Handling of Parts - Subsequent Testing or Analysis

When removing any part from a board that may be subjected to additional testing or analysis, it is very worthwhile to have the technician spend a bit of extra time removing the part with care, particularly with high pin-count leaded packages.  As we can see from the photographs below, preparing this part for additional testing will be a challenge.

Yes, it was a challenge, but Actel makes the save!!!
