Victor,
This question can also be addressed to the Designer Council forum, where you can get invaluable input from PCB designers.

Objet : [TN] PWB/PCB misregistration,
Fellow TechNetters:
I have been asked to collect/gather information on this topic. Therefore, today's topic of discussion is PWB/PCB misregistration, Internal/External. How will this anomaly effect board performance?
What is the worst case scenario? Is there a correlation between misregistration and exothermic event?
Impacts:
Signal Integrity -
High Resistance path -
Electrical spacing violation - IPC2221 Table 6-1, Electrical Conductor Spacing
Hole breakout - IPC-2221 sec 9.1.2.1 & 9.1.2.2
Leakage path -
Laminate Quality - CAF - Dry bundle - Non wet SHORT! -
Victor,
