Electronics Production


Assignment Requirements:

  • Group Assignment:
  • Individual Assignment:
  • Learning Outcomes:

  • Describing the process of milling, stuffing, de-bugging and programming
  • Demonstrating correct workflows and identify areas for improvement if required

  • Introduction:

    For the group assignment, we fabricated the resolution test (traces & outline) on 3 CNC milling machines. First on Roland Modela MDX-20, Second on a chinese CNC milling machine and third on MonoFab SRM-20. Each macine has its resolution results.

    For the individual assignment I decided to make Ali's FabOptimus ISP, I chose the Design Files (R_pullup=1K+0.5K).


    Steps in General:


    Steps in Details:

    Step(1): Fabricating the resoultion test on a Chinese CNC milling machine


    Step(2): Fabricating Ali's FabOptimus ISP on MonoFab SRM-20

    Step(3): Stuffing and soldering the PCB

    Step(4): Programming and testing


    Finally, I have:

    √ Characterized the design rules for our PCB production process: documented feeds, speeds, plunge rate, depth of cut (traces and outline) and tooling.

    √ Made an in-circuit programmer by milling and stuffing the PCB and finally tested it.


    Useful Resources & Aknowledge:

  • Saeed and Mrehan did a great documentation for this week assignment which helped me alot.
  • Thanks to Saeed who helped me program the board using the ATMEL AVR USBasp programmer.
  • Thanks to AALTO FABLAB channel on youtube for making videos for each week assignment.
