The DEK solder paste printer machine’s DEK clean rubber is critical in maintaining stencil cleanliness and print quality.
Here’s a detailed overview of the clean rubber feature in DEK solder paste printers:
Purpose:
The clean rubber system is designed to clean the stencil surface effectively. This ensures that any excess solder paste, debris, or other contaminants are removed, maintaining the integrity of the printing process and preventing defects in the printed circuit boards (PCBs)
Spare parts:
Clean Rubber: the main component, usually made of durable, flexible materials, can be attached to the template surface to remove contaminants
Vacuum system: usually integrated with a rubber blade to help remove debris and solder paste from the template.
DEK 191088 Solvent Pump Alcohol Gotec EMX 08 T/C 111895: this unit applies a cleaning solvent to the surface of the stencil to help remove stubborn solder paste residues.
Operation:
The clean rubber blade sweeps across the stencil surface during or after the print cycle.
The vacuum system and solvent dispenser work together to ensure thorough cleaning, including dry, wet, and vacuum-assisted cleaning modes.
This process can be automated and scheduled at regular intervals or triggered manually based on the operator’s discretion.
Benefits:
Improved Print Quality: Regular cleaning of the stencil ensures that the apertures are free from blockages, resulting in consistent and precise solder paste deposition.
Reduced Downtime: Automated cleaning reduces the need for manual intervention, minimizing production interruptions.
Extended Stencil Life: Proper maintenance through regular cleaning extends the life of the stencil, reducing replacement costs.
Defect Reduction: Clean stencils reduce the risk of defects such as solder bridging, insufficient solder joints, and other print-related issues.
Maintenance:
Regular inspection and replacement of the clean rubber blade are necessary to maintain its effectiveness.
Ensuring the vacuum system and solvent dispensers are functioning correctly and are free from blockages is crucial for optimal performance.
