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 V5.00 is now available. Sauna V5.00 provides for
circular plates and boards for the first time. This includes
partial circles and pie slices. Also, boards and plates are
allowed to have holes (circular or rectangular), which makes
tubular shapes possible. For more details, please see
Sauna V5.0 New Features and
Sauna V5.00 Release Notes.

Pricing adjustment. There has been a pricing adjustment for all
products. Prices have increased by approximately 5%, which is the
first price increase in several years. The
pricing page has been updated.
