- Confirm that copper tape has better conductivity than aluminum sheet when attaching microcontroller pins through `H-shape` cut
- Copper tape is harder to be scratched, which provides less risk of disconnection during assessmbly.

+ - A package enable drawing through scripts on SVG/DXF file
+ - A script that pulls out pins' coordinate on paper chassis
+ - Or a image process package (OpenCV) that reads pins' coordinate on paper chassis
