MOTHERBOARD AND ELECTRONIC DEVICE EMPLOYING THE SAME

摘要

A motherboard for an electronic device includes a main circuit board, an interface, and a sub-circuit. The main circuit board holds a plurality of heat generating element, and the sub-circuit board is electrically connected to the main circuit board through the interface. The sub-circuit board includes a connecting board and a holding board for holding heat generating elements. An end of the connecting board is electrically connected to the main circuit board through the interface, and another end of the connecting board is electrically connected to the holding board. The holding board and the main circuit board are located at opposite ends of the connecting board, and the holding board is spaced with the main circuit board in parallel.
