After hand soldering I am getting solder flags on my boards (see attachments). Any one have an idea on how to get rid of these flags or are those acceptable?

Hi Bill, You should try pre-baking any such old devices prior to using on SMT Reflow. Refering to MSL-type3 guidelines could help in your case.

If you can use a IR desoldering station, you could try covering the second BGA with aluminum tape. The tape shouldnt touch the second BGA, it should form a 'roof'over it that reflects the IR waves.

Did you try explaining the problem to your machine manufacturer for direct assistance? Perhaps your machine brochure would indicate a 24hrs helpline service, or any contact no.
