Hi Everyone, I haven't been reading the list for a few weeks, forgive me if I am putting forth old ideas. I've soldered up boards using an ordinary electric oven and solder paste. Put paste on the pads of the board using as little as possible. Place the parts on the board(small parts first). Set aside. Preheat to 425(fahrenheit) with an upside-down cast iron frying pan inside. After the oven has settled(10 to 15 minutes) place the board on the frying pan, and close the oven. Let bake for 3 minutes. Take the board out and let cool. -Bob http://www.bobblick.com/
