Thermal area for single pin net

Question asked by sdonaldson on Jul 8, 2016

I'm using PADS 9.5.  I have a DDPAK with an isolated tab that needs some copper on the board for a heat sink.  This is a single pin net, so it's not named/listed in the netlist to assign a copper plane area.


I currently have it as a flooded plane area, then drew my own thermals from the pad to connect to the plane.


Another option would be to have a "heatsink" component on the schematic and make the footprint a test point or dot or something.  This requires the schematic symbol to be updated to add the tab pin.


Are there any better options?
