| High Precision Solder Paste Dispenser Machine
The SMT Solder Paste Dispensing Machine is designed for high-density PCB production requiring precise micro-volume dispensing. It supports semiconductor packages, board mounting, LED back-end, Mini-LED, PC hard drives, ICs, and BGA assemblies. Combining linear motor drive, laser height measurement, high-speed vision, and automatic compensation, it ensures consistent solder paste and adhesive placement. The system automatically corrects PCB warpage, compensates for chip deviations, and controls dot size, path, and glue volume. Operators benefit from reliable deposition, reduced rework, and improved production efficiency on fine-pitch SMT boards.
| Feature of Solder Paste Dispensing Machine
Transmission Structure System
The machine adopts X/Y linear motor drive with a load-type gantry, maintaining stability during high-speed micro-volume dispensing. Reciprocating accuracy reaches 3σ ±5μm for X/Y/Z axes, while dynamic accuracy reaches 3σ ±3μm. This precise motion ensures consistent dot placement across dense boards, high-density ICs, and Mini-LED modules. Stability is critical for repeatable micro-dot application, avoiding deviations that can compromise underfill and solder paste quality. The gantry design minimizes vibration and ensures high-throughput dispensing without sacrificing positional precision, forming the foundation for reliable high-speed SMT operations.
Function Configuration
The system adapts to real-world PCB variations, automatically correcting needle height based on three-point PCB measurements. It accommodates subtle substrate warpage, ensuring consistent dispensing distance and material volume. Upper and lower dual cameras monitor underfill penetration during flip-chip processes and provide feedback for successive dispensing actions. The platform can be customized for different PCB sizes, material viscosities, and process requirements. This configuration allows operators to maintain stable micro-dot placement for solder paste and adhesive, reduces manual intervention, and improves repeatability across batch and mixed-model production.
Vision Non Stop
Vision non-stop capability keeps inspection and compensation running alongside high-speed dispensing. The system can detect up to 100 chips per second, automatically identifying chip position and height deviations. It adjusts path and glue volume in real time, including compensating overlapping areas to reduce excessive material. This ensures precise micro-dot placement without halting production. For SMT PCB assemblies with tight component spacing, the continuous visual feedback prevents missing dots, minimizes rework, and ensures consistent application quality. This feature integrates inspection and dispensing seamlessly, improving both throughput and accuracy in automated PCB production.
Configuration Options And Applications
Valve selection is flexible: screw valves for high-viscosity adhesives or solder paste, jet valves for more fluid materials. The minimum solder paste dot can reach 110μm, suitable for ICs and BGA assemblies. Applications include semiconductor packages, PCB board mounting, LED back-end, Mini-LED, and PC hard drives. This High Precision Dispensing System can handle multiple material types and sizes while maintaining repeatable accuracy. Engineers can adjust speed, valve, material, and path parameters, making it ideal for factories with varied SMT PCB production needs. It provides a single platform for multiple high-precision dispensing tasks.
