How to make a jumper between the pads of two different plug-ins in PCB? As shown in the figure, how to set a jumper between J1 and J2?

First, place a 2-pin socket where the jumper cap needs to be placed in the schematic diagram, add a package, and pay attention to the package size consistent with the jumper cap used, and update it to the PCB diagram.

Yeah, I see. Thank you! Another question: J1 and J2 in the above figure need to be fixed with screws and connected through copper bars, not jumper caps. Similarly, after adding a 2-core socket to the schematic diagram, it is necessary to overlap the two pads of the 2-core socket with the two pads of J1 and J2 in the PCB. Is this done? In this case, won’t an alarm be generated because the components are too close together?

J1 and J2 need to be fixed with screws. This kind of connection needs to carry current, so there is no need to make a 2-core socket on the schematic diagram,

Directly lead out some routing holes at these two pads, and use the pad properties to process the surface connection of the holes, or use flower pads, and screws with gaskets to fix them.

There are other components and traces on the board between J1 and J2. The current between J1 and J2 only runs on the copper bar, so it is impossible to use copper foil or traces to connect J1 and J2 on the board. It can only be in the form of a jumper.

It is OK to connect copper strips. Some places call it copper foil. Pay attention to whether the heat generated by large current will cause deformation of the PCB. The copper strips must be firmly fixed, otherwise there are potential hidden dangers.

Yes, thank you for reminding me. Back to the way to deal with the jumper here, it must be to add a 2-core socket to the schematic diagram, and then overlap the two pads of the 2-core socket with the two pads of J1 and J2 in the PCB. Is this the way to deal with it?

Whether to use jumpers or copper bars is not a problem in software drawing. The method to use depends on the current size of the path, etc. For example, within the current range allowed by the jumper, the jumper is still firm and easy to assemble and standardize.

Yes, I understand. Thank you very much!
