> You reflow the whole board with a hot air station? I've been using an oven. How big a board can you do that way?
Yep. It's not really by choice, but because I have limited space. That being said, I like being able to watch the process and to correct minor issues like a 'tombstone' passive, so I think I'd prefer a hot plate over an oven.
My SMD boards are small, the largest one by length is 7 cm and the largest one by area is 25 sq cm. You could definitely do larger ones, but you'd probably get significant temperature gradients - bad for manufacturing, probably ok for prototyping and one-offs.
