Two questions:

1. How much haloing on board edges and around non-plated holes is normally
encountered on polyimide type boards?

2. How much board or non-plated hole edge to conductor spacing is normally
required on polyimide boards to ensure that bridging of a halo does not
exceed 50% of the distance?

Assume 0.062 thick boards for each question.
