DESCRIPTION
STATS ChipPAC’s Stacked Die QFP offering includes LQFP-
SD, LQFP-ep-SD and TQFP-ep-SD. LQFP-SD is a stacked die
low profile QFP. LQFP-ep-SD is an exposed pad version that
provides enhanced thermal performance. TQFP-ep-SD is a
thin profile exposed pad version with enhanced thermal
performance. STATS ChipPAC’s chip stacking technology
allows the integration of multiple ICs within a single
package to improve package performance and functionality
while reducing overall package size and cost. The die to die
wire bonding capability enables device/signal integration
to improve electrical performance and reduce overall
package I/O requirements. STATS ChipPAC’s Stacked Die
QFPs with nominal package thickness of 1.40mm and
1.00mm are suitable for a variety of product applications.
Stacked Die QFP packages are currently available in LQFP,
LQFP-ep and TQFP-ep configurations, and are offered in
standard and green/lead-free bill of materials.
APPLICATIONS
Suitable for a variety of applications including memory
integration (ASIC or Logic), chipset integration (Analog/
Digital), mixed technologies integration (Baseband/RF),
handheld products (Cellular Phones, Pagers, MP3 Players,
GPS), consumer electronics (Internet applications, Digital
Cameras/Camcorders), computers (Network PCs), and PC
peripherals (Disk Drivers, CD-R/RW, DVD Drivers).
