Amkor offers a broad line of LQFP IC packages
designed to provide the same great benefits
as MQFP packaging with a 1.4 mm body
thickness. This allows IC packaging engineers,
component specifiers and systems designers
to solve issues such as increasing board
density, die shrink programs, thin end-product
profile and portability.

LQFPs are particularly suited for light weight,
portable electronics requiring broad perform-
ance characteristics. Such applications are lap-
top PCs, video/audio, telecom, cordless/RF,
data acquisition, office equipment, disc-drives
and communication boards.
