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: 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. 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. 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. 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. 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.

A Client’s Ambition, Our Challenge When a U.S. electronics manufacturer approached Ring PCB with an urgent request for 20,000 extra-long 900mm PCB assemblies, we knew this was not a routine order. These boards were critical to the client’s next-generation product line—requiring exceptional reliability, flawless signal performance, and precise assembly at a scale rarely attempted in the industry. This was more than just production. It was about transforming a bold idea into reality. The Unique Challenge of 900mm PCBs Manufacturing standard-sized PCBs is complex in itself. But once a board reaches 900mm in length, the challenges multiply: Warping Control – Extra-long boards are highly prone to bending during lamination and solder reflow. Layer Precision – Even micrometer-scale misalignment across such a length can compromise circuit integrity. Handling & Transport – Boards of this size demand customized fixtures for every stage, from SMT assembly to packaging. High-Speed SMT Assembly – Placing components with absolute accuracy across nearly a meter of board length pushes machinery to its limits. This project required not only advanced equipment, but also creativity, teamwork, and engineering excellence. Our Tailored Solution At Ring PCB, we thrive on solving the “impossible.” For this project, our engineering and production teams developed a specialized workflow to meet the client’s requirements: Custom Tooling & Fixtures to keep each PCB flat and stress-free during every process. Optimized Thermal Profiles that controlled temperature gradients during reflow soldering, reducing warpage risks. Full-Length Automated Optical Inspection (AOI) to ensure that every single solder joint was flawless. Integrated Turnkey Workflow that combined procurement, assembly, testing, and logistics—delivering efficiency and reliability at scale. The result? 20,000 perfectly assembled 900mm PCBs, shipped on schedule, enabling our client to launch their product without delays. The Result: Innovation Delivered For our U.S. partner, this wasn’t just about receiving PCBs. It was about confidence—knowing their bold design could be manufactured at scale, without compromise. For us, it was a demonstration of what Ring PCB does best: turning complex challenges into seamless solutions. Why Ring PCB? With 17 years of experience, 500 skilled employees, and over 5,000㎡ of modern self-owned factories in Shenzhen,China, Ring PCB is more than a supplier! https://www.turnkeypcb-assembly.com/

To repair faulty or damage trace pathways, you simply need to resolder or reball the board with the necessary material. This reconnects the broken circuit and allows electricity to flow freely throughout the board.

PCB is an acronym for printed circuit board. It is a board that has lines and pads that connect various points together. In the picture above, there are traces that electrically connect the various connectors and components to each other. A PCB allows signals and power to be routed between physical devices.

The most basic function of a PCB is to enable a simple action in an electric device. A PCB provides channels and pathways for the electricity and signals to follow. This allows a device to function on the most basic level. Without a PCB, a device might not even turn on.
