Did this go out twice? I didn't send it twice...

They just had the email servers shut down over
lunch to do some work on them...

Let's see if this one goes out twice.

Huh! What are the odds that two guys with such similar names, working for
the same company, would give such similar answers? It's like Lou Gehrig
getting Lou Gehrig's disease....

                                Hi Cheryl!

                                IPC-600G, section 2.9.3.3 says that if a
soldermask dam (web) was supposed to be
                                there between a BGA and a via, it should be
there, otherwise it's nonconforming.

                                But it doesn't say how big the dam should
be...

                                Kind regards,

                                Do you know if any spec exists defining
minimum soldermask webs
                                (particularly between vias and bga pads)?
                                Any inspection criteria?
                                Your help is appreciated.

                                Sincerely,
