ASM Squeegees
The integrity of the squeegee blade in the solder paste printing operation is
essential to optimal material deposition. ASM ensures its DEK squeegee blades
are manufactured to exacting standards for maximum lifetime and excellent in-
use performance.
Squeegee characteristics including blade material, exibility,
angle of attack and mounting mechanism have a signicant
eect on printing process control. Aligning the proper
squeegee to the application is made more simple with ASM’s
comprehensive range of polyurethane and stainless steel
blades, bonded or clamped mounting options and choice of
45° or 60° printing angle.
DEK Polyurethane squeegees
Polyurethane squeegees satisfy single thickness or multi-
level (step) stencil applications. The hardness of the
squeegee is dependent on the stencil construction: choose
harder squeegees (97 durometer and above) for durable, low
abrasion performance with single thickness stencils and a
softer squeegee (70 to 94 durometer) for multi-level stencils.
Available in hardness ranges up to 120 durometer, DEK
Polyurethane squeegees are manufactured of the highest-
quality material and can be re-ground to maintain a sharp
edge throughout the squeegee lifetime. DEK Polyurethane
squeegees are also available for DEK PumpPrint
TM
/ Adhesive
stencils, mesh and emulsion screen printing applications.
Stainless steel squeegees
The most widely used for SMT printing with metal stencils,
particularly for heterogeneous assemblies, DEK Stainless
Steel squeegees are well-suited for applications that feature a
mix of large, standard and ne-pitch components or in cases
where PCB panel atness cannot be conrmed. The wider
pressure window of DEK Stainless Steel stencils provides
excellent consistency and minimal wear.
DEK Stainless Steel metal squeegees are available with two
dierent angles and overhangs (free moving plate length
without support of the squeegee holder) to enable dierent
aperture paste lling requirements. The standard recommended
angle is 60° for a normal paste lling of the apertures, while
an angle of 45° will add more pressure to ll the apertures for
paste-intensive applications such as pin-in-paste.
Bonded / clamped mounting mechanisms
Mounting options for DEK Squeegees include bonding
or clamping. The mounting selection should take into
consideration the specic application, squeegee type and
printing operation. Clamping allows squeegees to be easily
interchanged and adjustments to blade exibility and durometer
to be made based on application requirements.This mounting
method is particularly well-suited for stainless steel and
composite blades.
Bonded squeegee assembly guarantees blade straightness for
high durometer polyurethane blades and allows exploitation of
the squeegee’s process advantages.
