Frequently Asked Questions (FAQ)
1. What is the difference between a Gerber viewer and a PCB design software?
A Gerber viewer is a tool specifically designed for viewing and inspecting Gerber files, which are the output files generated by PCB design software. PCB design software, on the other hand, is used to create and design the PCB layout itself. Gerber viewers are used after the design process to verify the Gerber files before manufacturing.
2. Can I edit Gerber files using a Gerber viewer?
Most Gerber viewers are primarily intended for viewing and inspecting Gerber files, not editing them. However, some Gerber viewers may offer basic editing capabilities, such as modifying apertures or making minor adjustments. For more advanced editing, it is recommended to use PCB design software.
3. Are free Gerber viewers as reliable as paid ones?
While paid Gerber viewers may offer additional features and support, free Gerber viewers are generally reliable for most PCB design needs. Many free Gerber viewers are developed by reputable companies or open-source communities and undergo regular updates and improvements.
4. Can I use a Gerber viewer to check for design rule violations?
Some Gerber viewers, such as GerberLogix and ZofzPCB, offer basic design rule checking (DRC) capabilities. However, for comprehensive DRC, it is recommended to use dedicated PCB design software that includes robust DRC tools.
5. Are online Gerber viewers secure? Can I upload sensitive PCB designs?
Online Gerber viewers are generally secure, as they process and display your Gerber files within your web browser without uploading them to a server. However, if you have highly sensitive PCB designs, it is advisable to use a locally installed Gerber viewer for added security.
Conclusion
Choosing the right Gerber viewer is crucial for ensuring the accuracy and reliability of your PCB design before manufacturing. The 13 free Gerber viewers listed in this article offer a range of features and capabilities to suit various needs.
