Exactly, you need a toaster oven (pref an IR one) with an accurate temp control that will run a temperature profile that matches the solder used on the board ... in particular it needs to bring the temp of the board to just below the solder melting point and soak the board so it's all at that temp, then quickly spike the temp over the melting point so it all melts at once, otherwise you put silly stress on everything as some stuff melts and some doesn't and you risk tombstoning and other evils So don't just stick stuff in your oven
