PCB Design Showcase

Project Scope

The aim of this project was to design and implement a 4-layer printed circuit board (PCB) using Autodesk Eagle software. The objective was to create an efficient, noise-managed, and compact PCB while maintaining a functional and aesthetically organized design.

My Role

I was responsible for the entire PCB development process, including schematic design, component placement, layer routing, and final layout. I also conducted design rule checks (DRC) and oversaw soldering and assembly to ensure proper functionality.

Work Process

Schematic Design

• Created logical connections between components.
• Verified schematic accuracy to avoid errors.

Component Placement

• Positioned components to minimize trace lengths and optimize performance.

Layer Routing

• Top and Bottom Layers: Used for signal traces.
• Inner Layers: Reserved for power and ground planes to reduce interference.

Design Rule Check (DRC)

• Ensured compliance with trace widths, clearances, and component placements.

Assembly and Testing

• Used soldering tools to populate the board and test its functionality.
