Rogers Introduces High Temperature Thermoplastic Circuit Materials
Rogers Corp. announced its new SYRON® 7000 and 7100 high-performance circuit materials, engineered for applications that demand outstanding high-temperature stability. These innovative thermoplastic circuit laminates are characterized by a considerably higher melt temperature than PTFE circuit materials, with an estimated Underwriters’ Laboratory (UL) relative thermal index (RTI) of greater than 210°C (410°F). They are also inherently flame retardant. Environmentally friendly SYRON thermoplastic circuit materials are halogen-free and compatible with lead-free solder processes. They are also resistant to the solvents and reagents commonly used in printed-circuit-board processing, and can operate in harsh chemical environments.
SYRON laminates are designed for environments with a high maximum operating temperature and ideal for circuits operating through microwave frequencies. They are suitable for flex-to-install applications, lightweight feed manifolds, automotive sensors, and in electronics for oil and gas exploration. The SYRON 7000 and SYRON 7100 materials differ somewhat in their electrical characteristics, although both are available with ½-oz. very-low-profile electrodeposited copper foil cladding and in several standard panel sizes, including 12 x 18 in. (305 x 457 mm) and 24 x 18 in. (610 x 457 mm). In addition to the standard panel sizes, other panel sizes and rolls are available.
SYRON 7000 laminates feature a dielectric thickness of 0.002 in. (0.0508 mm) with thickness tolerance of ± 12.5 percent. They exhibit a maximum z-axis dielectric constant of 3.4 at 10 GHz, with maximum z-axis dissipation factor of 0.0045 at 10 GHz. SYRON 7100 circuit materials are offered with dielectric thicknesses of 0.002 in. (0.0508 mm) and 0.004 in. (0.1016 mm), both thicknesses held to a tolerance of ± 12.5 percent. For the 0.002-in.-thick SYRON 7100 material, the maximum z-axis dielectric constant is 3.61 and the maximum z-axis dissipation factor is 0.006, both measured at 10 GHz. For the 0.004-in.-thick SYRON 7100 laminate, the maximum z-axis dielectric constant is 3.39 and the maximum z-axis dissipation factor is 0.005, also at 10 GHz.
SYRON 7000 and SYRON 7100 laminates are designed for reliable electrical and mechanical performance in harsh, high-temperature and chemical environments. Both materials are characterized by excellent coefficient of thermal expansion (CTE) and high thermal conductivity for consistent performance at high temperatures.
