Optimizing PCB Gold Plating Processes for International Export Quality
Post-Processing Best Practices for Gold-Plated PCBs
After gold plating PCB manufacturing, immediate cleaning with hot water ensures water-free printing and meets international appearance quality standards. For export-oriented PCB production, avoid acidic storage environments to prevent gold surface discoloration. Critical steps include:
- Prompt removal of pad paper
- Thorough inspection for upstream process defects
- Implementation of quality control measures for PCB export
Solder Mask Optimization for Global Markets
Selecting the right PCB solder mask ink for high-temperature applications significantly impacts final product quality. Our testing revealed:
“TARUM TT-9G ink demonstrated zero discoloration in gold plating PCB assembly, while competing products showed visible whitening under identical conditions.”
Key process adjustments for international quality compliance:
- Precise text baking board timing
- Optimized temperature parameters
- Specialized ink selection for high-reliability PCB manufacturing
