removing bits from tStop

autodeskguest

Hi All,

 

I am laying out a PCB that has a footprint for a module that is a PCB with

side-plated contacts.

 

Underneath the module there are a few vias and I am concerned they might

short with vias on the underside of the PCB module.

 

I thought that I coule edit tStop and remove the stop on the top layer, so

that the vias are completely covered on the top, but open on the bottom.

 

Firstly, is it safe to do this, and secondly, how do I edit the tStop layer.

When I view it, I just see hatched circles where the vias are, but I dont

seem to be able remove them.

 

All hints suggestions and ideas welcome!

 

Thanks,

Chris

    Yes, it's perfectly normal to cover vias with solder mask.  You do this in

    Eagle in the DRC settings if I remember right (I set this so long ago I

    don't remember the details).  Someplace there is a setting for a via size.

    Vias below that size will be covered with solder mask.
