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, ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
