To open a GBR file, which is a type of Gerber file used in PCB manufacturing, you need to use specialized software designed to view or edit these files.
What is a GBR File?
A GBR file is essentially a blueprint for manufacturing a printed circuit board (PCB). It contains information about the copper layers, solder mask, silkscreen, and drill holes. These files are standard outputs from PCB design software and are sent to manufacturers to produce the physical boards.
Programs to Open GBR Files
You can open Gerber files using various programs, including several free options specifically designed for viewing them.
Based on the reference provided:
- Free Gerber Viewers:
- GraphiCode GC-Prevue
- PentaLogix ViewMate
- Gerbv
- Paid Software:
- Altium Designer (While not free, it can open Gerber files and is a comprehensive PCB design tool)
Many of the free Gerber viewers, such as those listed above, often support essential functions like viewing the different layers, checking measurements, and sometimes even printing.
Choosing the Right Software
The best choice depends on your needs:
- If you simply need to view the file to inspect it or share it, a free Gerber viewer is usually sufficient. They are easy to download and use without cost.
- If you are a PCB designer working with complex projects, professional PCB design software like Altium Designer can open GBR files as part of a broader design workflow, but it requires a paid license.
Here's a quick look at options:
| Software Name | Cost | Primary Function | Notes |
|---|---|---|---|
| GraphiCode GC-Prevue | Free | Gerber Viewer | Supports viewing, measurements. |
| PentaLogix ViewMate | Free | Gerber Viewer | Supports viewing, measurements, printing. |
| Gerbv | Free | Gerber Viewer | Open-source, supports various layers. |
| Altium Designer | Paid | PCB Design Software | Comprehensive tool that can open GBR files. |
To get started, you can typically download these free viewers directly from the software developer's website. Once installed, you can usually open the GBR file using the program's "File" -> "Open" menu option.
