Fiducials

Anonymous — Thu, 11 Jan 2018 21:32:05 GMT

I have reviewed the available markers but did not find one that suits my needs. So, would like to design and incorporate my own custom-designed marker/fiducial. I know how to design and use a custom part, but I have never done designed a marker.

The marker I have in mind would be a circle of say 1-mm in diameter which is surrounded by a 3-mm diameter area which is clear of any details (traces, vias, silkscreen, solder mask, etc.). How do I design such marker?

Thanks,

Hi Mo,
There are a few ways you can design fiducial markings, they are like any other library part but with connections.

You can create a device, which links a schematic symbol and a package. That way they can be included in manufacturing or test files (BOM, Pick and Place).

Or you can create a single package. With a package you have to add it from the board only.

You can download my fiducial library and modify them as needed.

Hi Cameron,

do you use Openpnp?

Which size of fiducial works good?

Thanks for the .lbr
