[SI-LIST] Re: 90 degree bend

There's a good article on that topic here: http://www.ultracad.com/90deg.pd=
f=20

The gist of it is that the negative effects of 90 degree corners are real, =
but are extremely small and are dwarfed by things like vias and pads. The =
most credible justification is that mitered corners reduce the length of =
the trace, and that is much more likely to make a real difference than is =
the angle of the bends. So mitering is still a good idea, but it's a bit =
silly to get religious about it unless you're doing something extraordinari=
ly critical. Anyway, read the article. The author has much more expertise =
than I do.
