A .SCH file is a CAD schematics file that contains schematic diagram of the electronic parts. The SCH file represents the electronic design in a graphical format connecting various parts and devices of an electronic circuit. The SCH file format is supported by various CAD and CAE programs, and the SCH file created by the CAD and CAE applications are considered as a proprietary file associated with the specific application. The SCH file created for one application may not be compatible with other applications.
Below you will find an index of software programs that can be used to open SCH files divided into 3 categories according to system platform supported. SCH files can be encountered on all system platforms, including mobile, yet there is no guarantee each will properly support such files.
Problems with accessing SCH may be due to various reasons. On the bright side, the most encountered issues pertaining to CAD Schematics Format files aren’t complex. In most cases they can be addressed swiftly and effectively without assistance from a specialist. We have prepared a listing of which will help you resolve your problems with SCH files.
Problems with opening and working with SCH files are most probably having to do with no proper software compatible with SCH files being present on your machine. The most obvious solution is to download and install EAGLE or one to the listed programs: OrCAD PCB Designer, EAGLE Layout Editor, CIRDCAD. Above you will find a complete listing of programs that support SCH files, classified according to system platforms for which they are available. If you want to download EAGLE installer in the most secured manner, we suggest you visit website and download from their official repositories.
If you already have EAGLE installed on your systems and SCH files are still not opened properly, check if you have the latest version of the software. Software developers may implement support for more modern file formats in updated versions of their products. If you have an older version of EAGLE installed, it may not support SCH format. The latest version of EAGLE should support all file formats that where compatible with older versions of the software.
If you have the latest version of EAGLE installed and the problem persists, select it as the default program to be used to manage SCH on your device. The method is quite simple and varies little across operating systems.
Change the default application in Windows
Change the default application in Mac OS
Should the problem still occur after following steps 1-3, check if the SCH file is valid. It is probable that the file is corrupted and thus cannot be accessed.
If the file is infected, the malware that resides in the SCH file hinders attempts to open it. Immediately scan the file using an antivirus tool or scan the whole system to ensure the whole system is safe. If the SCH file is indeed infected follow the instructions below.

Try downloading the file again.
Sometimes in order to access files user need to have administrative privileges. Switch to an account that has required privileges and try opening the CAD Schematics Format file again.
If the system is under havy load, it may not be able to handle the program that you use to open files with SCH extension. In this case close the other applications.
Up-to-date system and drivers not only makes your computer more secure, but also may solve problems with CAD Schematics Format file. It may be the case that the SCH files work properly with updated software that addresses some system bugs.
