How are polygons used in printed circuit board design?

Polygons are often used in PCB design and they are often referred to as polygon or copper pours. These are the areas of the PCB which are filled with copper over the existing components. If you are defining a polygon then you should know that it can only be done on signal layers which are then rendered in the position.

When does a PCB trace carry more current?

When a trace is not able to carry the needed current in a single layer, the trace can be routed on multiple layers and be subjected to via stitching linking the layers. This will increase the current-carrying capacity in cases where the trace thickness is the same on both layers. What is a PCB trace width calculator?

Can a polygon be defined on a PCB?

These are the areas of the PCB which are filled with copper over the existing components. If you are defining a polygon then you should know that it can only be done on signal layers which are then rendered in the position.

What’s the difference between copper and high current PCB?

Higher copper thicknesses can be 35 and 50microns. The higher the copper thickness, the less wide your trace has to be to carry the same current. More increased copper thickness does come at an additional cost but can help save space on your boards since, with higher viscosity, the trace width required is much less.

How to make polygon pours in PCB editor?

Once open, go to the left side of the menu and select “PCB Editor > Defaults”. From there select “Polygon” and the preferences menu will now look similar to the picture below. Notice that you can set values for different design layers and default naming structures.

How are polygon pours used in copper wiring?

A Polygon Pour (Place » Polygon Pour) placed on a signal layer creates a polygonal (multi-sided) area of copper, which can either be solid or hatched. As they are poured, Polygons automatically allow for clearances around electrical objects belonging to a different net, connect to objects of the same net, and fill irregularly shaped areas.
