V. FAQ
Q1: Is the CN-8150NS compatible with stencils/PCBs of different sizes?
✅ Customization Supported:
Standard tank fits 740×740×40mm stencils (e.g., DEK/EKRA/GKG models).
Non-standard customization available for oversized/irregular parts (e.g., long squeegees, special carriers) – provide dimensional drawings for evaluation.
Q2: What are the advantages of aqueous cleaning vs. traditional solvent cleaning?
✅ Three Key Benefits:
Eco-Compliance: VOC-free, meets EU RoHS/REACH and China’s environmental regulations;
Cost Savings: Chemical consumption as low as 1/5 of solvent systems (from 30ml/cycle), zero waste disposal fees;
Enhanced Safety: Non-flammable, non-toxic to operators.
Q3: How does the machine protect stencil tension and micro-apertures?
✅ Dual Safeguard Technology:
Dynamic Balanced Spray: Laterally moving nozzles apply uniform pressure, preventing localized stress;
Smart Pressure Control: Adjustable 0.3~1.2MPa (default 0.7MPa) for delicate FPCs to thick stencils.
Q4: What’s the cycle time? Does drying eliminate water marks?
✅ High-Efficiency Workflow:
Standard Cycle: Wash (3min) → Rinse (2min) → Dry (3min) ≈ 8 min/batch;
Air-Knife + Hot-Air Drying: 80°C airflow ensures zero residue (≤50ppm moisture verified).
