What is an SCH file?
A .SCH file is an electronic circuit schematic document. It maps the connections between electronic components on a printed circuit board. Engineers use these files during the design phase of electronic hardware. Many different Electronic Design Automation (EDA) programs create these files. Because many programs use the .SCH extension, your file could belong to Autodesk EAGLE, KiCad, Altium Designer, ExpressPCB, [Cadence OrCAD], or even be a gEDA Schematic File created by [gEDA].
How to open SCH files?
Because .SCH has multiple possible meanings, it is difficult to know which program will open it. viewer.online/sch analyzes .SCH files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If you need to edit the file, you must install the specific software that created it.
Software and tools
Notable tools for editing schematics include Autodesk EAGLE, KiCad, Siemens PADS Logic], and [Altium Designer. If you need to share your design with someone who does not have CAD software, you should convert the file. We recommend file conversion to sensible target formats on convert.guru. You can often convert .SCH files to PDF, PNG, or Gerber formats.
Summary
Because .SCH files use the known XML format, viewer.online/sch can safely open and display them online, eliminating compatibility problems.
