Introduction:
It's very happy to introduce our newly shipped PCB which made of RO4003C laminates. RO4003C laminates are cost-effective microwave materials known for their precise control over dielectric constant (ε) and low loss. They are available in different configurations, utilizing 1080 and 1674 glass fabric styles. Unlike PTFE-based microwave materials, RO4003C laminates do not require special handling procedures or through-hole treatments. These laminates are non-brominated and do not have a UL 94 V-0 rating.
Features:
RO4003C laminates are composed of woven glass reinforced hydrocarbon/ceramics. They have a dielectric constant (DK) of 3.38 ± 0.05 at 10 GHz and a dissipation factor (tan δ) of 0.0027 at the same frequency. The laminates exhibit a thermal conductivity of 0.71 W/m/°K. The coefficient of thermal expansion (CTE) is 11 ppm/°C in the X-axis, 14 ppm/°C in the Y-axis, and 46 ppm/°C in the Z-axis. The glass transition temperature (Tg) is greater than 280 °C, and the laminates can operate within a temperature range of -40℃ to +85℃.

Benefits:
RO4003C laminates offer excellent electrical performance with low dielectric tolerance and low loss. They maintain stable electrical properties across a wide frequency range. The laminates exhibit a low thermal coefficient of dielectric constant, providing dimensional stability. They also offer reliable plated through holes with low Z-axis expansion. With a low in-plane expansion coefficient, RO4003C laminates remain stable over a range of circuit processing temperatures. Moreover, these laminates are cost-effective compared to conventional microwave laminates. They are also resistant to conductive anodic filamentation (CAF).
