Abstract: The three-dimensional disposition structure of an electric board component, comprising an electric board and several elements. The several elements includes several plane elements, which have at least one short connection leg, and several elevated elements, which have at least one long connection leg. Wherein, the plane element is welded onto the electric board and its bottom is close to the electric board, and the elevated element is welded onto the electric board and its bottom is above the plane element.

Abstract: A Wireless Mouse Receiver Device, which comprising: an upper shell body, a lower shell body and an interior structure. The interior of upper shell body has several connection holes. The interior of lower shell body has several connection pillars. And, the interior structure, arranged between the upper shell body and lower body, includes: a connection head, which may be connected to the needed apparatus, a first electric board, on which is arranged with connection head and has several first welding points, and a second electric board, which has several second welding points and comprising: several plane elements, which has several short connection legs that is close to the second electric board, several elevated elements that has several long connection legs welded onto the second electric board and is above the plane element. Wherein, the first electric board is perpendicular to the second electric board and both are welded together by welding points to transmit signal.
