Dear colleagues:
Sorry, but I have to return to the solder balls spec. issue.
I know, that   IPC-S-815B ( 3.6.6) had the criteria for the solder balls  (
less than 0.005", no more than 5 per one sq. inch).

Now, IPC-S-815 was replaced  by J-STD-001.  But , I can not find any solder
balls spec in J -STD.

We are NoClean chemistry users, and will always have tiny  solder balls,
although we are trying to reduce its number.

I need an official document to accept presence of the solder balls up to
the certain level, of course.
Please, help!!
