I suspect 45 degree bends are due to two main reasons: * Institutional misinformation or cargo cult behavior * Ease of layout based on convention. If you need to match differential trace lengths, 90 degree angles are going to give you pretty big difference length wise, so you need more squiggles to compensate. My point on 90 vs 45 is that some people seem to take the opinion that the 'ideal' trace is some sort of sweeping trace with absolutely no angles, and a 45 degree is a compromise. It's really not. It does not matter. Electrons don't 'bunch up' in corners like some people claim.
