Because modern electronics components are tending more and more towards becoming SMD-only, and because the associated size reduction can also be very useful for space projects, we need a reflow oven.
Status
Oven has been acquired. It is a cheap 1kW Everglades toaster oven. It remains to be seen if it is powerful enough to reflow in a sensible amount of time. First components for the controller have been ordered.
Controller
To be constructed. Will probably consist of a large triac to switch the heating element and a fan on and off in a control loop with a thermocouple. We still need a decent fan to speed up the cooling phase. Needs to be able to withstand rather high temperatures, something from an oven would be ideal.
