Hi Siegmund!

Go to: http://www.national.com/packaging/llp/

and you'll find Application Notes AN-1187 which is all about LLP's. Designing 
them in assemblies, reflow profiles, and rework procedures. There's even a 
RealMedia video there that is showing the steps to use when reworking them. 
They're using a OK Systems (now Metcal) BGA 3000 rework system.

According to National Semiconductor, LLP's are perfect for a wide variety of 
applications. Such as:

Cell Phones 
GPS Receivers   
Pagers  
PDA’s   
Personal stereo / CD    
Hard disk drives    
Hand held portable devices  
Toys    
Notebooks
