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,
