Thermal Greases Though these are messy thermal
interface solution, these have thermal compounds
with typical thermal resistance of Kcm2/W 0.2
1.0.

With silicone or hydrocarbon greases, loaded with
thermally conductive filler materials, this
provides low thermal resistance.

Thermal Pads
These are used to fill air gaps caused by
imperfectly flat or smooth surfaces which should
be in thermal contact. These are pre-cured
thermally conductive elastomeric pads which are
easy to apply.

Due to their thickness, these are low in thermal
resistance of Kcm2/W 1.0 3.0. Typically
require high pressure clamping to achieve
reasonable thermal.
Relatively firm at room temperature, it becomes
soft to fill gaps at higher temperatures.

Phase Change Materials
With thermal resistance of Kcm2/W 0.3 0.7,
these are solid materials that melt between
50-80C.
These are the combination of pad convenience and
grease thermal performance. These avails some
adhesion and are not rework able like greases and
thermal pads.

Thermal Tapes
Thermally conductive tapes are similar to thermal
pads but provide more substantial adhesion across
the interface. Being a Thermal conductive
sealant, its thermal resistance is Kcm2/W 1.0
4.0

Gels
With typical thermal resistance of Kcm2/W 0.4
0.8, these partially cure to reduce mess which is
comparable to grease.

Solder
With traditional heat transfer method, it
requires high heat, electrically conductive but
these days most other options are electrically
insulating. Rework not able and not suitable for
large bond areas. These are available with
thermal resistance of Kcm2/W 0.05
Thermally Conductive Adhesives
www.aok-technologies.com
Through heat dissipation, thermally conductive
adhesives help to protect the electronic
circuitry. Thermosetting polymers provide
substantial long-term strength across the bond
interface, and 2nd to only soldering in ultimate
heat transfer capabilities. With typical thermal
resistance of Kcm2/W 0.15 1.0, it requires a
robust manufacturing process. The adhesives
provide highly advanced solutions capable of
reliable performance in the ever increasing
temperatures of electronic devices and also,
manages heat while solving other application
issues.

The amount of heat transmission through any
combination of materials can be calculated.
Technologically advanced formulations designed to
meet the performance requirements of many high
tech industries includes Telecommunications,
Motor control, Aerospace, Military, Medical,
Electro-optical, Electronic and Robotic.
You can calculate the exact amount of heat loss
while manufacturing the thermal sealant by
understanding the technical terms and the factors
involved in the process.
