ALPHA® FORM
Electroformed Stencils are designed and manufactured
to give the ultimate stencil printing for the most
challenging surface mount requirements, particularly
when used in conjunction with ALPHA® Solder
Pastes. The stencils are manufactured using 100%
solid nickel plating (electroforming process) resulting
in high precision durable stencils of any custom
thickness.
FEATURES & BENEFITS
High
Repeatability: ALPHA® FORM Stencils
are made using anytime the exact same manufacturing
standards in order to deliver consistent performance
by eliminating the two sources of variation through
our Stencil Engineering System, ALPHA DIMENSIONS™:
• Design Inconsistencies
• Manufacturing Inconsistencies
High Precision: Produced from the modified CAD/CAM data
in a climate controlled clean room using state of the art processing
tools at 10.000 DPI resolution, resulting in a Aperture Size Accuracy
of ± 0.5 mil (± 12.5 micron) with superior processing capability
(CpK ≥ 1.33).
Ultimate Durability: Hard Nickel stencils (> 500
VH) provide typically twice the lifespan of stainless steel stencils.
Ultra Fine-pitch
Printing: ALPHA® FORM
Electroforming technology
is targeted for print
applications of 20 mil
(0.5 mm) pitch and below
and all area array packages
(Flip-chip, CSP’s, μBGA’s,
BGA’s and CCGA’s)
as well as 0201 component
technology.
Predictable Printing
Results: Proprietary
internal testing provided
us with the science behind
the printing. Our database
with more then 12 million
data points allowed us
to quantify the effects
of taper, surface finishes,
positional accuracy and
area ratio. This information
is used in our best practice
commonality program to
ensure consistent and
predictable print results.
Print Performance: In
addition to the ability
to provide local stepped
area’s on the stencil,
the ALPHA® FORM process
can manufacture any optimized
custom thickness for
optimum paste transfer
volumes. A special in-process
sloped ‘Stepless
Step’ can be created
on the PCB side of the
stencil in those area’s
where large solder deposits
are required.
