Craig, it seems the minimal conductor spacing conforming 6.3 (table 6-1)
prevents shorts as a result of contamination, delamination, conductive
particles, etching imperfections (crest and overhang). Such
imperfections would faciliate shorts independent of the base material.

Betreff: [TN] IPC-2221 Table 6.1 Conductor Spacing
I was wondering if anyone could provide me with information on
the
research used to determine the conductor spacing requirements of
IPC-2221. More specifically, why is it not material dependent
and
is there a safety factor provided in the spacing determination?
Any help would be greatly appreciated.
Thanks in advance,
