I see..

still the method with the oven seems quite fast to me..

they just apply a line of solder paste across all the pins and
it sucks itself where it belongs.

I once did a smd board with that oven method, it used no ics, only 1206 and
0804.
you have to apply a small drop of solder paste on each pad seperately here,
i think it was still much faster than soldering with a iron.

If you have a board with, say 5, 100 pin ics it may save quite some time.

sure, the solder paste is relatively expensive.
that keeps me from using the method.

but i really think it is very convenient if you need it often.
