Revolutionizing SMT Stencil Printing Maintenance
The CN-600SM squeegee cleaning machine eliminates printing defects (insufficient solder, bridging, stencil clogging) caused by paste/flux residue. This eco-intelligent system replaces hazardous manual wiping and solvent soaking – resolving critical industry pain points:
- ✖️ Low-efficiency manual squeegee cleaning
- ✖️ Solvent health hazards
- ✖️ 30-50% solder paste waste
Operational Value for SMT Lines
✓ 30% printing defect reduction
✓ Zero solvent exposure (operator safety)
✓ 45% lower paste waste
✓ Fully automated squeegee maintenance
Ideal Solution For:
• High-mix SMT factories
• Zero-defect printing environments
• ISO 14001-compliant manufacturing
Product Features
Exceptional Cleaning Performance:
- Utilizes multi-frequency ultrasonic cleaning as its core technology, generating uniform and dense micro-bubbles that penetrate complex surfaces and gaps without dead angles. This effectively strips and emulsifies stubborn solder paste, adhesive, and flux residues. Cleaning efficiency and purity (>99%) far exceed manual wiping (60-70%) or solvent-only cleaning.
- Optional spray assist system provides “ultrasonic + spray” dual-action force, delivering stronger cleaning power for heavily soiled blades or special alloy squeegees.
Significant Operational Cost Advantages:
- Low Energy Consumption: Efficient design results in significantly lower unit energy consumption compared to high-pressure water jet or steam cleaning systems.
- Reduced Consumables: Dedicated eco-friendly cleaning fluid is reusable multiple times (~20-50 hours per kg). Combined with a precision filtration system that recovers precipitated solder paste, it drastically reduces solder paste waste (recovering approximately ¥2.2 worth of residual paste per cleaning cycle) and cleaning fluid consumption.
- Labor Savings: Fully automated operation replaces labor-intensive manual work. Comprehensive cleaning cost per squeegee blade can be as low as ~¥0.04.
Fully Automatic, Intelligent Operation:
- Integrated PLC control system and touchscreen HMI (Human-Machine Interface) enable intuitive and simple operation. Multiple cleaning programs can be stored and recalled (for different squeegee types and contamination levels).
- Automated process includes: Loading → Ultrasonic/Spray Main Wash → DI Water Rinse → CDA (Compressed Dry Air) Efficient Water Removal → Hot Air Drying → Unloading. The entire process requires no manual intervention.
Eco-Friendly, Safe & Ergonomic Design:
- Eliminates Solvent Hazards: Primarily uses water-based eco-cleaning fluid or DI water, avoiding the pungent odors and health risks (skin/respiratory) associated with traditional organic solvents, creating a healthier and safer work environment.
- Enclosed Cleaning & Filtration: Equipped with a filtration and recovery system that effectively collects residues (including recyclable solder paste), reducing environmental pollution and meeting modern factory environmental standards.
- Robust Construction: Main structure made of SUS304 stainless steel, offering corrosion resistance, acid/alkali tolerance, easy cleaning/maintenance, and a long design lifespan (up to 10 years).
Enhanced Overall Benefits:
- Extends Squeegee Lifespan: Gentle yet thorough cleaning reduces blade wear and corrosion, protecting edge integrity.
- Ensures Printing Quality: Near-zero residue cleaning drastically reduces risks of stencil clogging and printing defects (e.g., skipping, uneven thickness) caused by contaminated squeegees, improving product first-pass yield.
- Boosts Efficiency: Cleaning time reduced to 1/4 of manual cleaning, accelerating squeegee turnover and supporting efficient, continuous production line operation.
Frequently Asked Questions (FAQ)
Q: What are the main advantages of the CN-600SM compared to manual cleaning or solvent soaking?
A: Advantages are primarily in four areas:
- Better Results: >99% cleanliness, eliminating printing defects caused by residue.
- Lower Cost: Saves labor, drastically reduces solder paste waste, cleaning fluid is recyclable. Cost per piece as low as ~¥0.04.
- Safer & More Eco-Friendly: Avoids toxic solvent exposure; filtration reduces pollution.
- Higher Efficiency: Cleans and dries blades in minutes, 4x faster than manual methods.
Q: Will the cleaning process damage my metal squeegee (especially the edges)?
A: No damage will occur. The CN-600SM uses ultrasonic cleaning, a physical “cavitation” process, combined with dedicated eco-cleaning fluid. This process is gentle, non-contact, and will not cause wear or corrosion to the metal substrate (including the precise edges). On the contrary, thorough cleaning reduces chemical corrosion from residues, helping to extend squeegee blade lifespan.
Q: Does the machine require special cleaning fluid? Is the running cost high?
A: The machine is designed to use dedicated eco-friendly, water-based alkaline metal cleaning fluid. This fluid is highly efficient, biodegradable, and gentle on workpieces. Consumption is very low (1 kg can be cycled for 20-50 hours), keeping costs manageable. Combined with the efficient solder paste recovery filtration system and labor savings, the overall operational cost is very low, resulting in a short return on investment period.
Q: What size squeegee blades can the CN-600SM clean? How many can it clean at once?
A: The CN-600SM can clean squeegee blades up to 600mm long, 60mm high, and 30mm wide, covering the vast majority of squeegee specifications on SMT lines. The machine typically features an optimized rotating fixture allowing simultaneous cleaning of multiple blades per cycle (exact quantity depends on blade size and fixture design). Its high efficiency and batch processing capability significantly boost squeegee turnaround time on the production line.
Q: Is the machine maintenance complicated?
A: Maintenance is simple and convenient. Main tasks include:
- Periodically cleaning solder paste residue and impurities from the filtration system (frequency depends on usage).
- Topping up or replacing cleaning fluid as needed.
- Wiping down the external machine and tank after use (stainless steel is easy to clean).
- The machine is designed for easy maintenance, with key components readily accessible.
