Non-rounded track endcaps (connecting wide tracks to multiple narrow pins)

Layout
1

So I’ve got a current measuring shunt IC in a 24 pin QSOP package. It uses multiple pins for the current sense lines, and I was wondering if anyone had thoughts about the best way to connect that up to a wide track. See the image below to get a sense at what I’m looking at. Is there a way to specify that a particular track has a non-round endcap? Or do people just do a filled zone?

You left out quite a bit of information.
What is the IC you are using?
What does the DataSheet for those pins state?
What voltage and current is expected through the shunt?

I can not give an answer with the information currently presented.

I see nothing wrong with the filled zone idea. Depending on current requirements perhaps just do smaller traces to the pins? I believe you can change sizes mid trace.

Just to clarify a bit, I’m looking for general advice about the best way to use PcbNew, and what people have done in similar situations in the past. Possibly they just use filled zones, even though that seems a little bit clunky.

I probably should have posted this under the “software” category, instead of the “layout” category.

In fact wide traces with the rounded endcap seems cumbersome, even for other situations (where you are not trying to connect to multiple pins). Maybe someone has a little writeup describing how they effectively used wide tracks in the past?

I wouldn’t be surprised if there was an option to set the end cap style on a per track basis, but I haven’t had much luck in my searches so far. But there could be different terminology I’m not familiar with.

Thanks for the confirmation. If that’s the easiest and best supported method, that’s what I’ll do. Thanks!
