PCB Design: How to Create a Printed Circuit Board From Scratch

To design a Printed Circuit Board (PCB), you need to draw holes, pads, and wires for your circuit.

When you’re done drawing the board, you can either send the design to a manufacturer that will make it for you (it’s actually pretty cheap) – or you can etch it yourself at home.

This skill is called PCB design and it’s easier than many think.

In this guide, I’ll lay out all the steps for you. And once you’ve gone through these steps one time, the second time everything is much easier.

Step 1: Create Or Find A Circuit Diagram

Before you start drawing wires and stuff, you need to know what circuit you want to build. So you need a circuit diagram.

You can either find one that someone else has made, or you can design your own from scratch.

I recommend starting with something simple. Like this blinking LED circuit:

Once you have your circuit diagram, move on to step 2.

Step 2: Draw Your Schematics

First, you need to install a PCB design software.

I highly recommend KiCad for making your PCB. It’s free and it’s really good. I’ve also created a step-by-step KiCad tutorial for beginners. But the following steps are more or less the same, no matter what software you use.

Create a new project. Then draw the schematics from the circuit diagram you found in Step 1.

When you think you’re finished, run the Electrical Rules Checker (ERC) to see if you’ve made any errors.

Step 3: PCB Design – Your Board Layout

Now it’s time to draw the board. You need to transfer your schematic diagram into a drawing of your printed circuit board.

This isn’t as hard as it might sound. Because the software will compare what you are drawing to the schematics file. And it will help you create the same connections.

An important decision here is what footprint you should choose for the components. Through-hole or surface mount?

Through-hole components are the easiest to solder. I recommend through-hole for beginners. Surface mount components are smaller, so they take up much less space. But smaller also means it could be harder to solder. That said, it just takes a bit of practice to get used to surface mount components. So if you’re up for the challenge, then go for it.

Take your time, and make sure it looks good ;) Follow the design guidelines for drawing circuit boards.

When you’re done, run the Design Rules Checker (DRC) to see if you’ve made any errors.

Step 4: Get Your PCB Made

When you’re finished drawing your PCB design, you need to get the design made. You could etch your PCB at home, but my preferred way is to just order a PCB from one of the many PCB manufacturers out there.

It’s really not expensive. For example, it’s not uncommon to see offers of 5 copies of your board for less than $5 USD! And you don’t have to mess around with chemicals on your own.

These are some of my favorites:

The classic way of sending a board layout to a manufacturer is by creating Gerber files from your design. But some (ex. OSH Parks) also accept KiCad files directly so that you don’t have to do any conversion.

Step 5: Order Components

It usually takes a bit of time before your PCB is ready. So while you wait, make sure you have all the components you need. There’s nothing worse than receiving a fresh PCB, just to realize you are missing some key components!

I’ve put together a list of shops where you can buy electronic components online. The shops in that list I’ve either used myself, or I know someone who has used them.

Step 6: PCB Assembly – Soldering the Components to the Board

You have your circuit board, fresh out of the printer. You have ordered and received the component. Now it’s time for the most exciting part – PCB upbringing!

Prepare your workbench and get your soldering tools out. Lay out the components and the PCB on your workbench.

Have your computer with the PCB Design close by so that you can check the orientation and value of components if needed. If that’s not possible, print out the schematic with values and the board layout.

Make yourself a cup of coffee, then get started soldering!
