Getting Started with PCB Design

Why Design Your Own PCB?

// TODO: Replace with real blog content

If you've ever built a circuit on a breadboard and wished you could make it permanent, cleaner, and more reliable — PCB design is the next step. A custom PCB replaces messy wiring with precise copper traces, making your circuit compact, reproducible, and professional-looking.

Choosing Your Tool

For beginners, I recommend **KiCad** — it's free, open-source, and has a thriving community. The learning curve is moderate, but the payoff is enormous. Other options include EasyEDA (browser-based, good for quick projects) and Altium Designer (industry standard, expensive).

The Workflow

**Schematic capture** — Draw your circuit diagram with proper symbols and connections

**Component selection** — Choose real parts with specific footprints

**PCB layout** — Place components and route copper traces

**Design rule check** — Verify your design meets manufacturing constraints

**Generate Gerbers** — Export manufacturing files

Your First Board

Start simple. A breakout board for a single IC is a perfect first project. You'll learn the full workflow without the complexity of a multi-component design.

Common Mistakes

Forgetting decoupling capacitors near IC power pins

Making traces too thin for the current they carry

Ignoring the manufacturer's minimum trace width and spacing

Not adding mounting holes
