AD350A High Frequency PCB Material Introduction Rogers AD350A laminate is engineered with a PTFE, woven fiberglass, and ceramic-filled specialty material formula, optimized to deliver high thermal conductivity and low coefficient of thermal expansion (CTE) — making it the ideal solution for higher-power designs operating in extreme temperature environments where efficient heat rejection is a top priority. Key Features of Rogers AD350A Tailored for demanding scenarios like wireless communication systems, Rogers AD350A PCB stands out with precise, reliable performance across critical metrics: Well-Controlled Dielectric Constant At 10 GHz and 23°C, the dielectric constant is stabilized at 3.5 ± 0.05. This tight tolerance guarantees consistent signal propagation, minimizes signal loss, and supports reliable, efficient circuit operation. Ultra-Low Loss Tangent Boasting a loss tangent of just 0.003 at 10 GHz, 23°C, and 50% relative humidity, the Rogers laminate achieves exceptional electrical performance with minimal energy loss, directly translating to improved signal integrity and reduced signal distortion. Low Z-Axis Thermal Expansion With a Z-axis CTE of 35 ppm/°C, the board maintains structural integrity even amid significant temperature fluctuations, lowering the risk of mechanical stress or failure. Full Axes Controlled CTE Complementing its low Z-axis expansion, Rogers AD350A Arlon PCB features a CTE of 18 ppm/°C in both X and Y axes (with an additional Z-axis CTE specification of 63 ppm/°C for comprehensive design flexibility). This uniform control of expansion and contraction minimizes stress on components and solder joints, boosting overall product reliability. High Decomposition Temperature With a decomposition temperature (Td) exceeding 500°C, the laminate delivers outstanding thermal stability and resilience. Rogers AD350A circuit board retains its electrical and mechanical properties even under extreme temperatures, ensuring long-term operational reliability. Low Moisture Absorption The moisture absorption rate is as low as 0.1%, protecting the board from humidity-related performance degradation and ensuring consistent functionality in harsh environmental conditions. Low Passive Intermodulation (PIM) AD350A laminate achieves impressively low PIM performance of -159 dBC at 30 mil and -163 dBC at 60 mil, enabling clean, interference-free signal transmission — a critical advantage for high-signal-purity applications like wireless communication systems. Excellent Thermal Conductivity With a thermal conductivity rating of 0.44 W/m-K, Rogers AD350A efficiently dissipates heat generated by high-power components, preventing overheating and supporting stable operation in heat-intensive designs. Larger Panel Sizes Available For enhanced manufacturing efficiency and scalability, Rogers AD350A PCB offers flexible larger panel size options to meet diverse production needs. Core Benefits of AD350A Substrate The advanced material and design of Rogers AD350A PCB translate to tangible, application-centric advantages: Superior Plated Through-Hole (PTH) Adhesion The specialized material ensures robust PTH connections, delivering reliable electrical performance even in the most demanding operating conditions. Effective Heat Dissipation & Management Combined high thermal conductivity and efficient heat-dissipating properties make AD350A PCB a go-to choice for high-power designs, preventing component overheating, optimizing performance, and extending the PCB’s service life. High Consistency Across Batches Rogers AD350A laminate maintains uniform electrical and mechanical performance across different manufacturing runs. This consistency simplifies the design and production process while reducing the risk of performance variations or unexpected failures.
