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

Coating Challenges Before Haipai

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

Solution

HP-730 Selective Coating Machine

H-905I Precision Atomizing Valve – for uniform wide-area spray coating
H-Y01 High-Speed Piezo Jet Valve – for precise coating in tight areas

Trial Results

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

Key Benefits Delivered

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

Customer Feedback

“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.”
