I have made some tests with such a toaster oven and found out, that heat distribution over a larger PCB is highly uneven! And this, allthough the oven was rather small and had four quartz heaters! So, to be sure that all solder joints have been entirely smelt, the board will get overheated finally.
A computer control of heating is not needed, if you put a temperature sensor (thermocouple) into the oven and simply switch-on and -off the oven by hand at suited moments. After some test runs you can easily perform the needed temperature profile. After reaching 150°C the oven should be held on same temperature before heating up to 250°C, by the way. This is needed for the activation process. Kai |
