SMMA Transparency Management
Fenómeno do problema
SMMA transparency 89-92%, but processing defects affect optical performance.
Análise das causas
SMMA light transmittance 89.2-92% close to PMMA; but affected by bubbles, impurities and stress marks; surface quality; optical uniformity; testing standards.
Solução
①Defect-free process guarantee; ②surface quality optimization; ③stress management; ④optical testing; ⑤unified standards.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
SMMA transparency is the core value; defect prevention is the guarantee; testing keeps optical quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
