Fab Gurus,

I have seen post separation on my assembled board and also resin smear. I
have few question in that regards.

(1)Can any one provide me the possible causes for the defects?
(2)How much is a variation for this kind of defects within a same date code?
(3)What about the reliability of my assembled boards?

Also being new in fab business, can any one suggest books that talk about
the fab processes and also that talk about possible causes. I am of the
opinion that I should know more about the fab than the fab supplier so that
no one can try to cheat you!!!

I would really appreciate anyone's help.

Regards,
Ken Patel
