DIC did not report about the root cause of pin hole.
4) Dust defect rate is reducing after PAINT increased line cleaning frequency from every 2 weeks to once a week, but should show defect rate in PPM unit as well. For thin coating problem, improvement action have not been mentioned.
5) About ERL8020B (water immersion claim), AS1 improved by spreading silicone with constant amount especially joint portion and after DDS conducted water spraying test & soaking test(散水・浸水試験), it was OK. However AS1 didn’t make standard about silicone application method, therefore DDS will cooperate with AS1 about this and conduct test again.
