I use a Black and Decker toaster oven I got off Amazon for $25[0] Works great, super cheap, even heating is important in cooking after all. I set the second dial on "Bake" and the third dial on "Stay on" then use a stop watch and the first dial to control the temperature according to what-ever re-flow profile I'm trying to achieve. You can tell when the oven reaches temperature by listening to the relay click noise it makes.
You can buy an add-on controller for this kind of oven called the reflowster but I don't personally think it is worth the money at $140. The stopwatch method hasn't failed me yet.

- msandford 10y agoI feel like a convection oven might be the next level of reliability in this space. You should at least get very even heating since the airflow is fast enough to be turbulent.
- Animats 10y agoReflow is supposed to be done with convection heating, not radiant heating. The industrial reflow machines are all pure convection. Usually with rather low air speeds, to keep from knocking the parts off the board during soldering. There are good options starting around $1500. Unclear why there's such a huge price jump from the IR rod ovens at $200 and the convection ovens around $1500.
- pmorici 10y agoThey make convection toaster ovens that are about twice the price of basic toaster ovens. The huge price difference on ovens branded for reflow work is almost certainly because of the lower volume of that market.
