Squeegees

The integrity of the squeegee blade in the solder paste printing operation is

essential to optimal material deposition. ASMPT 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 signicant

eect on printing process control. Aligning the proper

squeegee to the application is made more simple with

ASMPT'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

/ 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 conrmed. The wider

pressure window of DEK Stainless Steel stencils provides

excellent consistency and minimal wear.

DEK Stainless Steel metal squeegees are available with two

dierent angles and overhangs (free moving plate length

without support of the squeegee holder) to enable dierent

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 specic 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.
