Application: Selective conformal coating for PCB assemblies used in smart home appliances
The boards featured densely populated components, connectors, and test points requiring selective coating to prevent moisture and dust ingress while maintaining electrical insulation performance.
Machine Configuration: HP-730 + H-905I atomizing valve + H-Y01 piezo jet valve
| Challenge | Impact |
|---|---|
| Manual masking process | Labor-intensive, inconsistent quality, high rework rate |
| Uneven coating thickness | Led to insulation failures in humid environments |
| Shadowing around components | Incomplete protection on high-density boards |
| Long changeover time | Delayed production for different appliance models |
| Coating waste | High material consumption due to overspray and masking errors |
H-905I Precision Atomizing Valve – for uniform wide-area spray coating
H-Y01 High-Speed Piezo Jet Valve – for precise coating in tight areas
| Parameter | Before | After Haipai Solution |
|---|---|---|
| Coating consistency | Poor (±15% variation) | Excellent (±3% variation) |
| Cycle time per board | 45 seconds | 18 seconds |
| Masking time | 10 minutes per batch | Eliminated |
| First‑pass yield | 82% | 98.5% |
| Coating waste | High (overspray + rework) | Minimal (precision application) |
| Model changeover | 30 minutes | 8 minutes |
Selective coating without masking – Valves automatically avoid connectors, test points and edge connectors
Improved product reliability – Consistent coating thickness ensures long‑term PCB protection
Significant labor savings – Automated process reduces operator intervention
Faster production – Increased throughput without compromising quality
Reduced material waste – Precision application minimizes coating consumption and rework
Quick changeover – Supports varied product models in the same production line
“The HP-730 with the H-905I and H-Y01 valve combination eliminated masking and rework. It’s easy to program, fast to switch between models, and the coating quality is far superior to our previous manual process.”
