A potential reduction in performance margin from the FR4 laminates being used was initially observed. High-speed bus designs, such as DDR3 & PCIe3 could become problematic due to electrical properties of these HFR-Free materials.

Unfortunately, this transition has been made difficult by concerns of the Thermo-Mechanical and Electrical properties on the HFR-Free laminates. As an example, the critical electrical properties of most HFR-free dielectrics currently on the market make high-speed bus designs such as DDR3 problematic without increasing the cost of the system. The iNEMI HFR-Free Leadership Project was developed to address these industry concerns. This paper shows the project plan and status to date.
