Recently, Assy encounter problem at DB process due to tie bar/pad tilt situation on 0100QP064C04DM.
PE conducted DOE study to verify allowable gap between nozzle to pad to prevent epoxy abnormal dispensing pattern.
Thus, PE suggest to tighten pad tilt spec from 80um to 40um. Could you help to give your comment regarding this PE requirement?
Please refer below for more details and background. We can set a meeting to further discuss this item.
