#547 Flying test probes for automated boardview generation

  • Assumptions for creating this machine:

    • (if this is making it any easier) board was scanned beforehands so extra constraints can be added (like extra mounts for PCB, in the middle of it)
    • PCB was stripped out of every component
    • Pads may be slightly oxidized
  • Rail with 2 probes on which they can move freely (possibly being able to measure 0402 distance), then having rotation and X/Y translation of that rail

    • cons: ridiculously slow and complex movements
  • Double (stacked) CoreXY arrangement where each head would attempt to stay within their square. See https://reprap.org/wiki/CoreXY . So if we assume single sided board and that we are figuring out connections of particular pad - One part of the board would be tested with one board and other with 2nd one - ie. at some point probe which stands still on a pad would need to switch.

Some videos showcasing various commercial machines:
