Standard products offered in this catalog are Heat Sinks for board
level IC’s, Surface Mount and Thru-Hole Discrete semiconductor
packages, Extruded heat sinks, Fabfin and Aluminum Extrusion pro-
files. Thermal interface materials include silicone and non-silicone
Thermal Compounds, Sil-Pads and Adhesive tapes.
R-theta also offers a complete line of high performance patented,
aluminum alloy heat sinks without the use of glue and are available
through R-Theta’s extensive line. The company has developed leading
edge heat sink technology that eliminates volumetric constraints of
one-piece extrusions. By mechanically swaging the parts together
there is no deterioration in perform-
ance compared to a solid block of
aluminum. R-Theta heat sinks mean
greater thermal design flexibility by
offering the same co-efficient of
thermal expansion for the entire
heat sink. R-Theta heat sinks allow
you to maximize heat cooling by
pushing the thermal envelope for
greater productivity.

FABFIN Heat Sinks for IGBT and High Power Devices
www.r-theta.com
FABFIN Standards - Various Widths Available in Serrated or Corrugated Fins
FFC SERIES WITH SIDE FASTENED LEGS AND FAN BRACKET
The R-Theta®range of stan-
dard Fabfin®forced convec-
tion cooled heat sinks (FFC
series) was developed to
incorporate standard 119mm
square axial fans. The fin
spacing of 8.51 mm was
selected to provide a 20:1
ratio, the practical heat trans-
fer limit for cooling Power
Semiconductors in typical
ambient conditions. The stan-
dard FFC series shown will
accept 1, 2, 3 or 4 (not
shown) fans. Available in
many finishes.
The serrated fin thickness of
2.4mm provides near opti-
mum performance when
using industry standard axial
fans. If some level of per-
formance de-rating is accept-
able (approximately 20%)
then we recommend that
corrugated fins be used.
These have a thickness of
1.5 mm and are designated
by ordering the ‘AC’ part
numbers. The use of corru-
gated fins provides a weight
savings of approximately
15% and will increase sur-
face area by 7% compared
with a straight fin of the
same height.
The push/pull (PP) option is
common for applications
where fan redundancy is
important. We recommend
the use of ball bearing fan(s),
specifically for the “pull” end,
in order to maximize the fan
life due to the elevated oper-
ating temperatures. The
additional weight of the fan
can be offset by using the
corrugated fins, if applicable.
The adjacent graphs provide
a performance guide for heat
generating devices ranging in
size from point source to
60% coverage.

Polar Thermally Conductive Adhesive Tapes
Ceramic or metal packages
T405 thermal tape consists of a high bond strength, pressure-sensitive acrylic adhesive, loaded with aluminum oxide and coated onto
a 0.050 mm (0.002 inch) aluminum foil carrier. The aluminum foil provides added thermal conductivity for applications where electri-
cal isolation is not required.
T412 thermal tape consists of a high bond strength, pressure-sensitive acrylic adhesive, loaded with titanium diboride and applied to
an expanded aluminum carrier. The combination of filler, expanded metal and embossed surface enhances both tape conformability and
thermal performance.
Plastic packages
T410 tape consists of a high bond strength, pressure sensitive acrylic adhesive loaded with aluminum oxide and coated onto a 0.05 mm
(0.002 inch) aluminum foil carrier. The other side of the foil carrier has a silicone pressure sensitive adhesive which provides excellent
adhesion to silicone-contaminated plastics and other low energy surfaces.
T411 tape consists of a high bond strength pressure-sensitive adhesive with an expanded aluminum mesh carrier layer. The mesh carrier
allows the tape to conform to curved surfaces of plastic molded IC packages, providing a high adhesive strength attachment for heat
sinks. The high performance silicone PSA allows adhesion to silicone-contaminated plastics and other low energy surfaces.

Extruded Aluminum Heat Sink Profiles
Note: There are many more sizes and styles available. Consult the website for a complete listing.
EXTRUSION CHARACTERISTICS TABLE
THE MULTI-PURPOSE ALLOY - 6063 -T5
6063 is a multi-purpose alloy that is most widely used for heat sinks and architectural hardware because it is
extrudable into complex shapes and lends itself to anodized coating. The T5 temper provides sufficient hardness
for ease of machinability. 6063-T5 is the aluminum extrusion most commonly used by R-Theta.
