Electronics Production

    • Weeks projects Home


    • Group Assignment:
      • Characterize the design rules for your PCB production process
    • Individual Assignment
      • Make an in-circuit programmer by milling and stuffing the PCB,
        test it, then optionally try other PCB processes
    • Link to the group assignment page
    • Document how I made (mill, stuff, solder) the board
    • Document that my board is functional
    • Explain any problems and how I fixed them
    • Include a ‘hero shot’ of my board

      Group Assignment

     

    Chaina Machine

    The group assignment was to characterize the deisgn rules for our machine. Our setup was:

      Chaina machine

      1/32'' endmill

      1/64'' endmill

      6"x8" Single-sided FR1

      Sketch tape

      Double-sided tape

      Vacuum cleaner

      Traces and Interior of the test files

    We started by installing the sketch tape onto the machine bed and the copper sheet.

    This would allow us put double-face tape without suffering from being sticky to the bed nor the PCB.

    So WE Opend fabmodules.org and Upload the tests and output as GCode and then modify the Speed and Press calculate & save the GCode

    then Put the Tool in the Machine and Fabricate the Test

    We found out that the thinnest trace could be milled is 0.001'' (0.0254 mm) and the smallest clearance between tracess could of course as small as the endmill diamater (0.4mm).

    Roland SRM-20

    Place the Copper Sheet in the Ped of Roland SRM-20

    Open the VPAnel and Choose the GCode File of the Test

    The Final Result

      The PCB

     

    For the PCB fabrication I decided to use ISP(AVR) and ATTINY44 ALI's PCB

    So I opend FAB MODULES and Modify the Image to Send It to Modela MDX-20

    After fabricating the PCB the result was amazing

    Note: To make the PCB clear Make the Offset -1

    Begin to Solder the PCB

    And I made another one to Practice More on soldering

    After We Solderd the PCB Now Move To the Best Part, Uploading the Firmware on the Programmer

    And I recommend To download AVRDUDESS To upload the firmware.

    So now I'm Check on the PCB if it's Reading or not

    And It's Detect our chip

    And Now Let's upload the Firmware
