A PCBA that includes a bare PCB comprising copper layers and dielectric layers is obtained. A connected PCBA is generated using the bare PCB, including by positioning voltage supply terminals and ground terminals that are associated with supplying power to circuit board components. Component pads are positioned, where each is electrically connected to either at least one voltage supply terminal or at least one ground terminal, but not to both. Conductive paths are configured, based at least in part on via-to-via spacing rules, including at least one voltage supply conductive path, at least one ground conductive path, and at least one data conductive path associated with data communication. Each of the circuit board components is electrically connected to at least some of the plurality of component pads, via at least some of the set of voltage supply terminals and via at least some of the set of ground terminals.

Methods and systems for configuring conductive paths in a printed circuit board assembly (PCBA) for enhanced power distribution

The present disclosure describes aspects of a conductive receptacle collar for desense mitigation. In aspects, an apparatus comprises a printed circuit board assembly (PCBA) that includes an integrated circuit with signal lines for a wired data interface. The apparatus also includes a coupling component with a receptacle for the wired data interface and an enclosure in which the PCBA is mounted. The enclosure has an opening through which the receptacle for the wired data interface is exposed. A conductive collar is disposed between an exterior surface of the receptacle and an interior surface of this opening. The conductive collar contacts the receptacle's exterior surface and the interior surface of the opening to electrically couple these respective surfaces. By so doing, the conductive collar improves grounding of the receptacle to the enclosure, which may mitigate the desense of the apparatus's wireless receivers caused by operation of the wired data interface.
