Taconic RF-30A PCB Substrates Introduction Taconic RF-30A is a organic-ceramic filled laminate in Taconic’s family of RF substrates. It is based on woven glass reinforcement. RF-30A laminate is a result of Taconic’s expertise in both ceramic filler and PTFE coating technology. Taconic RF-30A PCB material is the best choice for low cost, high volume commercial microwave and radio frequency applications. Core Benefits Improved PIMD Performance Taconic RF-30A high frequency laminate delivers exceptional Passive Intermodulation Distortion (PIMD) levels, a critical advantage for multi-frequency communication systems. When processed with state-of-the-art parameters and paired with CL1/CL1 cladding, it exceeds industry PIM requirements, achieving -153 dBc across key frequency bands (880–960 MHz, 1710–1880 MHz, 1920–2170 MHz) at 20 W power. Its stable PIM performance remains consistent even in microstrip transmission line applications, with minimal impact from external factors—whether with or without plated through-hole (PTH) structures. Enhanced PTH Quality & Multilayer Fabrication Ease Optimized with ceramic additives, RF-30A laminate features a low Z-axis coefficient of thermal expansion (CTE). This design significantly improves PTH reliability and streamlines the fabrication of multilayer circuits, reducing production complexities and boosting yield rates for high-volume manufacturing. Stable Mechanical Properties The substrate boasts low CTE values, superior dimensional stability, and high rigidity, ensuring RF components made with RF-30A are less susceptible to external environmental factors. This stability translates to consistent performance across the product lifecycle, even under fluctuating operating conditions. Stable Performance at High Frequencies As a low-loss dielectric substrate paired with low-profile copper foil, RF-30A maintains stable electrical properties across broadband frequency ranges. It minimizes insertion loss while supporting reliable signal transmission, making it ideal for high-frequency microwave and RF use cases. High Temperature Stability & Low Moisture Absorption RF-30A laminate exhibits excellent high temperature resistance, adapting to harsh operating environments. Its ultra-low moisture absorption rate, combined with a stable loss tangent, minimizes phase shift caused by temperature or humidity variations, ensuring signal integrity in diverse application scenarios. Excellent Peel Strength With outstanding peel strength for ½-ounce and 1-ounce reverse-treated (RT) copper foil, RF-30A is well-suited for applications requiring rework or repeated reflow processes. This feature enhances manufacturing flexibility and reduces the risk of substrate damage during production adjustments. Outstanding Price-to-Performance Ratio Balancing high-end performance with cost efficiency, RF-30A stands out as a cost-effective solution for high-volume commercial applications, delivering premium substrate capabilities without excessive price premiums.
