Experience Design Freedom with True PCB Polygon Management
To create the best polygon pours on your PCB design you need the best PCB design software; Altium Designer.
TOPICS IN THIS SOLUTION
Use the PCB design tool with the features you need for easy polygon management.
It is rare to design a printed circuit board without some sort of power or ground plane in it anymore. As design requirements become more complex for high speed, RF, rigid-flex PCB circuits, and other design technologies, the need for precisely created planes has become more and more important. The days of simply relying on the CAD system to auto-create a VCC and GND plane on hidden system layers are gone. Instead designers need to create intricate plane geometries to satisfy the needs of signal return paths without creating unintended transmission problems.
Fortunately Altium Designer has this need covered with its polygon pour capabilities. You can use these polygon pours to create the specific size and shape of the power and ground planes that you need for your circuit technology. And while Altium Designer also allows you to create copper placing with dedicated internal planes, the polygon pour can give you an added amount of precision for your copper pours and planes. This will allow you to avoid some of the signal overlap errors that can happen with large dedicated plane layers that should instead use the precise control of a polygon pour plane for the signal return path.
Computer-aided design systems have long had the ability to create both dedicated internal plane layers as well as polygon pours when constructing power and ground planes. Each of these methods has their benefits, and the key is to understand which benefits will help your design the most. It is also very important to understand exactly what the requirements of your power and ground planes are going to be so that you get the maximum amount of signal performance from your PCB layout.
There are a lot of resources available to you in the form of online articles and video tutorials that will give you a better understanding on these subjects. The following will give you a good start:
Understanding What Kind of Plane is Needed for PCB Projects
Not only is the creation of power and ground planes critical to the success of your PCB design, understanding the differences between polygon pours and internal plane layers is also important both for your board and for your overall product.
- Creating power and ground planes is a critical aspect of your PCB design.
- Altium Designer has both polygon pours and dedicated plane layer capabilities for creating power and ground planes.
- There are many benefits that you can realize using a polygon pour instead of an internal plane layer.
Altium Designer gives you may options when setting up a polygon pour
Altium Designer gives you a lot of options in the creation of polygon pours within the PCB editor. You have control over the size and shape of the pour as well as whether it is solid or hatched. You also have control over polygon pour clearances and the size and shape of thermal pads and thermal vias. No matter what style of plane you need, you can create it in Altium Designer.
You Can Create Any Polygon Pour that You Need in Altium Designer
With a variety of file formats available, even dxf files, Altium Designer can make your documentation process easy, no matter the layer of difficulty for your design. Documentation from Altium is available to show you how to create polygon pours in Altium Designer.
- Altium Designer provides you with full control over the creation of your polygon pour.
- Altium Designer also gives you management over all of your polygon pours in one menu.
- Power and ground planes can be created using either a polygon pour or an internal plane layer. Here is a quick tutorial that describes both.
Using the polygon pour, you can create any size power or ground plane for your design
To create the polygon pours that you will need in your PCB layout, Altium Designer provides you will a full suite of tools and functionality that are designed to work together. This unified design environment methodology will allow you to smoothly progress in your design from start to finish.
Starting with the schematic you have control over the schematic symbols and components that you can create or pull from a PCB library which will drive the layout. From the schematic to the layout you will have a vast array of design rules with which to control the clearances and style of the polygon pours that you will be creating. In layout you have control over specific elements such as PCB footprints, trace routing, stitching vias, and even solder mask in order to work in conjunction with your polygon pours. Altium Designer’s high-speed tools also give you the ability to work with the PCB stackup for the best configuration of the board layers that you will use for your polygon pours.
A Powerful and Complete PCB Design System
From the start of your schematic to the final Gerber files and everything between, your PCB design needs the power of Altium Designer.
- See how Altium Designer will allow you to easily configure your schematic with power and ground nets for your polygon pours.
- Your polygon pours will be governed by the design rules that you set up, and Altium Designer gives you a full set of design rules to work with.
- Altium Designer makes working with power and ground layers easy when configuring your design for high-speed layer stackups.
Don’t limit the layer potential of your designs. Your PCB design will need the best possible power plane and ground plane design built into it. To accomplish this you need the most advanced polygon pour functionality in the best PCB design software that you can get; Altium Designer.
