DEK Fine Grain stencils
DEK Fine Grain stencils can be used with the DEK Mesh-
mounted frames, DEK VectorGuard
TM
Classic and DEK
VectorGuard
TM
High Tension frame systems. Fine grain stainless
steel stencils provide smoother laser-cut aperture walls for
improved paste release and better material transfer efficiency.
A cost-effective alternative to nickel, fine grain stainless steel is
ideal for challenging dimensions and high-density assemblies.
Achieving a finer grain of stainless steel, DEK Fine Grain stencils
provide superior paste release and a smoother stencil surface.

DEK Multi-level stencils
Ideal for ensuring optimized solder paste height and volume for components that are
distributed over a wide area, DEK Multi-level (step) stencils are produced with the latest
micro-milling technology to ensure exceptional accuracy and repeatability.
DEK Multi-level (step) stencils are available in stainless steel
or nickel and are ideal for printing paste on SMT boards with
ne pitch parts arranged over a large area. These stencils
provide excellent print performance for applications with micro
BGAs,
0.3 mm QFPs and small components such as 0201s metric, as
well as packaging applications and release of specialty solder
paste formulations
Multi-level stencils are available mesh mounted onto industry-
standard frames and are available for the DEK VectorGuard™
Classic and DEK VectorGuard
TM
High Tension frame systems.
Benets:
■ Flexible local adaptation to any component mix
■ Maximum positioning accuracy
■ Improved solder paste homogeneity
■ Improved repeat accuracy thanks to extra-smooth surface
structure and high-precision edges
■ Minimized paste wastage through optimized surface structure
■ Significant reduction of paste residue in shadow areas
■ Flexible design of pressure-sensitive areas
■ Significant squeegee pressure reduction thanks to a modified
ramp profile
