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.
