So you're saying that once you've soldered the device in, you then apply 
more flux, and reflow it.

What sort of hot air pencil are you using?

What flux do you use?

How long does it take to get hot enough to reflow the device so that it 
aligns? I would be nervous about overheatin the ic.

How big (how many pins) are the devices you use this technique with.

Thanks again for the education.
