How to draw jumpers in Eagle

Community PCB Design

Hello i am new in eagle and i make single side bord but after making bord some line r not converted in to track i.e. unrouted track i want to convet this in track and making jumpers between two line cross over how to make this please help me

Make the board double-sided with the tracks on one side and the jumpers on the other? The software I use allows jumpers on single-sided boards but I doubt if Eagle does.

Another way to do jumpers on a single sided board is to place zero Ohms resistors in the schematic where you need to have a PCB jumper. Then install a wire in the zero Ohm resistor position.

This means going back to the schematic to add the resistor and bring the schematic changes into the PCB. But the PCB DRC will pass without any unrouted tracks.

hi saielectrosystem,

Eagle doesn’t have a setting for single or double sided boards. If you want a single sided board, you only place traces on one side, usually the bottom (as you probably have been doing). For links or jumpers, simply put them on the other side (as leon suggested). You may want to adjust the vias to look like pads. When it comes time for manufacture, there is no need to send the top copper layer.

Another method I have seen is to use zero ohm resistors.

Light Edition Eagle has a lot of functionality at a very good price. :smiley:

EDIT: waltr, it looks like it took me too long to write this response.

Two ways.

  1. As you route the traces, jump up to the top side to cross the places you need. This works great if you’re manually routing. Everywhere you have a red trace, that’s where you’ll solder a wire.

  2. In the part library, go to jumper and look at the J item. There are wire jumpers there 5mm to 30mm spacing. This approach works well if you know where you need your jumpers ahead of time, and you can autoroute it.

Eagle has a library named “Jumpers”, Just pick the jumper you need and your good to go.

Here’s what I did:

  1. Used the component “SJW” from the Jumper library (Eagle 5.11) on my schematic.

  2. Use the command “Layer 101 bJumper” to create a spare layer for 0-ohm jumper connection on my bottom layer.

  3. Added a wires on layer 101 to connect 0OHM jumpers.

  4. Added layer 101 to my CAM job for Gerber file generation on the sol (bottom) layer.

This should work for single and multi-layer PCBs.

In my case I will need to insure my PCB manufacturer (PCB-POOL) knows to combine layer 101 to other “standard” layers when they re-generate the Gerber for my sol (bottom) layer.

Problem solved, DRCs and ERC pass. 8)
