Driving the Future of ADAS through High-Performance Thermal Solutions

Advanced Driver-Assistance Systems (ADAS) are transforming modern mobility – powering autonomous features, real-time perception, safety algorithms, and high-speed computing that must operate flawlessly in all environments. But as automakers push toward higher compute density and centralized architectures, the thermal burden on these AI processors has never been greater.

Heat has become one of the most critical constraints in next-generation ADAS design. That's exactly where Solstice Advanced Materials delivers a next-generation solution. From chip to enclosure, we turn heat into a controlled pathway, not a risk.

Today's ADAS Electronic Control Units (ECUs) run extremely hot due to heavy and continuous workloads. Modern vehicle architectures shift from many distributed ECUs to centralized computing, resulting in high computing density in confined spaces. Unlike traditional ECUs that dissipated only a few watts, today's systems operate at data-center-like power densities but are designed to be as compact and efficient as possible. Heat transfer is no longer driven by air — it is driven by material pathways. It creates a growing need for better, more effective ways to move heat out of these systems and keep them running safely and reliably.

Thermal management in ADAS is a real challenge as they are subjected to rapid temperature swings, constant vibration, and must meet zero-defect automotive reliability expectations.

This harsh environment puts tremendous stress on conventional thermal interface materials. Without a robust thermal strategy, systems can experience rising junction temperatures, degraded compute performance, early aging, or even catastrophic failures.

In modern ADAS architecture, thermal management is a critical design priority, not an afterthought. Optimizing ADAS thermal performance requires early, physics-driven engineering decisions. By seamlessly integrating thermal interface materials and heat spreaders at the system level, Solstice positions itself as a strategic thermal solutions partner – enabling clients to achieve lower junction temperatures and uphold the highest standards of automotive reliability and manufacturability.

To overcome these challenges, Solstice partnered from the silicon level with a leading automotive AI computing customer to co-engineer a complete thermal architecture tailored for next-generation full vehicle-level ADAS systems.

The integrated solution combines three robust components to systematically address localized hotspots and enhance the effective dissipation area.

Combined, these materials create a multi-layer, highly optimized thermal pathway engineered for ADAS compute loads.

Solstice validated this integrated solution through its in-house Thermal Test Vehicle, where the Solstice PCM delivered a significant reduction in junction temperature compared to stacks without PCM.

Solstice's portfolio is built for the toughest automotive conditions: extreme heat, rapid cycling, high humidity, vibration, shock, and chemical exposure. The flagship Solstice PTM 7900 material passes every major AEC-Q qualification category, including thermal shock, humidity, storage stability, mechanical stress, and corrosive gas exposure.

This makes Solstice's materials ideal for:

• Autonomous domain controllers
• Centralized vehicle compute
• High-power ADAS processors
• In-cabin and under-hood digital control units

With ADAS platforms expected to operate flawlessly for 10–15 years, Solstice ensures components stay cool, stable, and reliable over the full vehicle lifetime.

Solstice offers one of the industry's most comprehensive ranges of thermal materials – covering thin bond line PCMs, gel TIMs, gap pads, and hybrid fillers tailored for diverse ADAS and EV power densities.
