Chandler, Arizona - Rogers Corporation will display some of its high-performance materials for electronic printed circuit boards at the upcoming IPC APEX EXPO™ in Las Vegas, NV (April 6-8, 2010). Rogers will showcase its Theta™, RO4360™, RT/duroid® 5880LZ, and RT/duroid 6202PR product lines at IPX APEX EXPO 2010 (www.ipcapexexpo.org), one of the leading events for PCB products, technologies and test techniques.
Members of Rogers Advanced Circuit Materials Division will be on hand at Booth # 1125 to offer advice and guidance on the use of their high performance PCB materials, including Rogers’ halogen-free, RoHS-compliant Theta circuit materials that offer superior thermal and electrical performance. With a stable dielectric constant of 3.90 and low dissipation factor of 0.008 at 1 GHz, Theta materials are ideal for high-speed telecommunications and computing applications, and are an environmentally-friendly solution for the high reliability, high speed digital market. Tomorrow’s high reliability requirements are addressed today with a very low coefficient of thermal expansion (CTEz) of about 50 ppm/ºC (approximately 30% lower than standard FR-4).
Rogers RO4360 high-frequency laminates are glass-reinforced, ceramic-filled thermoset materials that combine high performance with ease of processing. Although they support low-cost processing such as used with FR-4 material, RO4360 laminates feature a dielectric constant of 6.15 (matching competitive PTFE products) and low loss with a dissipation factor of 0.003 at 10 GHz. They also boast high thermal conductivity for use in high-power circuits, such as power amplifiers, and low CTE of 30 ppm/ºC in the z direction for high PTH reliability in multilayer circuits. They are compatible with lead-free processing and automated assembly methods.
RT/duroid 5880LZ high-frequency laminate materials are PTFE-based composites with a unique filler with a very low density (specific gravity of 1.37 g/cm3) for weight-sensitive applications. With a dielectric constant of only 1.96 at 10 GHz, maintained to a tolerance of ±0.004, RT/duroid 5880LZ materials provide impressive consistency across a board and from board to board. The laminates also minimize losses with a dissipation factor of typically 0.0019 at 10 GHz.
