  • Pad patterns
    Patent number: 10349517
    Abstract: In one implementation, a printed circuit board (PCB) includes a plurality of pads that form a pad pattern on the PCB. In that implementation, the plurality of pads include a group of load pads, a dummy pad, and a false pad. The group of load pads act as contact points to establish an electrical path between a first circuitry and a second circuitry. The dummy pad is coupled to a via that floats electrically and the false pad is coupled to a third circuitry.
