The right way to design a bridge jumper.

[giladk]

A bridge jumper is a component that is technically a 'short circuit' or a 0-Ohm resistor, with an option to mechanically cut the trace with a knife (And then leave open or solder a component instead).

Something like this:

In an attempt to design this in Fusion. I place 2 pads and add a polygon between them.

The problem is that when using this component  I get design errors that needs to be approved every time and routing is very cumbersome.

What would be the correct way to design this?

Tnx

use zero ohm resistors

This can work but this also means that by default there are many more components to assemble which means that the cost for the product will be higher for no reason other than not knowing how to do a proper design.

There's no other way then using zero ohm resistors or approve the design errors.

What you doing here is connecting 2 different nets together and that will always give an error.

Let the error for now what it is and after routing the board completely approve carefully one by one. Ones approved they stay approved.

I have a special component for connecting two nets. It's not exactly the same, but it also causes DRC errors. In my case, there are even four of them.Approving these can be tricky with a large design, as it is easy to overlook actual overlaps. However, I have written a ULP for this purpose. When executed, all overlaps generated by the special package are approved. ULP attached. The ULP is called li-check.ulp. It will only work for you if you also have utilities.ulp in the ULP folder.

Tnx. Although not what I expected, this works.
