#89520 - Ground plane Responding to: ???'s previous message |
Mehdi said:
What is meaning solid ground plane ? 'Solid ground plane' is the concept of using one whole layer of printed circuit board for 0V only, means ground. This ground layer shall be a plane, as solid as possible, means this ground plane should be as continuous and unbroken as possible. Such a solid ground plane shows lowest inductance for all the signal return currents and the power supply decoupling measures. Because of this, ground noise of a solid ground plane is much much smaller than you will observe it with narrow ground tracks. An ideal solid ground plane in complex applications can only be achieved by the use of multilayer board (4 layers for instance). But even with bi-layer or single-layer boards the concept of a ground 'plane' should be used, although it will be hard to realize it without many interruptions... Kai |
