Can you? Yes. Will it work every time... Maybe not!
There are two reasons for this.
- Temperature profile and timing.
Reflow is done using two temperatures, a pre-soak temperature and a reflow temperature as shown below.
As such, you REALLY need to use two ovens to do this right, quickly switching it from one to the other after the pre-soak time.
Commercial reflow is usually done in a nitrogen gas so that oxidation will not occur in the solder and joints during the molten phase. That's rather hard to do in your domestic environment.
Not all components can withstand the same heat. Some parts are MUCH more sensitive to being "cooked" for too long, especially plastic parts like connectors and the like. If you are doing this at home it is prudent to identify those and manually add them after.
Other than the obvious... "Don't burn yourself..." it is not a healthy idea to solder using the same oven you plan on baking that apple pie in later in the day. Lead and other noxious chemical fumes will permeate the oven.
Also, if you are married, severe tissue damage can occur in the rectal area from the insertion of your spouses footwear when she, or he, finds out what you did.
