Thermals not updating

Lennie

 I have a dynamic positive plane on the top layer. When I go to global dynamic shape parameters and change the thermals from full contact to diagonal or orthogonal and click ok only the via get updated. How do I get the thru hole and smt thermals to update ?

  • steve

     In Shape - Global Dynamic Params - Thermal Relief Connects tab try reducing the minimum connects option, if it's on the top layer there may not be enough room to add the thermals. By reducing this may connect some of them. You could also maks sure on the Clearances tab that DRC is the set mode.

    That is not the probelm. Currently vias, smt pads and thru hole pads in the design are flooded over(full contact). If I change all of them to diagonal, orthogonal, or change the number of spokes   the vias change correctly and the thru hole and smt pads remain flooded over. It looks like the software has a bug in it ? If you select a shape and change the shape back the thermals then appear correct.

     OK try a Shape - Select Shape or Void then left click the shape then RMB - Parameters. Look at the same Thermal Relied Connects but this time this is for just this shape. If that doesn't help What are the Clearances set to DRC or Thermal/anti. If it's the latter try changing to DRCa dn see if that helps. You could also try a DBDoctor. Also make sure you are on the latest 16.6 hotfix (S024).

     Ok. It looks like there are global thermal parameters, and then local ones per shape.

    Thanks for the help.
