I regularly work on 64 and 100 TQFP chips and I trust hand soldering much more than any solder paste as I know my joints are perfect and short free. If needed I can post a video of how to do it.

Of course one needs a bit of practice, but the TQFP is an extreme case, most SMT parts on the inverter are soics?
The current board has no tqfp parts. There are 6 SOIC16 parts that are pretty easy to solder. I made sure to have the pad stick out past the legs so it's easier to do by hand. There are also a few 1210 caps and resistors. Everything else
is old fashioned through-hole. I wouldn't mind seeing a tqfp video! I could do a tqfp 44pin without much issue with my current tools, but a tqfp 64pin that's still 10mmx10mm (or was it 14mmx14mm??) is pushing it with the soldering tip I have.
