It’s standard practice to avoid joining small PCB traces at 90 degrees, but instead to join them at an angle. But does it matter for thick traces?
Above and below are some 0.020″ or 0.024″ traces. Is it really going to matter, with a pad-size trace, what angle the joining trace hits the other one?
Convention would have you do something like the alternative layout below. Either like “A” or like “B.” But, is it really necessary and worth the extra time required to do that?
Part of me really wonders and another part of me says, it shows attention to detail and implies that the entire design was produced with the same care. It’s that elegance in design thing.
The other question I have relates to “B,” in the bottom image. Does it matter which direction the 45 degree trace intersects? Does it matter based on the direction of current flow or does it matter at all?
Which of the three illustrated techniques do you prefer and use?
