5. Electronics production

Class

Assignment

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

Previous year

Assesment

  • Electronics Production
  • Learning outcomes
  • Described the process of milling, stuffing, de-bugging and programming
  • Demonstrate correct workflows and identify areas for improvement if required

    Important note: As outlined in the Commercial Boards policy, fabbing your own boards is an important part of Fab Academy. The ‘fabbest’ way to do this, is by milling your FR1 boards via Fab Modules or Mods.

Have you?

  • Shown how you made and programmed the board
  • Explained any problems and how you fixed them
  • Included a ‘hero shot’ of your board
