I have made the measurement report of carrier tape. Please see result in attached.
Carrier tape’s dimension result
All criteria are accept. So the carrier tape is no problem and no related with this complaint.
SEM result
Although EDX result showed C ( carbon element ) of both particle that it’s difficult to judge what is the particle. The structure of both particles are the same.
What do you think about this ? and I think that we should have more simulations by focus at pack machine operation and m/c set up.
