A three-axis selective conformal coating machine applies protective coatings with pinpoint accuracy on PCBs using programmable X-Y-Z motion control. Ideal for complex layouts, it targets specific components while avoiding connectors, sensors, or heat sinks. The system employs non-contact dispensing (spray, jet, or needle valves) to deposit acrylic, silicone, or urethane coatings in controlled thicknesses. Integrated vision systems or CAD-guided paths ensure error-free application, even on high-density boards. Adjustable parameters accommodate varying viscosities and curing requirements. By minimizing overspray and material waste, it enhances efficiency in aerospace, automotive, and medical electronics, where precision and compliance with IPX standards are critical.
This machine delivers micrometer-level accuracy for intricate PCB layouts, dynamically adjusting coating paths in real-time via programmable three-axis motion. It excels in masking fine-pitch components, connectors, and micro-vias while ensuring uniform material distribution across uneven surfaces. Equipped with adaptive flow control, it handles varying board thicknesses and high-density assemblies without clogging. Real-time diagnostics monitor spray consistency, preventing under/over-coating defects. Compatible with nano-coatings for ultra-thin layers, it meets MIL-I-46058C specifications for military and telecom hardware. By combining speed with exacting repeatability, the system reduces rework and ensures compliance in mission-critical applications where design complexity demands flawless environmental protection.
This machine offers unmatched versatility, adapting to diverse PCB geometries and production volumes with rapid programming and tool-free changeovers. Its three-axis precision eliminates masking needs, reducing labor and material costs while coating tight spaces like under components or between pins. Intelligent path optimization minimizes cycle times and ensures 100% coverage on high-reliability boards. Compatible with eco-friendly, low-VOC coatings, it aligns with sustainability goals. Scalable for R&D prototyping or full-scale production, the system future-proofs manufacturing lines, delivering defect-free protection for automotive sensors, IoT devices, and wearable tech where miniaturization and environmental resilience are paramount.
