One thing that always used to give me grief at home was loading fine pitch surface mount IC's.
I recently bought a toaster oven having read several people's experience using these to relow SMD's.
I lashed out and bought the el-expensivo fan forced model, as this was in one forum reported to give more even heat. After some playing around I concluded the oven would actually be really very good.
I found that if I did the following (with my oven):
- Turn on and run on 2 bars until temperature = 100C,
- Turn down to one bar, and run for 60 seconds,
- Turn on two bars and continue until the temperature is 210C,
- Turn all bars off, leave fan on and open the door a crack.
The heat continues to increase to about 220, and the profile is really very close to many manufacturers recommended profiles.
