It will probably be late Saturday night or Sunday afternoon, but I will post the profiles, schematics and code (none of it is on this computer). I just used simple thermostatic control (no PWM) and it stayed within 2 degrees C of where I wanted it to be when it could keep up. I only got about 0.5 to 1 degree per second. I may move the lower heating element (quartz tube) up to the top to double my heating power or even buy a second oven for more elements. Even with this slow heating, not even the connectors were damaged.Darrell Harmon wrote:

I did successfully attach the BGA using a $20 toaster oven. I used a MAX6675 thermocouple to SPI converter connected to the parallel port of my laptop along with a relay to switch the power to the oven. I set the oven on broil and got mostly infrared heating. I can post the temperature profiles if anyone is interested.Let me echo ...hello.....hello....hello...
I have had very complex board built with these tools. If the boards anyone else is trying to build dont work it is probably do to the manufacturing process of the boards and not due to the design tools. Hey if you can attach a bga with a toaster more power to you (or the oven got the bread the right collor of brown). using companies that are good at depositing 900 pin bgas has been successfull.

I'd like to see the profile. Now when you outfit your toaster oven with ethernet, then I'll be impressed ;) Still, thats pretty cool. I take it that you're actually regulating temperature not just monitoring it?
