![]() Check your datasheets to make sure your components can handle whatever temperature your solder paste melts at, and for how long. I can't remember the specifics, but I usually give it roughly 90 seconds to come to a "warm-up" temperature, then jack it up to my final baking temperature (I think it spends about a minute or two in that phase). I have successfully reflowed many boards with different ICs and have never had an issue. I have used older toaster ovens, and they work just fine for hobbyist work, but if you're going to pick up a new one then spend the extra $10 or so to get convection. The convection bake mode is important, as it more evenly distributes the temperature in the oven which prevents hot spots from frying components or cold spots from forming cold solder joints.
