Questions tagged [ground-plane]

An area of copper on a PCB which is connected to the PCB's ground node in order to provide a return path for current from the various circuits on the board. The ground plane's area is typically made as large as possible (even occupying an entire board layer) in order to minimize its impedance, thus allowing it to conduct high return currents without a significant voltage drop from one part of the board to another. Use with related tags such as "pcb".

Is it necessary to separate ground planes in a PCB if there are different voltages?

I'm designing my first PCB and probably the circuit is a bit complex for my electronics knowledge. So a doubt arised while drawing the layout. The board has got a Microchip MCP73871, an integrated circuit that manages the charge of lithium batteries…

Top layer ground flood on 4 layer board - how should the ground planes be connected?

I have a 4 layer board, with inner layers being power and ground. After laying out the components and completing the tracking I do a top layer flood as an additional ground plane. How should the two ground planes ideally be connected? [There are…

Ground plane under power inductor in DC to DC converters

Is it a good idea to put ground plane (fill the area with copper) under the power inductor in DC to DC converters? I was looking for answers about step down regulators but I would like to know about step up regulators as well.

importance of ground pours

I have been designing boards (2-6 layer). After the complete layout I usually pour a GND in the end all over the board. What are the rules governing ground pours ? In my 1st board I have 2 BLDC motors taking in about 16-20 amps. So having a gnd pour…

Connecting Ground Paths

I am using a stm32f407vgtx to control full bridge drivers which drive a H bridge of 4 N-channel Mosfet. I don't have any idea about grounding. I am thinking of using two separate ground AGND (ground of 5V ) and PGND (power ground 24V) then I will…

Ground Plane for Motors

I'm making my first PCB and would like some advice about ground planes. The pcb it two layer, and all parts are through hole. Bottom layer consists of all the ground pads and everything else is on the top layer. Currently I have a ground plane that…
