    摘要: An electronic device is provided and includes a circuit board and a casing. The circuit board includes a plate body, a perforation and a ground wire. The perforation penetrates through the plate body, the ground wire is electrically coupled with the plate body and crosses over the perforation. The casing includes a bottom plate and a clamping structure. The clamping structure is disposed on the bottom plate and includes a first clamping part and a second clamping part. The circuit board is disposed in the casing, and the clamping structure penetrates through the plate body through the perforation, so that the circuit board is positioned on the casing, and the ground wire is clamped by the first clamping part and the second clamping part of the clamping structure. Consequently, the circuit board is grounded with the casing.

    摘要: 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.

    摘要: An electronic device includes a casing, a circuit board and a grounding assembly. The circuit board has a first surface and a second surface, wherein an input terminal and an output terminal are disposed on the second surface. The grounding assembly comprises a conducting terminal, a first grounding element and a second grounding element. The conducting terminal is disposed on the first surface of the circuit board, and the first grounding element is disposed adjacent to the conducting terminal. The first grounding element penetrates the circuit board and electrically couples with the conducting terminal and the casing, and the second grounding element correspondingly penetrates the circuit board and the conducting element, so that a first portion of the second grounding element electrically couples with the input terminal and the output terminal of the circuit board, and a second portion of the second grounding element electrically couples with the conducting terminal.
