Week 8 - Electronic production¶
Assignments | Week 8 | Electronics Production
Group assignment
Characterize the design rules for your in-house PCB production process: document feeds, speeds, plunge rate, depth of cut (traces and outline) and tooling. Document your work to the group work page and reflect on your individual page what you learned
Individual assignment
Make and test the development board that you designed to interact and communicate with an embedded microcontroller
Learning outcomes
Described the process of tool-path generation, milling, stuffing, de-bugging and programming Demonstrate correct workflows and identify areas for improvement if required

Introduction¶
Building on what we learned during the electronic design week (week 6), we will be focusing on producing a development board this week.

CNC PRODUCTION¶
CNC Production consists of
| Step | Action | Result |
|---|---|---|
| 1 | In KICAD go to File and click Plot | A window with the select appears |
| 2 | Select F.Cu and Edge.Cuts and export | In the folder of your kicad project you’ll see some files has been created |
| 3 | Export the drill files | |
| 4 | Transfer these file to the pc connected to the machine |
Now I have the gerber files, I’m facing a question.
How do I choose the right mill for machining the pcb?
I asked Clara, my classmate that already has done her board.
She said: It depends of the minimum clearence between two paths of my design board. And
Fraise cylindrique and fraise conique difference
In FlatCAM
- I opened the files
- Double click on the F.Cu
- Choose the tool’s diameter
- Change parameters from wikisu
- Click on Generate CNCJob object
- Save CNC Code
Double click the Edge.cuts Click on Cutout tool Choose the diameter Generate Freedom Geometry Click, check the parameters and generate cnc object Save cnc code
Turn On the machine Open the control pannel Set X/Y origin Set Z origin (2 checks) Close the cover Take mask and glasses Cut Delete all the output files if it exists Add your cnc project(gravure first)
When I’m on the step of setting X/Y origin, I suddenly realized that my project wasn’t at the right place. so I moved the pcb.
