In its design of a multi-function camera vision system, a global
manufacturer of automotive camera systems placed a camera
sensor module with a circuit board near where there is an embedded
chip emitting heat during power cycles. Because the
camera lens is in such close proximity to the PCB, the concern of
silicone contamination heightened the specification of the TIM.
As a result, the thermal material was required to be nonsilicone-based
and to comply with Paint-Wetting Impairment
Substances (PWIS) automotive standards. While there are
non-silicone thermal gap pads available, due to the high-volume
production of the camera assembly, pads were not a feasible
option; only a dispensable material could meet the necessary
throughput requirements.
With the silicone-free requirement from the customer, it was
determined that Therm-A-Gap GEL 25NS met and even exceeded
the customer's requirements, with 2.5 W/m-K thermal
conductivity, and is yellow in color, which can be recognized by
optical cameras on the assembly line.
Furthermore, a finite element analysis (FEA) simulation
was conducted to predict the reacting force of the thermal
material during and after its installation to the targeted location
to ensure it would not cause deformation and/or damage
to the PCB/IC during and after assembly.
For these applications, manufacturers need a dispensable
material that is highly conformable, with a low compression
force and long-term reliability and durability. They may need a
non-silicone-based binder to eliminate factory and assembly
silicone contamination concerns. The thermal interface material
must also be easily dispensed into targeted areas, with no post
curing, to speed the manufacturing process, and offer visibility
to optical cameras. For more information, visit parker.com and

Dispensing Guide for Thermally Conductive Gels, Cure-in-Place
Potting Compounds and Thermal Greases. "
