Abstract:
Certain aspects of the present disclosure generally relate to a circuit board with ground vias offset from associated ground bumps. One example circuit board generally includes a first signal connection terminal configured to connect a signal line of the circuit board to an integrated circuit (IC); a ground plane having a first ground connection terminal disposed adjacent to the first signal connection terminal, the first ground connection terminal being configured to provide a ground connection between the ground plane and the IC; and a first ground via associated with and disposed adjacent to the first ground connection terminal and coupled to the ground plane, wherein, from an overhead view of the circuit board, the first ground via is located at a position that is offset from a first axis on which the first signal connection terminal and the first ground connection terminal are disposed.
