The SMT dual-squeegee closed-loop fully automatic solder paste printer has an independent pressure control function.

OK-SP460-D Dual Scraper Closed-Loop Pressure Fully Automatic Solder Paste Printer

The OK-SP460-D is engineered for precision paste deposition control through dual independent closed-loop scraper pressure regulation. Unlike single-pressure systems, each squeegee (front and rear) is independently programmable for pressure, speed, and stroke — enabling asymmetric profiles that optimize paste rolling behavior for specific paste rheologies and aperture geometries.

Key Features

• Independent Front and Rear Control: Set different pressure and speed for forward and return strokes — higher pressure for initial fill, lower for cleanup stroke to minimize paste bleeding
• Closed-Loop Pressure Feedback: Load cell sensors measure actual applied force 100 times per second with real-time compensation for blade wear and paste viscosity changes
• Programmable Pressure Profiles: Define multi-zone pressure maps across the scraper travel for PCBs with mixed component densities
• Quick-Change Blade System: Tool-free blade change with auto-zero calibration — switch between metal and polyurethane blades in under 60 seconds
• Paste Consumption Tracking: Optional paste weight estimation based on print count and aperture volume for proactive paste replenishment planning

Applications

Optimized for fine-pitch printing (01005/0201) and heterogeneous assembly where consistent paste volume across varied aperture sizes directly impacts first-pass yield. Recommended for smartphone, wearables, and advanced BGA packaging.
