Work an FMEA on a charger defect
Use FMEA to convert a charger defect report into a prioritized control action.
Pilot production shows 4 of 600 bundled USB-C chargers intermittently fail fast-charge negotiation, and the same circuit relates to thermal cutback. FMEA: failure mode -> effect -> occurrence -> detection -> control action The common trap is to treat a low pilot rate as acceptable without checking severity and detection weakness. Failure mode Name the specific failure: fast-charge negotiation intermittently fails, with possible thermal cutback interaction under high load. A precise failure mode prevents the team from dismissing the issue as generic charger weirdness. Effect and risk Effect is not only slower charging. Possible effects include heat, device stress, customer…
