To add to Hans' question what is an allowable amount of voids in a BGA
joint. Do IPC standards exist on this?

Hi technetter,
I would like to have some feedback on how a "not approved" BGA solder joint look
like" (except
for an open or bridge). I am referring to eutectic collapsable solder joints.
Can you have "too fat" or "too thin" joints?
