This is just a couple tips and tricks I’ve figured out on how to use fiducials. Specifically, its for our MDC 7722FV pick and place but theres a good chance that whatever p&p you’re designing PCBs for, its gonna be the same.
What are they?
Fiducials are little target registration marks that are printed on PCBs, they are placed on the top copper layer (and bottom if you’re doing 2-layers) and allow the vision system of the pick and place to recognize where the PCB is at. They are not placed on the mask or silk because they are not as precisely aligned to the parts as the copper itself.
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.
