In this issue, the editor will bring you about PCB design skills how to determine the background shape according to the size of the circuit board. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

When drawing PCB with Altium Designer, we see that some designs have a black background that is the size of the PCB board, which looks comfortable, while others have a black background on a screen.

Let's take a look at some pictures first. We see that other people's designs look like this:

Although the shape of ↑ is irregular, the background is consistent with the shape of PCB.

Or something like this:

The ↑ PCB is round, and so is the black background.

Or something like this:

The shape of ↑ is regular, but the background is consistent with the shape of PCB.

And your PCB design environment does look like this:

The shape of ↑ PCB is regular, but black is the whole screen.

Or something like this:

↑ black or the whole screen.

How can this situation be changed? The setup method is simple.

1. First draw the shape of your PCB circuit board in Keep-Out Layer, as follows:

two。 In the edit area on the left, switch the navigation bar to "PCB Fileter" (figure 1 below), then type "IsKeepOut" in the white area (figure 2 below), and finally click Apply (figure 3 below).

3. After clicking Apply, you will find that the line of the Keep-out Layer layer is selected, as shown in the following figure:

4. Click Designer → Board Sharp → Define from selected objects, as shown in the following figure.

5. At this time, let's take a look at the background of your PCB, which is consistent with the shape of PCB.

The above is how to determine the background shape according to the size of the circuit board in the PCB design skills shared by the editor. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
