During the reflow process what are you finding most effective for shielding temperature sensitive components?

Ceramic shields, FR-4, sheet metal, machined high temp plastic, cermic non-woven shields

We have had success with both thin folded sheet metal "cans", as well as Aluminum Tape.

In some cases it is just not possible to prevent exposure when in convection reflow, so those parts might have a "hand add" instruction for later mounting.
