PCB track goes to two areas. How do you prefer to split it?
« on: January 12, 2015, 10:15:48 pm »
I have to split a low speed signal track out to two places. Routing through a pad won't work here. Either way, it just doesn't look "right" to me. What do others do when presented with this problem?

Option 1. "Y" bend
Option 2. Fork out 90 degrees
Option 3. Via and fork out
Option 4. Something else?

What..?

Oh, the trace on the right..?  You didn't make it obvious what you were talking about... the screenshot isn't cropped around the subject, and the cursor and crosshairs aren't anywhere near it either...

1. is undesirable because of acute angle.
2. is fine.
3. is also fine but wastes two vias and penetrates the ground pour.

You can augment 2 by adding a triangle or diamond or fillet sort of thing (gussets or teardrops), but this isn't usually important.  Sometimes, manufacturers will request that they add such features, though usually around THT pads (where the drill can miss and cut the annular ring apart from the trace).

If there are no extra requirements, then option 2, of course
