Statement of Work & Project Statement
Next-generation 5G/6G solutions require ultra-low loss laminate materials and PCBs/substrates for the efficient design of communications equipment. Development of standard reference materials for precision permittivity characterization metrologies could enable industry to speed development time by reducing the need for iterative design tuning caused by errors in material models.
iNEMI's 5G/mmWave Materials Assessment and Characterization project identified an urgent industry need for reference materials that can be used reliably for low loss material measurements using commercially available tools. The goal of the mmWave Permittivity Reference Material Development project is to develop and characterize suitable reference material(s) for consistent Df/Dk measurement methodologies for characterizing ultra low loss laminate materials. The project team plans to develop a requirements document describing the physical and electrical requirements needed to make a traceable permittivity reference sample useful to industry for calibrating high frequency dielectric characterization spanning 10 GHz to 100 GHz. They will:
Determine specific physical and electrical characteristics that are necessary for a permittivity reference sample to be useful for industry
Examine practical issues that may limit usability of a reference artifact such as physical handling challenges, compatibility with common measurement equipment sets, and artifact surface and uniformity limitations
Study trade-offs between usability and accuracy
Summarize recommendations to enable standards organizations to develop industry-useful, fully traceable reference artifacts for permittivity equipment calibrations spanning to 100 GHz
Evaluate proof-of-concept artifacts developed by standards organizations for usability by multiple laboratories using a variety of tool sets
