Electronic – Altium silk screen carried over into copper layer

altiumsilkscreen

My PCB vendor informed me today that a silk screen feature that is carried over into the copper layers, lands on traces and causes shorts (yellow box on the right).

The yellow box is a connector and I got the Altium library from Samtec directly, I just wonder if it is a real problem, if it is how do I remove the silk screen.

Your problem might be in your output job Gerber configuration and your (and Samtec's) selection of mechanical layer.

If you drew the board outline on a particular mechanical layer and the Samtec library happened to use that same mechanical layer for the (non-overlay) outline of the connector you could have a problem iff you selected "Add to All Plots" for that layer in order to have the outline shown on each layer. Just because it's shown on the overlay layer does not mean it is not duplicated on another layer (and it may show up in Altium as overlay color or mechanical layer color depending on the which layer is on top at the moment).

In such a case you can move your outline to another layer and regenerate the Gerbers with the "Add to All Plots" tick removed from the previous layer and turned on for the new layer.

Alway inspect your Gerber files in Camtastic or some other Gerber viewing program, you can save a lot of time and irritation.
