Thermal Clad
Key Benefits Of Thermal Clad
The Bergquist Company is the world leader in the develop-
ment and manufacture of thermally conductive interface mate-
rials.Thermal Clad Insulated Metal Substrate (IMS
oped by Bergquist as a thermal management solution for
today’s higher watt-density surface mount applications where
heat issues are a major concern.
Thermal Clad substrates minimize thermal impedance and
conduct heat more effectively and efficiently than standard
printed wiring boards (PWB's). These substrates are more
mechanically robust than thick-film ceramics and direct bond
copper constructions that are often used in these applications.
Thermal Clad is a cost-effective solution which can eliminate
components, allow for simplified designs, smaller devices and an
overall less complicated production processes. Additional ben-
efits of Thermal Clad include lower operating temperatures,
longer component life and increased durability.
Bergquist Thermal Clad substrates are not limited to use with
metal base layers. In one example, power conversion applica-
tions can enhance their performance by replacing FR-4 with
Thermal Clad dielectrics in multi-layer assemblies. In this appli-
cation, the thickness of the copper circuit layer can be mini-
mized by the high thermal performance of Thermal Clad. For

Applications” section on pages 10-11 of this guide.

Thermal Clad is a complete thermal management system, unlike
traditional technology which uses heat sinks, clips and other
mounting hardware. Thermal Clad enables low-cost production
by eliminating the need for costly manual assembly.
