You’ll hear this time and time again if you talk to engineers and manufacturers, don’t use 90-degree trace angles. Why? When you have a bunch of traces that have a sharp, right-angle turn on your board, the outside corner of that 90-degree angle has the likelihood of being etched narrower than your standard trace width. And at its worst, you might get a bunch of 90-degree traces back that aren’t fully etched, resulting in shorts.

As a solution to this problem, try to use 45-degree angle traces. This will produce some beautiful PCB layouts while also making your manufacturer’s life easier by being able to easily etch away all of the copper on your board.

# Avoid using 90-degree trace angles, opt for 45 degrees, with a smooth angle being the best.
