Mike, If your wave solder machine doesn't have enough preheat capacity you can put the board in an oven and warm it part way before you put it into the wave solder machine. This works best with a spray fluxer, as a warm board will collapse the foam

With loaded boards, warpage can be removed by placing the assembly in a wave solder conveyor pallet as you would if you were going to wave solder the assembly. Place board and fixture in a Blue M forced air oven at 90 C for 30 minutes. Let cool to r
