The Tools component would help to visualise coa imaging opportunities close formation flying mission constraints special analysis; - Ground trace

In this case, however, the excitation of common-mode currents on the DC supply loop produces the in-phase x-directed components and out-of-phase y-directed components between the power trace and the ground trace
Isolation and crosstalk can be mitigated by simply placing a ground trace
between two signals.
For example, if an engineer plans to use individual cans to separate two cavities, each can needs its own ground trace
with space between them.
When the adjacent ground trace
is brought close, it will intercept these fringe fields, but they will also go to ground (FIGURE 2).
g] denote the inductance of the power and ground trace
of DC supply loop on PCB and the element values were derived by using Ansys-Ansoft Q3D Extractor.
Multi-cavity shields can isolate tightly-packed components, but the shields are only as effective as their mating to the ground trace
on the PCB.
The flatness of the SE data at the lower frequencies can be explained by the fact that apertures in the shield walls, the attachment points to the ground trace
, and the vias that connect the ground trace
to the ground plane are all in the near field of the radiators.
The GORE-SHIELD[R] SMT EMI gaskets can be used as a RF grounding pad or interconnect as well as in EMI shielding applications where the gaskets are placed along the ground trace
on a PCB.
It's best to run a clock net and then have a ground trace
shielding the entire path of the clock trace.
The board-level shield is typically a box-like metallic component that is placed over the component(s) to be shielded and then soldered to a ground trace
on the board to effect shielding.
These gasket pieces or building blocks are easily arranged in whatever gasket configuration is required, installed directly on the PCB ground trace
with standard surface-mount technology (SMT) pick-and-place machines, and soldered with standard reflow equipment.
