I have a question that someone has to have an answer to.

Why is it that the 0 x out yields for a multipack (say 8 x 10) are always
less than a similar sized 1 up (8 x 10)board? Assuming the same technology
level, no gold, and so on.

It seems that multipacks usually see an 80-85% 0 xout yield vs a mother
board with a 95% yield.

If defects are random, how can this be?
