Eagle: Modifying Silkscreen Layers
When processing Eagle’s BRD files, we use the following layers for silkscreen:
_tsilk, if it exists
_bsilk, if it exists
For including other layers (such as
tValues), you will need to generate gerbers and submit those for your order.
If submitting a BRD file is preferred, you can modify the layer of text belonging to a footprint using the
Smash tool. This lets you modify the text’s Layer property, and move it to one of the above layers.
