Abstract
A non-rectangular connection pad for coupling discrete components to connection pads reduces the capacitance in the connection pad area, and thus maintains a more uniform characteristic impedance along the length of the trace. The pad shape is changed to reduce the area of the pad. The reduced area reduces or eliminates change in characteristic impedance of the trace incorporating the connection pad and discrete component attached to the connection pad. An irregular pad shape may be used to decrease the soldering area of the discrete component, while still maintaining wettability of the solder. One example of such a non-rectangular connection pad is a C-shaped connection pad. Such connection pad shapes can be used on traces for high-speed circuits (e.g., PCIe, USB, SATA, and other traces carrying signals above 1 GHz).
