• 32 to 256 lead counts
• Copper leadframes
• Broad selection of die pad sizes
• Custom leadframe design available
• 1.4 mm body thickness
• Low stress die attach adhesive
• Rapid cure mold compound
• Power enhancement version - PowerQuad
Low Profile Quad Flat
Pack (LQFP) Packages:
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.
Applications:
Amkor’s LQFPs are an ideal IC package for
most IC semiconductor technologies such as
ASIC, DSP, controllers, processors, gate arrays
(FPGA/PLD), SRAMs and PC chip sets.
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.
