Gentlemen,
the right angle bends are not OK for PCB manufacturing, acting as acid traps. Harder to clean, they might affect the long term reliability.

Subject: [DC] Who's afraid of the big, bad bend?
Howard Johnson strongly believes right angles are not a problem. He
says right angles just begin to have an effect at speeds exceeding 10
Gbps. He categorically dismisses claims about the electrons have
trouble banging around the corner. He also dismisses the idea the
corners act as antennas.
Check out his article on this issue:
