2M27V. Complete list of affected parts is outlined in PCN QSD.
� Scheduled to complete by 30th April 2012 (not including PCN)
� No impact of customer deliveries
1.2 Considerations
� Test Platform Hardware in KLM Probe is identical platform used in OHP
Probe, and verified by tester calibration and dual site Kappa comparative
