    Abstract: A high-speed transmission circuit comprises, as part of a signal path, a connector pin disposed on a pad that comprises an unused pad region. The unused pad region is not considered part of the signal path but is part of a resonant sub-circuit. In various embodiments, by properly adjusting the dimensions of the pad region and other structures in the high-speed transmission circuit, resonant frequencies of the sub-circuit are shifted to a frequency range that is outside of the frequency range of interest in the signal path, thereby, reducing insertion loss and increasing signal integrity without compromising mechanical stability.

    Abstract: An electronic device with a plug includes a casing, a connection member and a circuit board. The connection member is combined with the casing. The connection member includes a first surface, a second surface, at least two perforations and at least two insertion parts. The first surface and the second surface are opposed to each other. The at least two perforations run through the first surface and the second surface. The at least two insertion parts are fixed on the first surface, protruded externally from the first surface and aligned with the corresponding perforations. The circuit board is accommodated within an accommodation space of the casing, and includes at least two conducting terminals. The conducting terminals are penetrated through the corresponding perforations from the second surface of the connection member, received within the corresponding insertion parts and partially protruded out of the corresponding insertion parts.
