How to Open PCB File : The Comprehensive Guide

Similar to computer files, a Printed Circuit Board (PCB) file is an electronic file that contains essential data about an electronic circuit board’s design, function, and performance. A PCB file is considered the nerdy cousin of computer files due to its specialized functionality and technical terminology.

If you are working in the electronics design field, understanding PCB files is essential as it is the primary file format that deals with files related to circuit board design. Even though computer files and PCB files have some similarities, the latter requires professionals with specialized knowledge and skills in electronics design to open, edit, or recover.

In this article, we will explore why it is essential to bother with PCB files and how to open them to work with PCB designs with ease. Stick around to find out!

Understanding PCB File Types

PCB (Printed Circuit Board) design files come in different formats. Each file type has its unique characteristics, which sets it apart from others. Understanding these differences is crucial if you want to open and work on a particular PCB file accurately.

Here are some of the most common PCB file types:

Gerber Files

Gerber files are the most popular and widely used file format for PCBs. They are a 2D file format that contains all the necessary information for fabricating the PCB, such as the copper layers, solder mask, silkscreen, and drill data. Gerber files can be opened using various PCB design software programs, including Eagle, Altium, and KiCAD.

ODB++ Files

ODB++ is a proprietary file format for PCB design. It’s a complete CAD-to-CAM data exchange format that contains all the information required for the manufacturing process, including PCB layout, netlist, and component data. ODB++ files are widely supported by various software programs, including Altium, Cadence, and Mentor Graphics.

Eagle Files

Eagle is a popular PCB design software that uses its proprietary file format. Eagle files are saved with the .brd file extension. These files are compatible with the Eagle software and can be opened using its built-in viewer. However, there are third-party viewers available for opening Eagle files, including PCBWeb.

Altium Files

Altium Designer is a popular software program used for designing PCBs. Altium files are saved with the .PcbDoc file extension, contain all the necessary component placement, routing information, and layer stack up. Altium Designer is the only software program that supports opening Altium files because it uses its proprietary file format.

Other File Types

Other PCB file types include P-CAD, DipTrace, OrCAD, and Kicad. Each file type has its distinct characteristics and is typically associated with its software program. However, various software programs can open multiple file types.

Understanding the different file types for PCB design is essential for working accurately with the relevant software. Each file type has its unique characteristics, and knowing which software programs support which file type can save you a lot of time and effort. By using the right software program for each type of file, you can ensure that you can open and work effectively on the required PCB design file. 

Software Programs for PCB File Opening

When it comes to opening PCB files, there are several software programs available, each with its unique features and benefits. The most popular programs for PCB design include Eagle, Altium, KiCad, and more. Let’s take a closer look at these programs and what makes them stand out.

Eagle is a widely used software program in the PCB design world. It is beginner-friendly and has an intuitive user interface that makes it easy to use even for those who are new to PCB design. The software comes with an extensive library of electrical components, making it easier to design circuits quickly. However, Eagle has some limitations when it comes to complex designs, and the free version has limited functionality.

Altium is another popular software program used by many PCB designers. It has a comprehensive library of electrical components, making it easy to create complex and intricate designs. Altium also offers features like automated routing, which significantly cuts down the time spent on designing a circuit. However, Altium is quite expensive, making it less accessible to beginner designers.

KiCad is an open-source software program for creating electronic schematics and PCB designs. It has a user-friendly interface, making it easy to use even for those without any prior experience in PCB design. KiCad is also compatible with Windows, Mac, and Linux operating systems, making it a versatile option. However, it has limited library options which could make designing more challenging.

Now that you know about some of the top PCB software programs let’s explore how to download and install the software like a pro. To download and install the software correctly, you first need to visit the official website of each program and select the appropriate version for your computer. After downloading the software, you need to follow the installation instructions carefully. It is essential to read the instructions thoroughly and ensure that you’re not skipping any essential steps.

Common Issues and Troubleshooting

If you’re having trouble opening your PCB file, don’t worry – there are a few common issues that can be easily fixed with just a bit of troubleshooting. Here are some tips for identifying and resolving some of the most common issues:

1. File Format Compatibility: PCB files can come in various file formats such as .PCB, .BRD, and .LAY. Some PCB design software may require specific file formats, so make sure to check if your software is compatible with your PCB file format. If it’s not, you can always try converting your file format into a more compatible one.

2. Corrupt File: If your PCB file won’t open, it may be due to file corruption. Try opening the file on a different computer or using another software. If the file still won’t open, try recovering the file using file recovery tools or reloading a previously saved version of the file.

3. Application Settings: Review your application settings to make sure that the correct file type is set as the default for your design software. Some software will enable you to specify which file extensions or types can be opened so go to your settings and add the file type you want to use.

4. Component Libraries: If you are working with complex projects with numerous components, ensure that you have all the necessary component libraries installed before trying to open the file. The software needs access to these components to open the PCB file.

5. File Associations: Make sure that your operating system is correctly associating the file extension with the appropriate application. Sometimes, an update or change to your system can cause this association to break.

By troubleshooting these potential issues, you should be able to get your PCB file open in no time. However, if you’re new to PCB design, it’s important to remember that there may be other issues related to design data files, drill data files, and manufacturing files that could cause problems. In these cases, it’s best to reach out to an online community of PCB developers or consult with an expert in electronics design. Don’t be afraid to ask for help!


As you can see, opening PCB files is not as hard as it may seem. You just need to have the right software and follow some simple steps.

By learning how to open PCB files, you can access the design and layout of printed circuit boards, which are essential components of many electronic devices. You can also edit, modify, or create your own PCB files if you have the skills and tools.
