A video of the PICqueno32 prototype build and test process. About 70 minutes of soldering is reduced to 5 minutes.
First the big chips go down. This board has a 64pin TQFP PIC32 and a 28pin SOIC FT232 USB->serial chip. We had to salvage the FT232 from an old Bus Pirate prototype.
Next the small passive components are soldered. A spot of solder goes on one pad of every part. Parts are soldered in place on one side. When all the parts are on the board the remaining sides are soldered at once.
Connectors, headers, and through-hole stuff goes on last.
We’ll try to document all future prototype builds. The first test was rough, but it gave us ideas for next time.
