Hi,


Update from our quality team,


Below are the existing criteria.

While some of these units may fail the criteria, specifically the scratches, we have not had any history of validated failures associated with surface scratches such as what is seen on these images.

Substrate scratches:

  • Reject scratch greater than 80 mils (~2mm) in any direction.

Solder ball criteria:

  • Visible damage at 1x magnification (naked eye or unaided human vision inspection) that leads to out of spec ball height.
  • Reject if any foreign material is found on solder balls with length greater than half the ball diameter.
  • Reject for any visible misalignment (against the pad) at 1x magnification (naked eye or unaided human vision inspection).

Regards,

Aiman

Hello,
Thank you very much for the quick and thorough response.
Just to confirm — would you say that the photos with the defects I sent you look acceptable in the end?
Thank you!
