FMEA Cheat Deck for Semiconductor Changes
Recall and apply FMEA prompts during semiconductor process, test, or supplier changes.
What is a failure mode? The specific way a function, process step, product, or control can fail. Write 'contact resistance drifts during long lots,' not 'probe card issue.' Failure mode versus failure effect Teams weaken FMEA when they mix these two columns. We do not have time for a full FMEA before this material change. Schedule is real, but the change touches reliability and customer qualification. Your line Then let's run a 20-minute top-function FMEA: highest severity modes, current detection, and release-blocking controls only. Skipping failure-mode thinking because the full template feels too heavy. It preserves the prevention mechanism while…
