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.

• extra credit: send a PCB out to a board house

• 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

• extra credit: make it with another process

Step 04: CAM File Preparation & Manufacturing¶

CAM File Preparation¶

• Export design files as high-resolution images (.svg) distinguishing traces from the board outline.

• I Used mods CE software to generate toolpaths and G-code numerical control files.

Machining / Milling¶

1. Fix the copper plate (FR1) onto the milling machine bed.
2. Set the origin point (X, Y and Z at the copper surface).
3. Mill the internal traces, then cut out and drill the board.

🔩 Assembly & Soldering (SMD Soldering)¶

1. Clean the board after machining.
2. Solder the surface-mount components microcontroller, resistors, capacitors, connectors following the component placement plan (BOM/layout).
