Abstract:
1. A substrate pad structure for connecting a lead connecting portion of an electronic device to a substrate, the substrate pad structure comprising: a first pad portion and a second pad portion that are arranged on the substrate at corresponding positions of two end regions of the lead connecting portion, which has a continuous oblong shape, and a third pad portion that is arranged between the first pad portion and the second pad portion and is distanced from the first pad portion and the second pad portion; wherein a space portion is provided between the first pad portion and the second pad portion, and the lead connecting portion includes a non-connected region located at a corresponding position of the space portion, only one of the first and second pad portions is an electrical connection terminal, the other of the first and second pad portions is not the electrical connection terminal, is configured to reinforce a mechanical strength of a connection between the lead connection portion and the substrate, and adjust a characteristic impedance of the substrate pad structure, and the third pad portion is arranged parallel to a longitudinal direction of the lead connecting portion, and an entirety of the third portion is deviated in a transverse direction relative to the longitudinal direction of the lead connecting portion so that only half of the lead connecting-portion in the transverse direction is connected to the third pad portion.
