ALPHA ® Stencils
Helping you get
right-first-time
paste deposits
through advanced
stencil services
and technology
The Complete Stencil Solution ALPHA® Stencil products are based
on unique blends of advanced
technology, the experience gained
from having made over half a
million solder paste stencils and the
specialist knowledge that could
only be accumulated by a company
privileged to produce both solder
pastes and printing stencils… All
combined with a genuine will to
meet your most stringent delivery
expectations.
With over of 250 man-years of CAD
experience and 400 man-years of
manufacturing experience globally,
Cookson Electronics has the power
to “know what works” and the
global, multi-site manufacturing and
quality systems to deliver it.
Knowledge
Service
Cookson Electronics has an intimate
knowledge of the stencil printing
process, based on its global
experience as the leading producer
of stencils, as well as advanced
solder paste products worldwide.
If you need it tomorrow, order it
today and we'll do everything
humanly possible to meet your
needs… And we'll keep you
informed all the way down the line.
Expertise through Experience
Cookson Electronics has a wealth of
design and manufacturing expertise.
Our CAD technicians combine Alpha®
design and modification rules, honed
by customer feedback and
experimental development, with your
own specific design requirements
and preferences to produce stencils
that are “right first time”.
ALPHA® Stencils are available as
framed or frameless foils to suit all
printers and formats.
ALPHA® CUT Laser Cut Stencils
To ensure that your stencil is 'right
first time' we analyse the data you
provide to ensure its print capability.
We calculatie the area ratio and
transfer efficiency for each aperture,
allowing us to highlight potential
problems at the pre-production
stage.
Meeting today's challenging
printing requirements with fast
response, high accuracy, excellent
printing performance and
worldwide availability.
• Leading technology products
• Continuity of supply ensured through multiple manufacturing sites
• Delivered lowest cost of ownership

Nickel Stencils
ALPHA® NICKEL-CUT™ Laser Cut
Nickel Stencils
The highly repeatable, accurate
printing performance you require
from the company that pioneered
stainless steel, laser stencil
manufacturing technology.
State-of-the-art ALPHA® FORM™
electroformed stencils provide high
accuracy, durability, and long life for
high volume printing applications.
State-of-the-art ALPHA® NICKELCUT™ stencils are hybrids, that
combine the durability of
electroformed nickel stencils with
the fast availability of laser cut
stencils.

ALPHA® INSPECT™
Optical Inspection Masks
ALPHA® TetraBond™ is the culmination
of “frameless” stencil development; an
elegantly simple system that enhances
foil rigidity making safe mounting and
demounting an easier proposition.
Alpha® Repair™ are mini and micro
rework stencils, for the controlled,
localised printing of solder pastes
when reattaching single components,
particularly BGAs, µBGAs, PLCCs,
QFNs and QFPs to circuit boards.
Available for 'board print', 'print on
component' and component repair'.
Alpha® Inspect™ cover stencils are
laser cut masks, designed to fit over
populated boards to assist manual
inspection and may be used to
enhance AOI efficiency.
• Excellent rigidity for durability and
ease of use
• Safe to use, no sharp edges
®
• Available with all Alpha stencil
technologies
• Image float (associated with mesh
mounted stencils) is eliminated
• Minimal storage space requirement

ALPHA® SQUEEGEE™ Blades
A range of high precision, metal
squeegees to suit all popular print
machines and squeegee holders.
Alpha® Squeegees™ are designed to
ensure optimum aperture fill by
encouraging 'paste roll', while
minimising topside paste smearing
on the stencil.

optimise print performance
ALPHA® INSPECT™… Enhancing
optical inspection efficiency
ALPHA® STEP™ Multi-level Stencil
Technology
Alpha® Step™ Multi-level, Step
Stencil Technology is available on all
ALPHA® stencils and offers the SMT
engineer significant flexibility in
achieving the right solder paste
deposit for devices with markedly
diverse paste volume requirement.
They can provide additional paste
height in selected areas of the PCB
(step-up stencils) or reduced height
deposits in other areas (step down
stencils).
Where a board has raised areas that
would hamper the ability of the
stencil to perform to its optimum,
contact side relief cavities can be
incorporated in the PCB side of the
stencil to overcome the problem.
(step relief cavity stencils).
