In late August, a UK-based marine equipment supplier approached Ring PCB with an urgent and highly technical requirement. The client needed 35,000 pieces of custom high-power supply PCBA designed for installation in luxury motor yachts. This was not an ordinary project—marine applications demand durability, efficiency, and absolute reliability in challenging environments. With our 17 years of expertise and modern factories in Shenzhen and Zhuhai, we were fully prepared to deliver a solution that exceeded expectations.

The Client’s Challenge

The customer faced several critical challenges:

1. Harsh Operating Environment – Motor yachts operate in saltwater conditions, where humidity, corrosion, and vibrations can severely impact electronic components. The PCBA had to withstand these stresses without compromising performance.

2. High Power Demand – Unlike small electronics, marine-grade power supplies must deliver stable and continuous current to support complex onboard systems such as navigation, lighting, and communication equipment. Any failure could disrupt yacht operations and pose safety risks.

3. Tight Delivery Timeline – The client’s production schedule required rapid turnaround. The initial request was for 35,000 fully assembled units to be delivered in staggered batches, beginning within a few weeks.

4. Zero Tolerance for Defects – Given the high-value market of motor yachts, even minor PCB assembly defects were unacceptable. The project demanded an extremely low failure rate and flawless quality assurance.

Ring PCB’s Technical Approach

At Ring PCB, we understood that meeting these requirements would require a combination of advanced engineering, careful material selection, and efficient production management.

• Customized Design Support: Our engineering team worked closely with the client to review schematics and optimize layout for thermal management and mechanical stability. High-power components were strategically placed to reduce heat accumulation and minimize electromagnetic interference.

• Marine-Grade Materials: We recommended using corrosion-resistant surface finishes and conformal coatings, ensuring that the assemblies could endure salty and humid marine conditions.

• Automated Assembly Lines: Leveraging our 5,000+ m² modern facilities, we deployed SMT (Surface Mount Technology) and wave soldering processes optimized for large-scale, high-power PCBA production.

• Comprehensive Testing: Each batch underwent In-Circuit Testing (ICT) and Burn-In Testing under simulated marine conditions, guaranteeing reliability and stability before shipment.

Overcoming the Time Constraint

One of the project’s highlights was our ability to meet the client’s strict timeline.

• 3-Day Rapid Prototyping: Within three days of receiving the finalized design, we delivered functional prototypes for client evaluation.

• 7-Day Batch Production: Once the prototypes were approved, we scaled seamlessly into mass production, with the first 10,000 units delivered within just seven days.

• Staggered Delivery: By scheduling phased shipments, we ensured that the client’s assembly line was never delayed, aligning production with their yacht-building schedule.

Achieving Ultra-Low Defect Rate

Our client’s priority was long-term reliability, so defect control was critical.

• Quality Management System: Ring PCB strictly follows IPC-A-610 and ISO9001 standards, maintaining precision across every stage of production.

• Defect Rate Below 0.2%: For this project, our quality monitoring achieved an exceptionally low defect rate—well below the industry average.

• Client Feedback: The UK client praised the outstanding consistency, noting that not a single yacht delivery had been delayed due to PCBA performance issues.

Service Excellence Beyond Manufacturing

Beyond technical execution, the cooperation highlighted our commitment to exceptional customer service.

• Dedicated Project Team: We assigned a specialized project manager to handle daily communications, ensuring transparency at every stage.

• Real-Time Updates: The client received production progress reports and quality data in real-time, giving them confidence in meeting their deadlines.

• After-Sales Support: Our service team provided comprehensive documentation, warranty coverage, and post-delivery technical guidance.

Results and Client Satisfaction

By early September, the client had successfully integrated the first batches of Ring PCB’s custom high-power supply PCBA into their motor yachts.

• Timely Delivery: All 35,000 units were completed and shipped on schedule.

• Unmatched Reliability: With a defect rate below 0.2%, the assemblies exceeded marine industry expectations.

• Strengthened Partnership: Impressed by the speed, quality, and professionalism, the client has since signed a long-term cooperation agreement with Ring PCB, covering future yacht models and additional marine electronics projects.

Conclusion

This case study highlights how choosing the right partner can transform technical challenges into successful outcomes. The UK marine client needed speed, reliability, and premium quality. Ring PCB delivered all three, backed by 17 years of experience, modern facilities, and a culture of service excellence.
