How to draw a plum blossom pad in AD? The plum blossom pad network is independent and does not belong to any network [Copy link]

 

As shown in Figure 1, this is a USB mounting hole. I want to make this mounting hole into a plum blossom solder pad, but it does not need to be grounded. I want to make it into an independent exposed copper sheet (as shown in Figure 2). However, after the entire board was paved with copper, a short circuit error was reported at the plum blossom hole. Does anyone know how to eliminate this short circuit error?

Make the plum blossom pad and the surrounding pad into a package

Or make it a network name in the schematic diagram

There is no such pin in the schematic diagram, so it is impossible to set up a network. This means that the plum blossom pad and the surrounding pads are made into a package, but an error is still reported. However, if there is no network between the plum blossom pad and the surrounding pads, there will be no short circuit error. Is it that the rules believe that no net networks are different networks, so the plum blossom pad and the surrounding pads are considered to be short-circuited?

In the case of normal layout, add vias. If the via and the pad are in contact, the via should be automatically assigned the corresponding net.

Why does it report a short circuit error when I draw a line on a pad without a network?

Normally, yes, if the pad has a network, the via in contact with it will be assigned the same network, but if the pad is no net, the via in contact with it will report a short circuit error. If you don't believe it, you can try it yourself. I can't upload screenshots here.

There is an extra pin in the schematic diagram, the same network name, and overlapping placement in the PCB diagram

Make a plum blossom package pad in advance

No net will not appear

As for the rules, it can be allowed or not to allow short circuits, it seems to be design--rules--electrical--short-circuit

Let me put it this way, why does the no net pad report a short circuit error when routing outward? Solving this problem will solve my problem.

Take a screenshot of the wiring where the alarm and error are reported

_earth

Some people say that the no net network does not allow routing. I just want to expose the copper of that wire. Is there any way to do it?

As mentioned on the 8th floor, short circuits can be allowed or not. In the rules, design--rules--electrical--short-circuit setting

It's not allowed here

For pads without a network, the allowed and disallowed conditions are as follows
