Over the years, I’ve soldered a fair number of boards. I’ve also seen how professional factories produce their boards. This is my technique for doing it myself, and I hope it works as well for you as it does for me. 🙂 Note: the files needed to make the fixture, custom pcb setup, and stencil are on Github – Stencil8. This whole project is OSHW.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
