Rogers Corporation introduced new SYRON 7000 and 7100 high-performance circuit materials, engineered for applications that demand high-temperature stability. The laminates are characterised 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.
The materials are inherently flame retardant and, being halogen-free and compatible with lead-free solder processes, are also environmentally friendly. They are 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 are 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, low-profile electrodeposited copper foil cladding and in several standard panel sizes, including 305 x 457 mm and 610 x 457 mm; other panel sizes and rolls are also available. The laminates are characterised by excellent coefficient of thermal expansion (CTE) and high thermal conductivity for consistent performance at high temperatures.
SYRON 7000 laminates feature a dielectric thickness of 0,0508 mm with thickness tolerance of ±12,5%. 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 0,0508 mm and 0,1016 mm, both thicknesses held to a tolerance of ±12,5%. For the 0,0508 mm 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 0,1016 mm 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.
