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.

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.

The Architecture

Solstice Advanced ADAS Thermal Architecture for Next-Generation EV Platforms

For over half a century, Solstice has been a key supplier of semiconductor materials to the worldwide electronics industry. Our product portfolio is designed to enhance the performance and reliability of your products and includes materials for almost every stage of fabrication and packaging applications.

Solstice delivers a tailored solution, engineered specifically for next-generation vehicle-level ADAS compute platforms. This integrated solution combines three robust components to systematically address localized hotspots and enhance the effective dissipation area.

On the Bare Die · TIM1.5

High-Performance Phase Change Material (PTM Series, TIM1.5)

Applied directly on the bare die, Solstice’s PCM offers:

Thin bond line for minimal thermal resistance
Exceptional mechanical compliance
Strong resistance to pump-out and degradation
High reliability under extreme thermal cycling

System Heat Spreader

Customized Heat Spreader

Solstice Heat Spreader is designed to maximize heat spreading across the thermal stack and ensure uniform surface contact.

Optimized material selection: Evaluate high-thermal-conductivity materials aligned with customer requirements for reliability, weight, and coefficient of thermal expansion (CTE).
System-level thermal integration: Co-design the heat spreader as an integral part of the overall cooling architecture — including cold plates, liquid cooling, or air cooling — to minimize total thermal resistance.
Performance-to-weight optimization: Balance heat-spreading efficiency, thickness, and mass to meet customer’s packaging constraints and vehicle efficiency targets.
Manufacturable and scalable design: Enhance compatibility with high-volume automotive manufacturing processes, supporting cost, quality, and supply-chain scalability.
Reliability and platform scalability: Work closely with customers to validate durability under automotive thermal cycling, vibration, and mechanical stress conditions, while enabling reuse across future vehicle platforms.

To the Cold Plate · TIM2

High Conformability Gel TIM2

Placed between the heat spreader and the cold plate, this Solstice gel ensures:

Low contact resistance
Excellent wetting to interfaces
Long-term stability under vibration and load cycling
Room temperature cure or fast cure under heating
Low assembly stress
High thixotropy

Solution Value

Lower junction temperature directly translates to:

Higher sustained compute performance
Longer component lifetime
Reduced risk of thermal throttling
Fewer system-level failures

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