Hi.

 

I have a QFN-10 footprint that I am creating.

The data sheet shows a solder pad under the device (fill), 5 vias and 4
tracks all used for heat sinking.

I placed a copper fill on the PCB component and placed 5 pads and tracks as
shown in the data sheet. The 5 pads have designators that refer to 5 pins in
the schematic component.

The 5 pins all connect to GND. When I place the PCB part and pour a polygon
GND it does not pick up on the fact that the fill, 5 pads and tracks are to
be connected to GND.

Is this the correct approach?
