Hi there, We are buying PBGA substrates in strips and allow to have not more than 1 X-OUT per strip or 10% X-out per lot whichever is lesser. We are facing a problem now - the substrates which is X-OUT will still go thru the processes such as molding etc (no die and bonding only). These processes and materials cost work out to quite a substantial amount. How do you take care of that ? Do you force vendors to pay for the additional processes/material costs ? Do you get them to charge you lesser for the substrates if there is certain % of X-out ? Do you have any special formula to calculate ? Would appreciate very much if you can share with me your valuable experience.
