In PCB design skills, how to determine the background shape according to the size of the circuit board, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

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 answer to the question about how to determine the background shape according to the size of the circuit board in PCB design skills is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
