High-precision laser welding for next-generation data highways

White paper on green lasers, AI-powered quality control, and automated copper welding for high-speed connectors in data centres.

High-speed connections of up to 200 Gbit/s form the backbone of modern data centres – and place the highest demands on every single copper connection. This white paper shows how you can use green wavelengths and AI-based image processing to achieve stable, reproducible welding processes for miniature connectors. Learn how TRUMPF laser technology makes it possible to transform processes into highly automated, production-ready manufacturing with first-class quality and repeatability.

Laser welding of critical components for data centres

Cost pressures and a shortage of skilled workers , coupled with growing demand and increasing quality requirements, are forcing manufacturers of high-speed connectors to rethink their joining processes. Using specific applications as examples, the white paper demonstrates how copper conductors and contacts can be welded in milliseconds with process reliability using a green laser and AI-supported image processing – with >99% good parts, stable signal quality, and a clear vision of fully automated production lines.
