TIL: LED strips can be made in a continuous process in basically arbitrary length: https://www.youtube.com/watch?v=-xYxB-3j7lk
Before watching that video, I was under the impression that LED strips are made of 1m long segments as that's the maximum size of a PCB panel.
But now that LED strips have become an established product, I guess it made sense to develop bespoke manufacturing processes.
Now I want to know how they make that 10-meter long flex PCB.
