A brushless motor can spike to tens of amps in an instant at stall \u2014 if the copper foil can't hold up, the entire board becomes little more than a fuse. This article draws on real production failures to explain why heavy copper PCB manufacturing, redundant shutoff paths, and physical creepage design matter more to EPB safety than any MCU's ASIL certification alone."}
