KL7NA Specific Build Notes
The basic method follows this video. I used the solder stencil to put on the solder paste. Then the surface mount components were placed. Then the board was baked in a reflow oven. This was repeated for the top. Surface tension holds the bottom parts on when you reflow the top. Then the solder bridges were removed with a very fine solder wick and a good soldering iron. Then the through hole parts were soldered in.
