Thanks John,
I had not seen this either previously.
It certainly makes sense [oh 20/20 hindsight], that the 45°hole wall quality
would be different than the standard orthogonal ones.
Big question : Why should this be significantly different for the high-Tg
high-temp phenolic resin materials?-Any explanations, any one?
