CoreExpress

COMs integrate CPU, memory, graphics, and BIOS, and common I/O interfaces.

[2] CoreExpress modules are mounted on a custom carrier board, containing the peripherals required for the specific application.

[7] Initially adopted by the German LiPPERT and the Swiss company DIGITAL-LOGIC[8] (which has meanwhile been bought by Kontron),[6] it was later backed up by more than eight vendors[6] including Syslogic.

This simplifies mechanical design for the system builder, but can be less efficient than a complete purpose-built thermal solution.

In a complete system, heat spreaders can be part of the electromagnetic interference containment design.
