All printed circuit boards need a steady supply of voltage to function. In this post, we’ll discuss power and ground planes in PCBs, including best practices for incorporating them into your PCB designs and how OrCAD X can aid in designing them. How Do You Know When to Use a Power ...
Using porous power and ground plane materials in PCBs allows liquids (e.g., water and/or other solvents) to pass through the power and ground planes, thus decreasing failures in PCBs (or PCBs used as laminate chip carriers) caused by cathodic/anodic filament growth and delamination of ...
Learn how to use the gridded ground technique to reduce noise in a double-sided PCB. The ground planes of a multi-layer board can significantly improve the noise performance of a circuit. With a double-sided board, we usually cannot have a ground plane and we expect to have more ...
the PCB designer can use ground planes to help control the electrical performance of the board. By using a ground plane between two active signal layers, thecrosstalk between the signalson those layers can be eliminated. And by making sure that there is an uninterrupted signal return path on ...
PCB ground planes can have a major influence on the electromagnetic behaviour of electronic equipment. Correct design of such ground planes is therefore vital for EMC considerations, and accurate simulation of this behaviour is therefore needed. An equivalent circuit model for arbitrarily shaped PCB gro...
Ground (GND) and power planes on the PCB are large areas of metal that are connected to either a power supply potential (e.g., VDD) or the common (0 V) connection (commonly referred to as ground). They appear as low-impedance paths for signals and are used to reduce noise in the ...
In other systems, especially high speed ones with large amounts of digital circuitry, it is highly desirable to physically separate sensitive analog components from noisy digital components. It is usually desirable to use separate ground planes for the analog and the digital circuitry. On PCBs which...
Connecting one port of a vector network analyser to the two PCB ‘ground’ planes measured their return loss, S11, as shown in Figure 7, and as a Smith Chart in Figure 8, clearly revealing the suspected resonance to be close to 1.43GHz. ...
> How do you handle these connections that only appear on the PCB and not in > the schematic, and more specifically, stitching ground planes with vias? I'm not sure if I understand your question correctly. But if I do, this may help: Start a track somewhere you have a ground connectio...
I was terrified of using planes in the beginning, because it seemed sooo complicated. But when I decided to try it out, I found that it was really simple :) Now I usually design boards with both ground plane and a positive supply plane. A positive supply plane can be constructed the ex...
