SMMA Haze Control
Problem Phenomenon
SMMA haze <2% requirement, but improper processing raises it.
Cause Analysis
SMMA haze usually <2%; but impurities, bubbles, crystallization and surface defects increase haze; optical applications are strict; testing and screening.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Pure raw material; ②defect-free process; ③surface quality; ④haze testing; ⑤optical screening.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
SMMA haze control is the key to optical quality; whole-process prevention; screening keeps delivery.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
