SMT Solder Paste Printing Squeegee 300mm for GKG Stencil Printer screen printing

Product Specification

1. Product Overview

The SMT Solder Paste Printing Squeegee (300mm) is a precision consumable component designed for SMT stencil printing machines, with primary compatibility for GKG solder paste printers and extended support for other leading brands such as YAMAHA, DEK, and MPM.

In SMT production, stencil printing is widely recognized as the most critical process step affecting solder joint quality and overall assembly yield. The squeegee blade plays a decisive role in controlling solder paste rolling behavior, stencil aperture filling, and excess paste removal.

This product is engineered to deliver stable, repeatable, and high-precision printing performance, making it suitable for both high-volume mass production and high-mix manufacturing environments.

2. Primary Application

This squeegee blade is widely used in:

• GKG automatic solder paste printing machines

• SMT PCB assembly production lines

• Fine-pitch and high-density PCB printing

• Electronics manufacturing facilities requiring stable and consistent print quality

3. Importance of Squeegee Performance in SMT Printing

During the stencil printing process, the squeegee blade performs the following essential functions:

• Rolling solder paste evenly across the stencil surface

• Applying controlled pressure to fill stencil apertures

• Removing excess solder paste to maintain a clean stencil surface

Any deviation in blade geometry, stiffness, or edge condition can lead to printing defects such as insufficient solder, bridging, smearing, or inconsistent deposit volume.

4. Material & Manufacturing Quality

All squeegee blades supplied by SMT PARTS SUPPLY LTD are manufactured using industrial-grade materials suitable for continuous SMT operation.

Key quality characteristics include:

• Consistent straightness across the entire blade length

• Uniform thickness and stiffness

• Precision-finished blade edges

• Resistance to wear during repetitive printing cycles

These characteristics ensure stable pressure distribution and predictable printing results.

5. Standard Length & Custom Size Capability

While 300mm is one of the most commonly used sizes for GKG stencil printers, different machines and PCB sizes require different squeegee lengths.

We offer both standard and customized squeegee blade lengths, including but not limited to:

• 200mm

• 250mm

• 300mm

• 350mm

• Other lengths available upon request

Custom sizing helps ensure optimal contact area and uniform pressure across the stencil surface.

6. Extended Compatibility with Multiple Printer Brands

In addition to GKG stencil printers, we are able to supply high-quality squeegee blades for other mainstream SMT printing machines, including:

• YAMAHA SMT stencil printers (e.g. YCP series)

• DEK stencil printers

• MPM stencil printers

• Other automatic or semi-automatic SMT printers

Each squeegee is selected or customized based on machine holder structure, pressure mechanism, and printing characteristics.

8. Printing Performance Advantages

Using a properly specified squeegee blade provides:

• Stable solder paste rolling behavior

• Improved aperture filling consistency

• Reduced printing defects

• Better fine-pitch printing capability

• Lower stencil cleaning frequency

These advantages directly contribute to improved first-pass yield (FPY).

9. Installation & Setup Guidelines

Recommended installation practices include:

• Ensure blade edge is clean before installation

• Fix blade evenly in the holder

• Adjust squeegee pressure according to stencil and paste type

• Verify blade contact angle before production

Correct setup is essential for maximizing blade performance.

10. Wear Characteristics & Service Life

Squeegee blades are consumable components and experience gradual wear due to:

• Friction against the stencil surface

• Contact with solder paste particles

• Repetitive mechanical stress

Visible edge rounding or printing instability indicates it is time for replacement.

11. Preventive Maintenance Philosophy

Replacing squeegees according to a defined schedule helps maintain stable printing quality and avoids sudden process fluctuations.
