has been a global leader for over 25 years in the
design and manufacturing of innovative thermal management
solutions serving a broad range of markets. Major markets
include telecommunications, computers, industrial controls,
power conversion, transportation, medical, alternative energy and
aerospace.
R-Theta’s powerful software “R-Tools” provides on-line thermal
modeling of heat sinks for semiconductors in natural or forced
convection for air cooled, as well as, liquid-cooled cold plates.
The interface is friendly, with only minimal parameters needed to
be specified. Users can register free on-line for R-Tools on the R-
Theta web site

.
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
