Technetters, Please direct me to white papers, technical reports, etc, on the reliability of PTHs that exhibit inner separation. The archives have some exchanges from early 2008 and again last month on inner separation. IPC-TR-579 is a document that technetters have referred to from time to time. I'm not acquainted with its contents.

Thanks for any guidance.
