RO3035 2-Layer 0.37mm PCB – 10mil Ceramic-Filled PTFE with Immersion Gold for 5G & mmWave

1. Introduction to RO3035 2-Layer 0.37mm PCB

Rogers RO3035 laminates are ceramic-filled, PTFE-based high-frequency circuit materials belonging to the RO3000 series. These materials maintain similar mechanical properties while offering different dielectric constants (Dk), enabling designers to develop multi-layer board designs without compromising on warpage or reliability. RO3035 laminates feature a stable dielectric constant across varying temperatures, providing ideal design solutions for 5G communications, millimeter-wave applications below 6GHz, and massive MIMO systems.
