What is an SCH file?

An SCH file contains a schematic, or visual diagram, of a PCB (printed circuit board) created with EAGLE PCB design software. It stores symbols (for logic gates) connected by lines, which represent buses. EAGLE users often create actual circuit board (.BRD) files from SCH files.

Autodesk EAGLE (formerly CadSoft EAGLE) is a CAD application that professional electronics designers use to create PCB schematics and designs. EAGLE includes a schematic editor designers use to create electronic circuit schematics and save them as SCH files.

After a designer creates a schematic, they can use EAGLE to place their schematic within a physical circuit board design. Those designs are saved as BRD files.

NOTE: Prior to version 6, EAGLE SCH files were saved in a proprietary text and binary format. Version 6 and later SCH files are saved in the XML format.

How to open an SCH file

You can open an SCH file in a variety of PCB design applications, including:

If you do not have access to any of the above applications, the easiest way to view the circuit board schematic contained within an SCH file is to upload it to Altium 365 Viewer, a free, online CAD file viewer (web).

Schematic file created and used by gEDA, a collection of tools used to design PCB layouts and electronic schematics; contains data that makes up the schematic; includes the gEDA/gaf format version, pictures, and XY coordinates for nets, buses, and components.

More Information

Electronic schematics consist of a collection of symbols, or components, nets, and buses. They are used during the schematics capture process in circuit design and once it has been created, it can then be passed to the printed circuit board design process.

File used by Strater, a program used for visualizing subsurface borehole and well log data; specifies the nomenclature (keywords, data range, lithology, etc.) and the display properties (line, text, symbol, fill, etc.) for design elements that use the nomenclature; enables designs to be created according to standards.

More Information

Strater schemes can be created and edited in the Scheme Editor, which is accessed by selecting Tools → Scheme Editor... from the application menu.

The ExpressSCH Schematics (SCH) file type is one of several schematic file types that use the .sch file extension. The ExpressSCH file type is a proprietary file format that is not supported by other Schematics programs. You can only open an ExpressSCH file with ExpressSCH software.

To open an SCH file with ExpressSCH, select File → Open.... To export an SCH file to a .BMP file with ExpressSCH, select File → Export schematic image....

Once a user finishes designing an electronic schematic, he passes it to the PCB design process. After the PCB is created, it is passed on to the manufacturing process to be assembled and put to use in various electronic products.

NOTE: ExpressSCH is included with the ExpressPCB software package.
