I have populated the board, reflowed using a toaster oven. It worked well, as far as the reflow process went. unfortunately, there are no blinking lights and no communications with the programmer. I am now working on troubleshooting the circut. If I don't get anywhere doing that, I will probably mount the CC8520 chip on a breakout board and test it that way, before attempting another full blown transmitter. I will probably also attempt to remove the chip with the hot air process as well.
