Patience, good eyesight, a steady hand and a narrow soldering pencil. 
Removal isn't quite as tricky as replacement with the radial caps.   The one 
thing to keep in mind is that the SMD pads cannot take any lateral stress 
with leaded components or breakage will surely result.

During installation of the new caps, they must be positioned against the 
headphone jack while heating/soldering with a pencil.  Then, a hot glue gun 
is used to bond the caps against the headphone jack. The caps cannot be 
"straightened" after heating or the pads will lift.
