Phase Change Materials

PTM6880

PTM6880 is a Phase Change Pad, Sheet and Paste with a Thermal Impedance of 0.056 (°C cm²/w), Thermal Conductivity of 6 (w/mk) and Specific Gravity of 2.7 (g/cm³)

Overview
PTM6880 makes pump-out a thing of the past

Honeywell is proud to introduce PTM6880, an advanced 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 issues lead 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, engineered to:
  • Improve 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.
  • Provide 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.
  • Maintain 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.
  • Enhance 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
The product has been extensively tested and validated for its superior thermal resistance and excellent heat distribution capabilities.
