Surface mount is predominately done in relow ovens. There are not a lot of throgh hole components that are designed for the reflow process. Also appling the solder pate is problematic. There are through hole connectors that are designed for reflow ovens. The paste stencils have larger opening for the through hole parts so that enough paste is applied. Also the hole size for the through hole parts becomes more critical. I have done it on one of my boards where I was using a DIP8 through hole socket. Works OK.
The KISS machines are designed for through hole parts only. I had a chance to purchase a benchtop vapour phase solding machine but wasn't quick enough. It's a very simple process. The machines use a liquid (expensive) that boils at 235C. The process is to heat the liquid to the boiling temp is a container until the vapour fills the container. There is a cooling coil at the top of the container that condenses the vapour if it rises too high as you don't want it to escape. The PCB is then lowered into the vapour. The PCB is then heated to the vapour temperature. The advantage of this system is that unlike infared reflow, larger components don't end up as a heat sink causing uneaven temperatures across boards components. I know guys who have made vapour reflow maching with a 5 gallon drum, PID heater along with a cooling coil wrapped around the top of the drum. I've never tried it though.

But, he didn't use it for the whole board, apparently only for the thru hole parts. The SMT stuff I'd have to assume were done in a reflow oven? He didn't say, but it makes sense. Whole board at once seems like it makes perfect sense as long as it doesn't contribute to the infant mortality rate. > It is a really good example of a startup company doing things right.
