The HP-740 Conformal Coating Machine is an advanced four-axis selective coating system engineered for demanding high-density PCB applications. Featuring a unique rotating U-axis powered by a servo motor with ±180° rotation capability, this system provides unprecedented access to complex board geometries that standard three-axis systems cannot reach.

The innovative four-axis design (X, Y, Z, U) enables precise selective spraying around connectors, tall components, and other sensitive areas. The U-axis rotation allows the coating valve to approach components from optimal angles, ensuring complete coverage while maintaining tight edge definition.

• Ideal for boards with components on multiple planes or recessed areas
• Eliminates shadow effect for superior coating coverage
• Handles complex geometries with precision

The system combines two specialized valves for maximum versatility:

• H-A01 Precision Atomization Valve: Provides fine, uniform spray coating with 0-45° manual tilt adjustment
• H-D01 Impact Needle Dispensing Valve: Designed for spot applications and underfill requirements

This configuration supports various coating patterns including point coating, line spraying, curve spraying, and multi-track spraying.

Advanced servo motor + screw drive module system delivers exceptional performance:

• Repeatability: ±0.02mm
• X.Y Maximum Speed: 800mm/s
• Z Maximum Speed: 300mm/s

Ensures consistent, precise coating application across high-volume production runs.
