Engineers who have taken a PCB from prototype to production: What was the most unexpected issue you ran into?
I'm curious to hear real-world experiences from engineers who have taken a board beyond the prototype stage and into production.
Was it a manufacturing issue, component availability, testing problem, EMI/EMC failure, thermal issue, assembly defect, supply-chain problem, or something completely unexpected?
Looking back, what was the biggest lesson you learned from the transition between "it works on my bench" and "we can build hundreds or thousands of these reliably"?
