Introduction

In today’s fast-paced renewable energy sector, global companies need suppliers who can deliver not just volume, but also unmatched reliability and speed. Recently, Ring PCB partnered with a well-known energy enterprise in the United Kingdom to fulfill an ambitious project: 100,000 high power supply PCB assemblies for their advanced energy equipment. What made this collaboration remarkable was the client’s demand—the entire order had to be completed and delivered within two months, with an exceptionally low defect rate.

The Client’s Challenge

The client came to us with a clear but challenging request:

• Strict quality requirements – The assemblies needed to meet rigorous international standards with the lowest possible defect rate, as even minor flaws could disrupt high-performance energy systems.

• High-volume production – A massive order of 100,000 units had to be produced.

• Tight timeline – The boards had to be manufactured, tested, shipped, and received by the client within just two months.

• Long-term reliability – Since the assemblies would be integrated into high-power energy equipment, the boards needed excellent thermal resistance, durability, and stability under continuous heavy loads.

It was a project that tested both speed and precision—qualities not every PCB manufacturer can balance at scale.

Our Tailored Approach

At Ring PCB, we embraced the challenge with a systematic and innovative approach:

1. Rapid Prototyping – Within three days, our engineering team developed working prototypes of the high power supply PCB assembly. These were quickly tested and approved by the client, ensuring no time was lost.

2. Process Optimization for Zero-Defect Goals – To meet the client’s low-defect expectations, we enhanced our SMT (Surface Mount Technology) processes, implemented additional inspection points, and applied Six Sigma quality control methods.

3. Automated High-Volume Production – Leveraging our two modern factories in Shenzhen and Zhuhai, covering over 5,000 square meters, we set up multiple production lines running in parallel. This ensured that 100,000 assemblies were manufactured within the two-month timeline.

4. Comprehensive Quality Testing – Every board underwent AOI (Automated Optical Inspection), functional testing under high-voltage conditions, and burn-in tests for reliability. Our quality team worked round-the-clock to maintain consistency and achieve the client’s required near-zero defect rate.

5. Fast Logistics and Delivery – To meet the “two-month delivery and receipt” deadline, we coordinated with international logistics partners to ensure smooth customs clearance and on-time arrival of all goods in the UK.

Results and Success

The outcome of the project exceeded expectations:

• 100,000 units delivered and received within two months.

• Defect rate kept to the absolute minimum, meeting the client’s strictest quality requirements.

• Enhanced performance – The boards operated flawlessly in energy equipment, maintaining efficiency and stability under heavy loads.

• Strengthened trust – The client expressed strong satisfaction and committed to future collaboration with Ring PCB.

Contribution to Renewable Energy

This case is more than just a successful delivery—it highlights how high power supply PCB assembly contributes to advancing clean energy technologies worldwide. By combining speed, precision, and large-scale capability, Ring PCB supports the global mission of building a sustainable future.
