Running the BGA first is OK. We run double sided BGA baords all the time without problem.

Samir's correct. We've talked about this previously. Search the fine SMTnet Archives for those discussions, like http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=23236

Hi, I believe ,do the BGA side first and then use glue from dispensor for the connector side. THIS CONDITION CAN BE FOLLOWED IF & ONLY IF UR CONNECTORS DO NOT BURN OR LOOSE THEIR PHYSICAL STATES. OR SIMPLY REDESIGN THE

We are using lead paste on both sides, the only reason we need to change the profile is because the BGA is lead free. I decided to run the BGA side first, then the connector side. This way I am not running both sides through on a hotter profile.

Are you using lead free paste also? Are all the other parts on side 1 ROHOS ? etc.. can they handle your leadfree profile. Those need answered 1st. But to answer your question. Yes you can run the BGA side 1st ( hopefully with leadfree paste and ho

I have this board that we are currently having problems with. When we run the BGA side with the hotter temp. the connectors on the other side lift off their pads. The BGA is lead free, that is why we have to use the hotter profile. Would it be

It sounds like something is a little off here. ROHS compatible and ROHS capable parts are going to be ok with a leaded solder paste and processing unless you are building high reliability product.( some are going to argue that even high rel products
