Navigation:  Designing a PCB with the DEX PCB Designer >

Getting Started

Starting with PCB (Printed Circuit Board) design can be both exciting and daunting, especially if you're new to the field of electronics or haven't had much experience beyond basic concepts. PCBs are fundamental to modern electronics, and understanding how to design them is an essential skill for many engineering roles. Here's a guide to help you begin your journey into PCB design:

Understand the Basics of Electronics and Circuits

Familiarize yourself with basic electronics concepts, such as current, voltage, resistance, Ohm's Law, and Kirchhoff's Laws.

Learn about different electronic components (resistors, capacitors, diodes, transistors) and how they're used in circuits.

Learn About PCBs

Understand what a PCB is and its role in electronic devices.

Learn about the different layers of a PCB, including the silkscreen, solder mask, copper layers, and substrate.

Get familiar with the terms used in PCB design like traces, pads, vias, footprints, and more.

Choose the Right Design Software

Re and select a PCB design tool. This manual is about using DEX. It is user-friendly and has communities around it that can help you when you're stuck.

Install the software and familiarize yourself with its interface. Learn how to start a new project, create schematic diagrams, and build PCB layouts.

Start with a Simple Project

Choose a beginner-friendly project. Starting with a simple circuit, like a blinking LED or a basic audio amplifier, can help you understand the process without overwhelming you.

Draw the schematic in your design software. Place components and connect them to recreate the circuit diagram on your screen.

Create the PCB Layout

Once your schematic is complete, proceed to design the PCB layout. This step involves placing the physical components and routing the connections between them.

Learn about design considerations like signal integrity, trace width, current-carrying capacity, and avoiding cross-talk.

Learn About Design Rule Check (DRC)

DRC is a critical step to ensure your design complies with the manufacturing capabilities and to avoid errors in the final product.

Understand common design rules and how to apply them in your software.

Prepare for Manufacturing

Learn how to export your PCB design files. You'll typically need to generate Gerber files, a drill file, and sometimes a pick-and-place file for assembly.

Understand the Bill of Materials (BOM) and how to compile one for your project.

Order Your PCBs

Research and choose a PCB manufacturer. For your first project, look for services that cater to hobbyists or offer prototype quantities.

Submit your design files and order your first batch of PCBs.

Assembly and Testing

Once you receive your PCBs, you'll need to solder on the components. Learn basic soldering techniques if you haven't already.

After assembly, test your circuit. Learn about common debugging techniques for when things don't work as expected.

Continue Learning

PCB design is a vast field, and there's always more to learn. As you gain confidence, take on more complex projects, learn about advanced topics like impedance matching, high-speed design, and EMC/EMI considerations.

Join communities, participate in forums, and don't hesitate to ask questions.

Document and Share Your Work

Documentation is a crucial part of the design process. Keep records of your design process, decision-making, and any iterations on your design.

Sharing your work with the community can help you gain feedback and improve.


Starting with PCB design is a step into a broader world of electronics and product development. Take it step by step, don't rush the learning process, and remember that making mistakes is part of learning. As you grow more comfortable with the basics, you can delve into more complex projects and aspects of PCB design.
