Thermal conductivity testing for thermal interface materials (TIM)

Get actionable insights into the real-world performance of your thermal interface materials with our enhanced conductivity testing. Built on ASTM D5470 principles and optimized for practical adaptability, our testing services empower better design decisions through precise, application-specific thermal data.

Based on ASTM D5470, adapted for practical innovation

While our method draws directly from the ASTM D5470 standard, our custom-built TIM test station does not claim full compliance. Instead, we’ve engineered it for:

  • Wider adaptability to varied material formats
  • Realistic loading conditions and application-specific configurations
  • Maintaining core measurement principles (heat flow, temp gradient, clamping pressure)

This approach allows us to generate reliable, repeatable data that’s directly relevant to your use case, while still rooted in industry-standard methodology.

Our custom TIM test station

Designed and built in-house for reproducible thermal testing across a range of material types:

  • Controlled thermal gradient & heat flux measurement
  • Custom clamping system for consistent pressure application
  • Adjustable temperature range for environmental simulation
  • Compatible with pastes, pads, putty, phase change materials, and more

Industries and applications

  • TIM developers seeking fast, comparative validation
  • System integrators needing thermal performance data
  • QA teams verifying thermal consistency across batches
  • Research teams adapting materials for advanced cooling solutions

What we test for

  • Heat transfer from the heating side to the cooling side
  • Temperature-dependence behavior curves
  • Details on pressure, test conditions, and stack-up
  • Optional benchmarking to customer-supplied materials

We treat your IP like our own

  • Ship your materials samples securely to our lab.
  • All testing and data are handled under strict confidentiality and IP protection protocols.

Let’s test smarter

You don’t need full ASTM certification to get valuable, decision-making data. Let’s test your TIMs with speed, flexibility, and the precision that matters.
