OPTIPIN™ HEAT SINKS
FOR BALL GRID ARRAY (BGA) APPLICATIONS
Aavid’s heat sinks cool BGA, Super BGA, QFP,
PLCC, and PBGA packaged devices.Typical appli-
cations include set-top boxes, cable modems,
sound and video cards, automotive global posi-
tioning systems(GPS), high resolution printers,
and high-speed network routers.
Aavid’s BGA heat sinks come with a number of
mounting options and in many popular sizes to
fit most applications.
FEATURES:
• The first OptiPin heat sink, the 40 x 40 mm,
cools Intel’s i960
®
RP/RD embedded micro-
processors
• Micro-thin fins provide 20% more cooling per-
formance than conventional cross-cut heat
sinks, making these the optimum cooling solu-
tion for most applications
• The 35 x 35 mm footprint is available in three
different heights: 7.0 mm, 14.0 mm, and 27.9 mm
(see below for part number information).
• All OptiPins come with a standard anodized
finish, and are available with double-sided ther-
mal interface tape particular to metal, ceramic,
or plastic packages, or without tape for epoxy
attachment
NOTE:
1070 tape attaches the OptiPin to ceramic and
metal packages and T410 attaches to plastic packages.
