We are informed by our engineer leader, who is in charge of one of our factory A4 (QFN production), they want to lock the lead tip tilt upward issue.
Because it may impact to our wire bond or bleeding issue, and compare with other suppliers, they don't need to waive this spec and always follow upward 0 Max.
It seems it is really a serious problem now.
Therefore, we need you to make improvement study, and make another meeting in Q4 2015.
Actually, I have already received the direction from internal, they ask to lock all type QFN FAI from now on, until your improvement feedback.
And it really makes me pain, because we are going to convert more Mech QFN business to MHT as you know.
Therefore, I propose you can study first and let's have another QBR in December. And pls bring your RD engineer come, we need to discuss it very detail.
Main issues :
1. EBO issue
2. Roughness solderability issue
3. QFN Lead tip tilt issue
1. Mech QFN tooling (How much MHT can support in conversion case, we can tie up some condition but need to discuss.)
