BOARD DEVICE OF SINGLE BOARD COMPUTER

Description

FIELD OF THE INVENTION

The present invention relates to a board device, and more particularly to the board device of a single board computer.

BACKGROUND OF THE INVENTION
1. Description of the Related Art

With reference to FIG. 1 for a conventional single board computer (SBC), the single board computer includes: a cooling module having a cooling base with four locking members for locking the cooling base onto a baseboard; and a small outline dual in-line memory module (SO-DIMM) disposed on the baseboard and adjacent to the cooling module. The small outline dual in-line memory module, usually abbreviated as SO-DIMM or SODIMM, is a computer memory with integrated circuits. The SO-DIMM is similar to DIMM, but its volume is smaller and approximately equal to half of the size of the regular DIMM.

PCI Industrial Computer Manufacturers Group (PICMG) has been dedicated to the specification development and integration of computers and industrial equipment since its establishment. The main purpose of the PICMG is to provide a universal standard specification to related manufacturers. A single board computer (SBC) is a complete computer built on a single circuit board and includes one or more microprocessors, memories, input/output (I/O) devices and other functions required by a functional computer. For the single board computer, after the processor (CPU) is upgraded, the heat dissipation requirement increases, and the size of the cooling module after the corresponding upgrade increases. The entire group or the processor frame for receiving of the processor usually serves as a cooling base which is modularized and bundled to the single board computer. With reference to FIGS. 1 and 4 for the prior art and the present invention respectively, the first width W1 of the prior art is greater than the second width W2 of the present invention, because the position of locking the locking member beyond the position of the small outline dual in-line memory module (SO-DIMM) will damage the small outline dual in-line memory module (SO-DIMM), which will result in the situation of unable of locking the cooling base onto the baseboard of the single board computer after the upgrade.

The prior art is limited by different specifications of the PICMG products. Due to the limited layout space of the single board computer, the prior art has the drawback of unable to combine the cooling module easily.
