What is a footprint ?

 

First we need to create the footprint for the component before creating the component worth the reduncancia , we must first know what is the trace , the trace is the space that will occupy our component when soldemos on the plate .

So if we have a component which welding if Proteus has no footprint , we have to make .

We search the datasheet of our component such as a web query is as follows .

Looking for the component.

And you give magnifying glass and you see this.

Regulators click on integrated circuits.

We chose the regulator .

Click on technical documentation is PDF .

We see that we have measurements in millimeters and inch , inch operation is recommended for Proteus .
