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
