Welcome to the official website of the
Sauna thermal modeling software package.
The Sauna software package is for the thermal simulation of a
wide variety of electronic components and systems, from
simple heat sinks (heatsinks) to complete boxes with internal
circuit boards (PCB's).
You can use Sauna to create highly detailed models, such as the box
shown above, where there is a detailed trace-by-trace representation
of the PCB. But Sauna is also a great tool for completing a
quick and dirty model. Simple or complex, the choice is yours.
The Sauna program is quite easy to use.
The program includes a large library of standard components and
pad layouts, including standard power packages (TO-247, TO-220, DPAK, D2PAK,
SOT-223, TOLL), dual and quad flat packs (SOIC, MQFP, LQFP, QFN), low
and high power LED packages, as well as user-defined packages.
The program incorporates a full 3D modeler, with specialized tools
for quickly creating boxes, plates with fins, pad patterns and other
geometries common to electronics thermal analysis.
Heat transfer coefficients for both convection and radiation
are calculated automatically. You can calculate temperatures in steady state,
transient or duty cycle modes.
All these powerful features are provided
at a very moderate prices, starting at $995.
Depending on product version, expert technical support is provided
for either 6 months or 12 months. Sauna is an outstanding value.

Sauna V4.55 is now available. Sauna V4.55 includes a series
of enhancements which primarily target circuit board modeling. Key
changes include improved trace and pad drawing in shade mode, library
additions (14 packages), easier modification of copper weight, and
more. For more details, please see
