A support device used to support a circuit board includes a substrate, a plurality of protrusions, and a plurality of electrical-conductive pads. The protrusions are perpendicularly extending from a surface of the substrate and arranged as a matrix and each of the protrusions defines a threaded hole therein. The electrical-conductive pads are mounted on the substrate around the corresponding protrusions and grounding the circuit board. |
