1. Input Devices Group Assignment

1.Establish PCB fabrication specifications suitable for lab conditions a. Tool selection (V-bit, etc.) b. Platform calibration (zero point) c. Parameter documentation: cutting depth (recommended 0.1mm – copper thickness), feed rate (recommended 15mm/s – to reduce the risk of tool breakage) d. Safety and environmental requirements: fume/dust control, safety goggles, etc. 2.Submit a designed board to a PCB manufacturer for fabrication a. Gerber files (including drilling layer), etc. b. Alternative methods (e.g., copper etching) may be used.
