When reading through the review comments of a PCB, there was one which raised some questions for me: "Aim to route tracks out of pad centres and in line with the pad, not exiting at an angle."
I usually try to route from the centre of pads, as most PCB tools snap the track in, so it can be usefully tied in when moving things around. But I'm not sure how important that is for EMC, PCB creation, manufacturing or reliability. Does the trace out of the pad cause a thermal path to make the solder pull away enough during soldering to potentially cause issues?
The second part of the comment, the not existing at an angle is also strange. Why would an angle matter? I can't see how that would matter, and many connections are round (BGAs, and through hole pins for instance). Is there something I don't know, or is this historic?
