Global Stencil,
Inc. utilizes the latest laser technology. Laser cut stencils
are the most widely used and accepted method of stencil application
today. Smooth, trapezoid shaped sidewalls offer the cleanest print and
release of paste and are perfect for printing ultra-fine pitch, BGA and
micro-BGA openings.

Laser
cut apertures can be cut to an accuracy of +/- .00025" and the typical
laser cut aperture is .0005" smaller on the top, or squeegee side, of
the stencil than the bottom, or contact side, of the stencil. This
trapezoidal aperture shape permits optimal paste transfer from the
stencil.
With 5 laser stencil cutting systems in operation, Global
Stencil stays ahead of daily stencil demand.

The T8 Stencil Production System
is our latest laser cutting system and was installed the first quarter
of 2008. It is the result of over 25 years of laser design and it
is the laser stencil system with the very best cut quality in the market
today. Achieving this cut quality
requires
an optimal balance of laser quality, motion control and gas delivery.
The new fiber laser system used on the T8 can deliver kerf widths
as low as 0.015mm. The T8 is the only laser stencil machine which can
deliver the required smooth and precise motion and uniform gas delivery
necessary to match the fiber laser technology. No other stencil machine
can boast a resolution of 10nM and an effective laser beam down to 15
microns! In addition to its extremely smooth aperture walls, the
T8 is the fastest laser available in the industry. With the
ability to cut up to 28,000 apertures per hour, this system allows us to
deliver very large aperture count stencils next or same day, something
impossible with older generation laser cutting systems.
Our Lumonics Screencut
stencil cutting systems have been workhors es
and continue to perform in our daily stencil operations. The YAG
lasers produce extremely smooth sidewalls and maintain amazing accuracy.
Global Stencil's commitment to preventative maintenance and laser tuning
and adjustment allow these machines to continue to perform. When
combined with new fine grain stainless steel alloys, these systems
produce stencils capable of printing micro BGA's, 0402's and have even
produced stencils printing 0201's. The combination of the latest
stainless steel technology and these laser systems have eliminated the
need to polish after laser cutting and continue to serve the needs of
our industry.
