Silk screen on an exposed pad with no solder mask
« on: November 06, 2014, 05:02:20 pm »
Just realised this should be in here:

Hi,

Does anyone know if the silk screen is applied after the PCB is solder levelled/plated so that a silk screen can be applied to what would normally be a pad?

You obviously would get a DRC error if you put text on a pad but could a PCB be produced this way intentionally.  It's a pad that is not intended to be soldered.

PCB house will remove any silkscreen over exposed copper. If you ask pCB service to to this, might be possible. However adhesion might be not good.

Usually it's an error but apparently some of them will print silkscreen over pads if you really want them to:
