The IPC-2581 Viewer is a free software application that enables users to visualize and inspect IPC-2581 PCB files. It is a standard for exchanging PCB design data among different software tools and systems. Users can easily access and visualize various layers, pads, traces, drills, and nets in the PCB design. They can also adjust the visibility and colors of these elements for better visual representation and analysis.

It’s free
This means that designers and users without access to specialized software can still visualize and inspect IPC-2581 PCB files at no additional cost. This provides broader accessibility and facilitates collaboration across different teams and organizations.

Purpose of IPC-2581

  • Interoperability: IPC-2581 enables a smoother exchange of PCB design data between different software platforms and systems. It reduces the need for manual file conversion between different formats, minimizing the risk of errors and data corruption.
  • Collaboration: By adopting a common standard like IPC-2581, designers, manufacturers, and suppliers can easily share PCB design files without hindrances. This improves collaboration among different teams and organizations, even if they use different software tools to create the design.
  • Security and Accuracy: IPC-2581 ensures that all essential design data is preserved during the exchange process, reducing the risk of data degradation or loss. This contributes to higher quality and accuracy of the finished PCB products.
  • Time Saving: By using IPC-2581, designers and engineers can save time as they no longer need to spend time converting and adapting design files between different formats. This increases productivity and speeds up the product development cycle.
Improve collaboration with supply chain companies through IPC-2581


One of the most valuable features of IPC-2581 Viewer is its ability to visualize various elements in the PCB design. Users can easily adjust the visibility and colors of layers, pads, traces, drills, and nets to gain a better visual representation of the design. This makes it easier to analyze and understand complex PCB designs.

Hierarchical Data Navigator, Inspection, and Analysis
IPC-2581 Viewer also offers a range of tools for inspection and analysis. It includes a hierarchical data navigator that allows users to navigate through the different layers and components in the design and access detailed information. Interactive inspection tools and usage reports help identify any issues or errors in the design and enable a thorough inspection of PCB files.

Measurement Tools
Users can make precise measurements on the PCB design by measuring distances from point to point, edge to edge, and center to center. This is useful for assessing dimensions and distances in the design and ensuring that all components are correctly placed.

Markup and Communication
The markup feature allows adding annotation text to the design. This makes it easy to communicate any issues or instructions to other team members. Markups can be used to point to specific areas of the design or provide guidance for changes or improvements.
