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

| Is there process by which one can do a double sided reflow (SMT on both sides) in one pass through the oven? | Probably not. I have heard people talk of it but never see it done and I wouldn't recommend it. Good luck

1) run the BGA side first. set the bottom temp lower (if your reflow oven have top and bottom temp setting) for connector side while doing your 2nd reflow. 2) run the BGA side first with your normal leadfree paste, and run the connector side with low

There is a formula that determines whether a component will fall off during a 2nd reflow. It takes into account the grams (weight) of the component and the total surface area of the solder joints. I don't know this off the top of my head, but it's

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
