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. SCH files are used for creating actual circuit board (.BRD) files.

Autodesk EAGLE (formerly known as CadSoft EAGLE) is a CAD application that professional electronics designers use to create PCB schematics and designs. EAGLE contains a schematic editor that designers use to create electronic circuit schematics, which are saved in 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 in BRD files.

NOTE: EAGLE stands for "Easily Applicable Graphical Layout Editor."

How do I 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).

What is an SCH file?

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.

What is an SCH file?

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.

What is an SCH file?

File created by the Shematic Capture Editor program included in KiCad, a tool suite used for designing PCB layouts and electronic schematics; saves an electronic schematic as it is laid out on the program's drawing canvas.

More Information

Electronic schematics are used during the schematics capture process in circuit design. Once the electronic schematic has been created, it can then be passed to the printed circuit board design process.

What is an SCH file?

An SCH file contains a schematic, or visual diagram, of a printed circuit board PCB created with ExpressSCH design software. It stores an electronic schematic as it is laid out on the program's drawing canvas and includes symbols (for logic gates) connected by lines, which represent buses.

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.
