The ProVia-C workstation models utilize the production-proven
RF-excited CO2
lasers for high quality, high speed drilling of dielectric materials as
well as skiving and cutting applications. There are two main methods
of creating the hole sizes and shapes: using a conformal mask, or
using a focused laser spot directly. With a conformal mask
process, the holes are defined in the top copper layer by either a UV
laser (as in the ProVia-UV machine) or by a chemical etching batch
process. The CO2
laser flood exposes the opening, removing the dielectric without damage to
the surrounding copper or the stop pad. Direct drilling is typically
performed into plain dielectric using the so-called large window process,
or into green ceramic tape without pre-defined openings. These
processes use high
quality laser beam of appropriate diameter targeted at the via
location. In those cases with a copper stop pad, it 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.

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.
