K Kittiporn,
I am preparing eCAR justification package for Upgrade B4L3 clean room project and this project will justify with the reduction in production interruption at B4L3. Formerly, K Kiat will advise us on this ROI calculation. However, since K Kiat left WD, then, I am not sure if you can advise or direct me to the right person who can advise on the impact in $ USD per unit from this B4L3 production interruption. For volume, I will refer 18 M units HDD vol per Qtr for this Qtr. Please let me know if you would like to get any information to support this. Thank you in advance for your help!
