PEI Quality Data Analysis
Problem Phenomenon
PEI production quality data is scattered and unanalyzed; repeated problems occur; improvement lacks direction.
Cause Analysis
PEI process data, inspection data, and customer feedback are scattered; systematic analysis is lacking; problem patterns are not identified; improvement is blind.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Centralized management of quality data; ②application of statistical analysis methods; ③problem pattern identification; ④closed-loop verification of improvement measures.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PEI quality management needs to be data-driven; analysis reveals patterns; closed-loop verification is effective.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
