Statement of Work & Project Statement


Background

Next-generation 5G communications solutions require ultra-low loss laminate materials and PCBs/substrates for efficient design and manufacturing. However, these materials pose challenges. For example, there is no consistent methodology for measuring transmission loss or Df/Dk, especially for higher frequencies (e.g., >30 GHz). Many different approaches are currently used, requiring different fixtures and test methods, sample preparation, and/or data analysis/extraction. 


Project Focus

The goal of this project is to develop a guideline/best practice for a standardized measurement  and test methodology that can be shared with industry and relevant standards organizations. Initial focus will be to benchmark current available test methods and provide pro/con analysis, identify gaps (if any) for extending test methods to 5G/mmWave frequencies, as well as develop reliable reference standard materials for set-up and calibration.

The project will have two distinct phases:

  • Phase 1: Develop technical guidelines and generate best practices for characterization of ultra-low loss laminate materials in the range of 5-100 GHz

  • Phase 2: Extend the guidelines to PCB/substrate level characterization

iNEMI co-organized a session at EPTC that featured a diverse panel of speakers who outlined the key drivers and applications for 5G such as high-speed computing, smart phones, automotive, networking, IoT etc. The panel-led interactive session discussed many of the design and material challenges that 5G presents, including antenna-in-package (AiP) and beam-forming antenna module array with package-level integration, substrates and PCB fabrication requirements, material characterization, and measurement and test challenges. This session contributed to the development of iNEMI’s initiative on 5G mmWave material characterization and testing.
