Your suspisions of rough handling may be the best
analysis.  Here are some things to check:

Start with this.
      Where on the board are the damaged components?
       Are they on/in a location where board flex could
       cause mechanical stress?  Like corners or edges
       of the board.   Then try to deduce  where it is
       occuring on the line.  If you know your process
       well you will find it quickly.
       Experiment with a board.  Flex it and observe the
       resuslts.

Always, examine the damaged components.   Notice
       where the cracks occur.   End caps, middle.

If you are still in doubt call the manufacturer of the
       component.  Ask for the Product Quality Eng.
      They are always willing to discuss component issues,
      especially if it ain't their fault.
