joe, how did you get on with an IR oven?
The first few attempts clog up everything. Temperature settings too low or too much solder paste everywhere. The solder paste solvents can evaporate in storage, so mix it with some liquid solder flux to make it flow (and don't breath the solder flux fumes coming out of the oven - take the time to fit proper venting before starting up the oven).
Allow yourself the luxury of destroying 5 boards with cheap chips and components to practice.
After that its regular as clockwork. (Plenty videos on youtube.)
