# Goal

- Create a production-ready PCB project named “Sterilizer_Control_1L” with a single-layer (Top only) configuration. The board must have a 90×65 mm rectangular outline with a 1.0 mm copper‑to‑edge clearance, four Ø3.2 mm M3 mounting holes placed 5 mm from each board corner, and three net classes with specified width and clearance settings.

# Implementation plan

1. Project Setup

1. Create a new project named “Sterilizer_Control_1L" and configure it as a single‑layer PCB (Top layer only).

2. Board Outline and Clearance

1. Resize the board outline to a 90×65 mm rectangle.

2. Set the copper‑to‑edge clearance to 1.0 mm.

3. Mounting Holes

1. Place four M3 mounting holes with a drill size of Ø3.2 mm.

2. Position the holes 5 mm from each board corner. Use coordinates (5,5), (85,5), (5,60), and (85,60) mm relative to the board outline.

4. Net Classes Setup

1. Create a net class named "Power_24V" with a track width of 60 mil and clearance of 16 mil.

2. Create a net class named "Power_5V" with a track width of 40 mil and clearance of 10 mil.

3. Create a net class named "Signals" with a track width of 8 mil and clearance of 6 mil.

5. Finalize and Report

1. Stop execution and report the board size (90×65 mm), layer count (single-layer), mounting holes placement, and the three net classes created with their respective parameters.

# Success criteria

- The project is named “Sterilizer_Control_1L” and configured for a single-layer PCB layout (Top only).

- The board outline is a 90×65 mm rectangle with a copper‑to‑edge clearance of 1.0 mm.

- Four Ø3.2 mm M3 mounting holes are placed 5 mm from each corner at the specified coordinates.

- Three net classes (Power_24V, Power_5V, and Signals) are created with the designated widths and clearances.
