ROU File – What is .rou file and how to open it?
ROU File Extension
Gerber Route File – file format by N/A
ROU (Gerber Route File) is a file format used in the printed circuit board (PCB) industry to define the routes that a routing machine will take to create the board. It is a text-based format that contains a list of commands that specify the shapes and sizes of the routes, as well as the order in which they will be created.
Definition of ROU File
A ROU file, short for Gerber Route File, is a file format that describes the routing paths for printed circuit boards (PCBs). It is used in the manufacturing process of electronic devices to provide instructions on how to create the copper traces and other circuitry on the PCB. ROU files are essential for ensuring the accuracy and efficiency of PCB production.
Structure and Content
ROU files are ASCII text files that contain a series of commands and data that define the routing paths. These commands specify the width, shape, and location of each trace, as well as the drill size and spacing for vias. Additionally, ROU files can include information about the board’s dimensions, layer structure, and solder masks. The data in ROU files is typically organized into sections, each of which corresponds to a specific layer of the PCB. This structure allows for easy editing and modification of the routing paths, making it convenient for engineers to make adjustments during the design process.
Software Compatibility for ROU Files
ROU files, also known as Gerber Route Files, are specialized files that contain instructions for manufacturing printed circuit boards (PCBs). These files are primarily used by CAM (computer-aided manufacturing) software and are essential for the fabrication of electronic components. To open and edit ROU files, specific software programs are required. Some of the most commonly used programs include:
- Gerber File Viewers: These programs allow users to view and inspect the contents of ROU files. Examples include Gerbv, Gerber Viewer, and GC-Prevue.
- CAM Software: Professional CAM software packages, such as Altium Designer, Cadence Allegro, and Mentor Graphics Expedition, can open, edit, and generate ROU files as part of the PCB fabrication process.
Additional Considerations
In addition to the software requirements, opening ROU files may require additional considerations:
- File Location: ROU files are typically stored in the PCB design data folder or in a separate location specified by the CAM software.
- File Association: The operating system may not automatically associate ROU files with the appropriate software. Users may need to manually configure the file association settings to ensure that ROU files are opened with the desired program.
- File Integrity: ROU files should be checked for errors and inconsistencies before being used for manufacturing. Errors in the file can lead to incorrect PCB fabrication.
ROU File Format
A ROU file, also known as a Gerber Route File, is a computer-aided manufacturing (CAM) file format used in the printed circuit board (PCB) industry. It contains data about the routing paths for a PCB, including the dimensions and shape of the paths, as well as information about the tools and materials used to create them. Gerber Route Files are an essential part of the PCB manufacturing process, as they provide the instructions for routing the copper traces and other features on the circuit board.
Structure and Contents of ROU Files
ROU files are text-based and use a specific syntax to describe the routing paths. They typically include commands for defining the starting and ending points of the paths, the width and shape of the paths, and the tools and materials used to create them. ROU files also contain information about the size and shape of the circuit board, as well as the location of any vias or other features. This information is crucial for ensuring that the routing paths are accurate and that the PCB is manufactured correctly.
