Relatively new to KiCad. I’m trying to create a footprint for a TO-263-7 Regulator. I’d like to include pads for the heatsink as part of the footprint, but there are some unusual things about this that I’m not sure of.
Below is the footprint opened in editor, followed by 3D view.
Q1. Ground is on pin 4. Can I label the other thermal pads also as pin 4 as I’ve done? Will this match up correctly with a schematic symbol that only has 7 pins?
The large pad to the left in the first picture is the size of the drain pad, but isn’t part of the solder mask layer. I moved it to the left for visibility in this picture only. However, when I place that pad over the top of everything else, it just looks like a giant single pad. No matter what view I check or uncheck, it looks like a standard pad. However, opening within 3D viewer it looks normal.
Q2. Is there a proper way to view solder mask layers within the footprint editor? Or is it not intended to be used like this at all?
Appreciate any insight. Thanks!
