[SI-LIST] Re: Trace Bends

Chai,

Check the message archives.  It has been dealt with quite a bit in the 
past.  I believe that UltraCad undertook some work with Ritchey Lee as 
well.  Below 10's of GHz I believe the consensus is that there is little 
perceptible electrical effects of 90 degree versus 45 degree bends.
