GBR File Extension
Gerber File – file format by Ucamco
GBR (Gerber File) is a file format used in the printed circuit board (PCB) industry to describe the layers of a PCB. It is a vector-based format that can be used to represent the different layers of a PCB, including the copper layers, the solder mask layers, and the silkscreen layers. GBR files are typically used to manufacture PCBs, and they can be imported into a variety of PCB design software programs.
Gerber Files: An Overview
A Gerber File (GBR file) is an ASCII-based file format specifically designed for use in the printed circuit board (PCB) industry. Developed by Ucamco, a leading provider of CAD/CAM software for the PCB industry, GBR files serve as the industry standard for transferring PCB design data from design tools to manufacturing machines. They contain instructions for creating the copper layers, solder mask, silkscreen, and other elements of a PCB.
Structure and Usage of Gerber Files
GBR files consist of a series of commands and data that define the geometry and characteristics of the PCB. Each command starts with a letter identifier, followed by parameters that specify the specific operation or shape. For example, the “G01” command represents a movement command, while the “X” and “Y” parameters define the coordinates of the movement. Additionally, GBR files may include information such as layer names, aperture sizes, and color data. These files are widely used in PCB manufacturing because they are compatible with a wide range of software applications and manufacturing machines, ensuring seamless data transfer and accurate production of PCBs.
Using Software
Open GBR files using specialized software such as CAMtastic, GC-Prevue, or Altium Designer. These programs provide comprehensive support for Gerber files, allowing users to view, edit, and export the data. They often include features for optimizing Gerber files for manufacturing, ensuring precision and minimizing production errors.
Online Converters
Alternatively, online converters like GerbView and Gerber2PNG can convert GBR files into more accessible formats. GerbView provides a web-based interface for viewing and inspecting Gerber files, while Gerber2PNG converts GBR files into PNG images that can be easily shared and viewed. This approach is particularly useful for quick previews or sharing files with non-technical users.
Gerber File (GBR)
A Gerber file is a standard format for describing the printed circuit board (PCB) artwork. It is a vector-based format that stores the outlines of the copper traces, solder masks, and other features of the PCB. Gerber files are used to manufacture PCBs by photolithography.
The Gerber format was developed by Ucamco in the 1960s. It is a simple and efficient format that is widely supported by PCB design and manufacturing software. Gerber files are typically stored in ASCII format, but they can also be stored in binary format.
Gerber files are used to define the following elements of a PCB:
- Copper traces
- Solder masks
- Silkscreen
- Drill holes
- Component placement
Gerber files are essential for the manufacture of PCBs. They provide the necessary information to the photolithography process, which creates the copper traces and other features of the PCB.
