6 FAQs about [Three-layer ball capacitor grounding]
How do I connect a capacitor (C27) to a ball A12?
Connect capacitor (C27) directly to ball A12 (DCO_LDO_OUT). Using a via, isolate the capacitor (C27) ground from the layer 1 ground and connect the capacitor (C27) ground directly to the layer 2 solid ground. When designing the RF path, follow the placement and layout rules described in this section.
Why is grounding important in a PCB?
Grounding in a PCB can be considered as one of the most important system level consideration in complex systems. The grounding strategy and implementation on PCB can be the deciding factor for that design to pass EMC. Before going any further, it is important to understand how energy flows in a PCB.
How to increase the effectiveness of decoupling capacitors?
A special layout of decoupling capacitor is proposed to increase the effectiveness of the decoupling capacitors by taking maximum advantage of the mutual inductance between interconnect vias with two decoupling capacitors placed in a pair, and two pairs of power and ground vias placed in alternating directions as close as possible.
How to establish a ground in a circuit board?
A solution is to create a circuit board that establishes a ground with the characteristics of node_G. The principle is simple—the circuit trace from the input ground terminal to the ground side of R1 should be a clear path with no connections to contaminating sources of current along the way (figure 2).
What if a 0 impedance grounding conductor was 0 V?
The “chassis ground”, if grounding conductors had 0 Ω impedance, would also be 0 V—but, unfortunately, it never is. Yet there are still systems that are sufficiently insensitive to ground potential differences. They use the chassis for the signal and power returns. At one time, this was the way cars had been wired.
What is the fundamental rule for grounding?
The fundamental rule for grounding is depicted in Figure 1. By “ground” I mean the common 0 V potential to which signals are referenced. The “chassis ground”, if grounding conductors had 0 Ω impedance, would also be 0 V—but, unfortunately, it never is. Yet there are still systems that are sufficiently insensitive to ground potential differences.
