Fellow Technetters,

        I am fairly new to the world of BGAs and we have only built limited
quantities of CCAs with BGAs (388s and 352s on 17 layer PWBs) for internal
customers.  I am seeing a first time yield of approximately 96%.

        Is this particularly bad for a low to mid volume environment?  What
kinds of FTY are other folks achieving?

Thanks in advance,
