    Decal rules do not override default rules!

      Hello,

       

      i have a problem. I want to route some traces under a BGA-Decal (Pitch 0.65mm). Therefore i have set a decal rule (clearance=0.1mm) for this BGA-Package which should override the default rules (clearance=0.15mm). But everytime i do a design verification i get errors which say that my traces under the BGA-Package have a clearance of 0.1mm to the next BGA-Pads but should have at least 0.15mm. I don´t understand why i get those error messages.

       

      Do the decal-rules only effect the pads of the decal but not the traces under the decal area?

       

      Thanks
