high density circuits to be made for a range of
products from cellular phones and other hand-held devices to chip on flex, multi-chip modules,
and PCMCIA cards.
The ProVia drillers
provide the
ultimate processing workstations for rigid boards, with high performance galvos
for rapid point-to-point drilling and precise control for fine features.
The CO2
laser is appropriate for high speed machining (drilling, cutting and
skiving) of dielectrics, while the UV laser is able to machine copper and
provide higher cut quality in many dielectrics. An optional second
galvo head for CO2
-only or UV-only systems can increase
drilling speeds up to 2X over the standard single-head configuration.
Whether your application is with glass- and aramid-reinforced epoxies or
non-reinforced materials (e.g. resin-coated foil), there is a ProVia model
to meet your requirements.
