Appying Jumpers to a PCB layout using Eagle Cad

I have an automotive application where I need to design a PCB board in Eagle Cad that has jumpers in it to select different modes of operation.

I believe I have found a solution of putting in 2 fake resistors with a drill distance of .1", both attached at a common through hole. But I get a drill distance DRC error. I can accept the error and it will show up as an approved error. But I wasn't sure if the circuit board company will accept this.

My question is will the PCB manufactures accept my approved drill distance error.

The circuit diagram is available in the attached PDF and the circuit picture is presented below.

ZERO Ohm resistors have been used as jumpers for as long as SMT devices have been around.

SMT wouldn't be an issue, but I have a through hole application. The only question is weather or not the PCB manufacture would kick it back because there is a hole spacing error in the file. These are the types of jumpers I am considering.

Thanks John

In my 20 years of experience, board makers will always produce just what you design.

Thanks

There are a lot of "jumper" parts defined in various eagle libraries, although I don't see any with the sort of "corner" configuration you seem to want.

It's not that difficult to add your own parts to a library (copy or modify one of the existing "jumper" definitions), and it would make both the schematic and PCB more readable, as well as eliminating the manufacturing ambiguity.

I found those but I had no luck using them until now. I just changed it to 3 in line jumper instead of trying to overlap 2 two pin jumpers to make that L shaped one and all works well. It even fits better.

Thanks

"L" shaped! Why couldn't I think of that letter (I called it a "T")
