Week08. Electronics Production

1. Assignment and Result

About the process, I made new page and made links are below, because the long page makes me confuse.

GROUP ASSIGNMENT THE RESULT
- characterize the design rules for your in-house PCB production process Process -> Kitakagaya: Week8 Electronics Production
1. Board Design (2D data)
2. Create tool Path (MODS)
3. Milling (MDX-40A, using VPanel)
- extra credit: make it with another process
- extra credit: send a PCB out to a board house
INDIVIDUAL ASSIGNMENT THE RESULT
- make and test the development board that you designed
to interact and communicate with an embedded microcontroller		 PROCESS -> ATtiny414 Board with LED and Switch
1. Design board with Kicad.
2. Create tool Path (V Carve Pro)
3. Milling (MDX-40A, using VPanel)
4. Soldering
5. Programming (Arduino IDE, and ChatGPT)
- extra credit: make it with another process -

3. The Video

I put the map on the board. The map is for Kinki region in Japan, and the LED is location of FabLab West-harima, FabLab Kobe, and FabLab Kitakagaya. The each LED blink with each pushbutton switch, as below Video shows.

4. Main Flow of Electronics Production

  1. select chip & parts and check datasheet
  2. Board Design
  3. Create tool Path
  4. Milling
  5. Soldering
  6. Programming

5. My Thought

  • The first time I cut a board in pre-study, it took a long time and try a lot. During pre-study, need to mill so many hours, as the mill is not reached to board. One time, the mill flute is broken, as I made the mistake the wrong origin.
  • I think I was able to cut the substrate well because I have practiced many times before and took on this week's challenge.
  • Creating a board is very time consuming, about design board, and Soldering, and tester and programming.
  • Soldering small electronic components is extremely difficult. Soldering small parts (especially ATtiny414 and FT230) leg by leg was quite difficult. I realized my old eyesight for the first time with this solder. I thought it would have been easier if I had taken FabAcademy when I was younger.
  • During the soldering process, we checked many times to make sure the orientation of electronic components is correct.
  • We learned in advance to use Kicad and to solder, which was good. Otherwise, I would have cried by now.
