All trace angles should be > 135°

Hi Guys,

I saw this constraint in a design:
"All trace angles should be > 135°"

What does it mean?

Could you be more specific? Would it be possible to attach the document or link to the document?

I saw it in AvNet MicroZed design, and it was just that sentence "All trace angles should be > 135°", but did not understand it.

I am not really sure why they have this constraint. Maybe they use a special PCB manufacturer.

I know, that some people point out sharp angles in designs, but from my experience I never had problems to manufacture that kind of PCB. In many designs we do not really have option to choose angles how tracks will be routed - we just need to route where space is and they always manufacture the PCBs with no questions.
