4 (PQ4) is the same Amkor
patented, advanced IC packaging technology used
in MQFP PQ4s but applied to Low Profile 1.4 mm
QFPs (LQFP). Improved power dissipation is
achieved by using an exposed copper heatslug. This
large copper heat slug extracts generated heat from
the leadframe to which the IC is attached. Thermal
resistance improvements of approximately 30%
(over a standard LQFP) can be realized with this IC
package without the use of any external cooling
aids! In addition, the patented LQFP PQ4 heatsink
has integrated mechanical 鈥渓ocking鈥?features to
ensure total package integrity and eliminates mois-
ture penetration. The end result is a high-power,
high-speed IC package with the properties to enable
new, smaller, denser, portable electronic products
and emerging end applications to operate with
more features and greater reliability.
Applications:
Major semiconductor manufacturers and packaging
engineers have chosen LQFP PQ4 as the IC package of
choice for power microprocessors, controllers, DSPs, high
speed logic/FPGAs, PLDs, ASICs and other advanced
technologies. System designers and OEM product
developers find the LQFP PQ4 solves power, thermal
and speed concerns while supporting system constraints
(standard package outlines, cost, SMT capability,
product availability, technical support) in uses such as:
laptops, notebooks, telecom, cordless/wireless, high-
end audio/video, CPU/GUI board systems and many
other small form-factor applications.
