1.2 Performance Optimization

Dek Squeegee Blades feature a unique 60-degree primary angle of attack combined with an enhanced profile design that behaves like a 45-degree blade. This combination optimizes the rolling motion of the paste while maintaining excellent wiping characteristics, significantly reducing smearing issues.

For optimal performance, I recommend implementing proper pressure control. The Dek Squeegee Blades can achieve clean wiping with pressures as low as 0.144 Kgms per centimeter, preventing smearing while maintaining consistent paste transfer.

The metal Dek Squeegee Blades are particularly effective for fine-pitch applications, operating at lower pressures that prevent scooping and smearing. Their design allows for precise control of the paste bead, ensuring consistent material flow without the risk of paste climbing up the blade face.

To maximize smear reduction, manufacturers should maintain proper squeegee pressure settings around 500 grams per 25mm of blade length. This ensures clean stencil wiping while preventing paste bleeding and maintaining optimal print quality.

Claims:

• True: Dek squeegee blades reduce paste smearing by utilizing a specially designed blade profile that optimizes the paste transfer process, allowing for controlled paste deposition and minimizing the amount of paste that can “wick” up the blade, resulting in cleaner prints with less smearing, particularly when dealing with fine-pitch components on PCBs.
