From the project

A group of RC2014 PCBs I've designed to expand my system

I've used SMT on pretty much all the boards. In my professional life I've done a lot of work with SMT and don't find it that difficult. I'd recommend some solder paste and a hot air setup along with a good soldering iron, a flux pen and various sizes of solder wick. I've converted a toaster oven into a reflow oven for when I'm doing more that one unit builds. This route requires you purchase a solder paste stencil with your PCBs.
