HP-7302 Selective Conformal Coating Machine With Dual Valve Simultaneous Spraying

HP-7302 Selective Conformal Coating Machine
Dual-Valve Simultaneous Spraying with ±0.02mm Repeatability
Advanced PCB Coating Productivity
The HP-7302 Selective Coating Machine offers unprecedented process flexibility with its manually adjustable dual-valve design. The two precision atomizing valves (H-905) can be positioned anywhere from 50mm to 260mm apart, allowing operators to optimize valve spacing for specific board layouts—whether coating two separate narrow boards simultaneously, covering wide areas in a single pass, or positioning valves precisely around complex component geometries.
Precision Coating Performance
Each valve independently delivers the proven H-905 performance: 1mm edge accuracy, low-pressure atomization, and compatibility with all conformal coating types (50-1500 CPS). The servo-driven motion system maintains ±0.02mm repeatability across the entire 450*450mm work area, while the electrically adjustable conveyor (50-450mm) accommodates diverse PCB sizes. For contract manufacturers and high-mix facilities running varied board types, the HP-7302's adjustable dual-valve configuration delivers unmatched versatility.
Key Features & Benefits
  • Dual H-905 precision atomizing valve configuration delivers exceptional spray quality with fine atomization and precise pattern control
  • Manually adjustable valve spacing from 50mm to 260mm provides flexibility to coat two separate areas simultaneously or two boards side-by-side
  • Dramatically increases production throughput without increasing floor space requirements
  • Servo motor + ball screw module drive system across X, Y, and Z axes ensures outstanding performance
  • ±0.02mm repeatability for precise selective coating around sensitive components and connectors
  • High-speed operation with maximum X/Y speeds of 800mm/s and Z-axis speeds of 300mm/s
