US PCB share fell from 40% to 4%: an interactive atlas traces one board's global supply chain
AnneliesGamble · x · 2026-09-10
An interactive atlas traces a single SparkFun RedBoard back to its copper, resin, and solder mask, mapping representative factories worldwide from the 1980s onward. The backdrop: the US made 40% of the world's PCBs in the early 1980s but only 4% by 2023. A live demo and open-source code are available.
