Development and characterization of graphene-enhance material for cooling of large power electronics

Purpose and goal: The project is a SME-project within the frames of the Vinnova Competence center 2D-Tech.

A power cycling test is at the beginning of a value chain of electronics product qualification.This project aims to develop a novel power cycling test methodology on graphene-enhanced thermal interface materials (TIM) and characterization for electronis testing up to 800-1200 watts Thermal Dissipated Power. This value is typically found in the coming AI electronics.

A standardized method will provide reliable and comparative data to shorten the product qualification time to further speed up the development of this new graphene-enhanced thermal interface materials (TIM). Expected results and effects:

The graphene-enhanced TIM will be optimized to meet the requirements of the power cycling test. Meanwhile, a set up that mimics the power cycling of the real electronics during operation will be designed, manufactured, and characterized. These results may enable the graphene- enhanced TIMs to be accepted and widely used in large scale in advanced electronics such as in AI system, which may make Smart High Tech the world leading thermal interface materials company.

The new set-up can potentially to be standardized to electronics/semiconductor companies to shorten the evaluation time. Approach and implementation:

Firstly, the specification data for the graphene-enhanced TIM and test equipments will be investigated and determined according to the market requirements. Then the TIM will be optimized for qualification of the power cycling test. At the same time the test equipment will be designed and fabricated accordingly.

Afterwards, the power cycling test on the TIM will be carried out and the methods will be standarized. Meanwhile, the thermal and mechanical performance of the graphene-enhanced TIM will be also characterized.The results will be published in conference and workshops.
