PEI Supplier Technical Documents
Problem Phenomenon
The determination of PEI processing parameters relies on supplier technical documents; incomplete document acquisition leads to process errors.
Cause Analysis
Actual PEI production requires fine-tuning parameters according to the technical manuals provided by material suppliers; technical documents from suppliers such as SABIC and ISO standards are professional data sources; document version and completeness; grade differences.
Solution
①Request complete supplier technical manuals; ②confirm parameters according to the grade; ③document version management; ④supplier support for technical issues.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
The authoritative source of PEI process parameters is the supplier manual; version management prevents expiration; technical support channels are smooth.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
