I avoid right angle turns on the theory that the sharp exterior corner increases the risk of the copper foil peeling away from the substrate.

- iamkroot 7y agoYeah this is the only explanation I've ever heard. It's the same reason why you avoid acute angles in the design.
- russdill 7y agoNearly every single pcb designer uses square pads with 90° corners.
- coryrc 7y agoPads are much longer than the width across the smallest corner, so if it gets rounded a little, there's no problem. But a 90° corner for the thinnest trace is vulnerable to being etched from all sides and getting too thin.
