The HMH-830 PCBA Coating Machine is a high-precision PCBA Coating System engineered for selective conformal coating in SMT production. As a flagship in the PCBA Coating line, it implements X/Y/Z three-axis motion to precisely spray protective coatings, avoiding non-coated areas such as connectors or components that must remain exposed.
This Conformal Coating machine supports multiple spray modes, including spot coating, linear spraying, and curved spraying, enabling complex, high-density circuit board coverage. The system accuracy is ±0.02 mm in both X and Y axes, and the position accuracy is highly stable. The device can also evenly coat board edges to eliminate shadow effects.
Equipped with two coating valves for automatic switching, the HMH-830 offers high flexibility for dense circuit board patterns. Its intelligent automatic width adjustment, combined with high-speed control and reliable transmission systems, streamlines setup and minimizes manual intervention. The software supports both automatic programming and manual track input modes for flexible customization.
Key specs include PCB transfer height of 920 ± 20 mm, transport speed up to 5,000 mm/min, PCB width handling from 50 to 450 mm, maximum board size 450 × 450 mm, and component height up to ±100 mm. The machine’s dimensions are approximately 1060 × 1200 × 1700 mm with a weight of 650 kg. Power is AC 220V 50 Hz, and the gas source requirement is 4–6 kgf/cm².
Whether used in EMS factories, consumer electronics, automotive electronics, or IoT PCB assembly lines, the HMH-830 PCBA Coating Machine offers stable, precise, and programmable coating performance. As a selective coating system, it ensures your PCBA products receive reliable, uniform protection, enhancing durability and reducing defects in SMT operations.
