There are also problems with some components. If you get samples from
some suppliers of chips, you might get samples taken before the final
burn-in procedure. This means you might

I'm wondering if it wouldn't make sense to also classify

for their footprints. E.g., wave soldering footprints

You can try this one, I have reduced the TQFP64_08 that I use but I have no 44pins body at home to check it.

There are also problems with some components. If you get samples from some
suppliers of chips, you might get samples taken before the final burn-in
procedure. This means you might have moisture in the chips. These chips need
to be "baked" in 125C for 24 hours before reflow soldering.

Have anyone here actually done this? I have searched and a lot of

It's intersting ! I googled "Reflow Soldering Oven toaster" and got many
pages how to do with pictures with out any pay.
I printed those pages and now start to read those pages.

Hiroshi,
I tend to agree with Andy on this.
A reflow oven is an intelligent convection zone oven where you have pre
heating phase, reflow phase and a coling phase. Good reflow ovens
continuously measure the surface temp of the tinned PCB for a quality solder
process. Still, the chips needs
Before
you do this I would go back to the datasheet. You will end up destroying the
device if not the board. My suggestion would be to find a local company in your
area (if one exists) and give one of the assemblers a few bucks to do it for
you. If not there are a few prototype assembly ho
