PTM6880 makes pump-out a thing of the past

Honeywell is proud to introduce PTM6880, an advanced Phase Change Material (PCM) that provides superior reliability, and maintains low thermal impedance (<0.06˚C.cm²/W@ no shim), making it an ideal choice for high-performance integrated circuit (HPC) devices.

Pump-out leads to poor performance of the devices

Pump-out issues with thermal interface materials (TIMs) pose a challenge because they disrupt the efficient transfer of heat between components, potentially leading to overheating and component failure. This phenomenon occurs when the TIM is forced out of the interface gap, creating air voids that act as thermal insulators. This can happen due to thermal expansion and contraction of the interface surfaces, especially with rapid temperature changes.

Addressing these challenges requires an innovative approach to thermal design to ensure efficient cooling in HPCs.

Introducing PTM6880 - a next-generation PCM

The product has been extensively tested and validated for its superior thermal resistance and excellent heat distribution capabilities versus the next best PCM alternative.

Improved thermal resistance against pump out/vertical flow at interfaces: PTM6880 provides a reliable solution by maintaining consistent flatness between the chip and heatsink, even in tight applications needing less than 0.1mm tolerance.

Provides better hotspot distribution: PTM6880 effectively spread heat away from localized high-temperature areas on electronic components to help prevent thermal failure, enhance device performance, and extend the lifespan of electronic devices.

Maintains stable thermal performance required for longer product life applications: With PTM6880, you can achieve efficient heat dissipation, ensuring optimal performance for your chips while minimizing the risks associated with overheating.

Enhances production efficiency: PTM6880 is instrumental in streamlining automated processes while drastically reducing the risk of damage to the bare die. It also decreases the need for rework and repairs, making it the ideal choice for modern high-performance applications.

Based on a novel polymer PCM system, this material exhibits excellent interface wettability during typical operating temperature ranges, resulting in the low surface contact resistance especially for small level range gap applications, including:

AI Servers GPU/CPU, Supercomputing
EV Inverter, onboard charger (OBC), DC/DC converters
Switches, routers, base stations
IGBT Power Module
