I have had a lot of success soldering SMT chips (80 pin, etc) using toaster oven reflow. The trick is to make sure you have a good solder mask layer on the PCB (I use
https://www.4pcb.com to make my boards and have no trouble). Then you use a reflow designed solder, not wire solder. It comes in a syringe which you can squirt out -- ~10^1 micron sized beads suspended in flux. You place the solder using the syringe manually on each pad, or you can stream it across the pads -- the latter sometimes leads to shorts if you use too much solder.
Once the board is loaded with solder, you place the chip on it, put it in the toaster oven and watch it using a flashlight. After a couple minutes, you'll see the solder suddenly melt -- wait a few more seconds for all the flux to burn away, and then turn the oven off and open the door to let the board cool.
Occasionally (especially before you've had practice) you'll have to manually solder a couple pins that didn't get enough solder or got too much (and shorted). When you've got the hang of it it just works.
I recommend using a dedicated toaster -- don't also use it for food!
Piece of cake! I hope this helps.
