Re: Jumpers and zero-ohm resistors
Given what you are trying to achieve, John, you could create a custom schematic symbol that looks like a wire segment. You could even hide all the text fields. Basically it would just be two back-back

Re: Jumpers and zero-ohm resistors
Thanks, Tony. My need is very simple, to allow one track on a layer to cross another. I can put zero ohm resistors on the schematic, but (inevitably, I suppose) that restricts the routing of the

Re: Jumpers and zero-ohm resistors
If you want to use headers and links, I have schematic symbols for those. Perhaps KiCad even has them in one of its extensive library, I don't know. Alternatively, use zero Ohm resistors, and add a

Re: Jumpers and zero-ohm resistors
Thanks, Jean-Paul, but I want to jump over a track on a 2-layer through-hole board. A zero-ohm resistor works. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

Re: Jumpers and zero-ohm resistors
Hello, ??? Instead of jumper, I offen use so called in French "coffee bean". Just put a drop of solder to make the connection. ??? Regards, Jean-Paul **** Site : f5bu.fr

Re: Jumpers and zero-ohm resistors
Thanks, Robert. I suppose they have to be placed in the schematic exactly where they are needed in the layout, which can make the schematic look very odd. -- This email has been checked for viruses by

Re: Jumpers and zero-ohm resistors
They are normally in the schematic as zero ohm resistors. In the layout they can be whatever you like, eg pukkka zero ohm resistors (wire-ended or surface mount), hand-cut wire links, blobs of solder,

Jumpers and zero-ohm resistors
How are jumpers? included in a board design? Do they appear in the schematic or only in the PCB layout? Are they to be treated as zero-ohm resistors, perhaps? -- OOO - Own Opinions Only Best Wishes

Re: How to print a BOM? [Solved]
To be fair, at age 70, anything post millennial seems pretty recent, and even hurrying occurs at a measured pace, not helped by having to stop for extra coffee to remember where that tube of triacs

Re: How to print a BOM?
That is not pretty recent, that is bordering on ancient. Kicad is now up to version 8, and they bring out a new version with new features each year, along with updates during the year.

Re: OT: PCB suppliers
A few years ago I was using PCB Pool for my hobby boards. They did a great job of finishing the edges of the boards. Basically a clean routed edge on all sides. I then switched to OSH Park because I'm

I don't want to make a big thing of this - as I said it was easy to work around. However, the board *outline* is supposed to have zero thickness - it is just a bounding box not a physical thing. The

Well they are just doing what your Gerbers call for, which sounds like a positive thing to me. What if you /wanted/ the outline on all layers, but found the manufacturer was removing it? I've never

Re: OT: PCB suppliers
That means they panelized it. This is very common and some assemblers will not assemble a board without it. I am guessing your board was bigger than 2 inches? [email protected]> wrote:

The reason why kicad exports xml is to allow the BOM output to be set to whatever you want it to be, including CSV, but it was never user-friendly. Poking around my kicad installation suggests python
