Hi Wayne,

You are right to avoid acute angles for electrical/electronic reasons as
well. One of the artifacts at the higher speeds, that are becoming more  common
these days, is signal reflections and emissions as circuit corners  are turned.
Models show this to be the case and it has an intuitive aspect to  it.

If you want/must have really accurate features, pattern plating on  thin
copper is going to provide the quickest solution. If you are going to  volume,
there are some alternatives based on embossing methods that are looking
promising for the future.

Good luck,
Joe
