There are even people doing BGAs in toaster ovens.

We used to send our BGAs out to assembly houses, out of pure fear.
Then we tried some in-house. We bought a bunch of inspection and
rework gear, which we've mostly never used. Our yield so far is
100.0%.

What are you using for an oven?

Are you doing 1 or 2, or small batches like 10 or 20?

We have an Essemtec (Swiss) reflow oven, which has pretty good profile
control. Batches are typically in the 5-10 range, but we sometimes do
one or two protos. We have two Essemtec semi-auto p&p machines, so we
really can't load a lot of boards in one day. If we get 50 or so,
we'll often send them out to a board stuffer house.
