Rogers (Arlon) AD Series: Advanced Microwave High-Frequency PCB Materials

Introduction to Rogers (Arlon) AD Series

The Rogers (Arlon) AD250C, AD255C, and AD260A represent the third generation of commercial microwave and RF laminates. These materials are distinguished by their low dielectric constants, cost-effectiveness, and exceptional low-loss characteristics, making them highly suitable for modern telecommunications infrastructure.

Cost-Effective Combination for Superior Performance

Rogers (Arlon) AD250C, AD255C, and AD260A microwave high-frequency PCB materials leverage a cost-efficient blend of composite chemistry and architecture. This combination delivers an unmatched price-performance ratio, essential for today’s demanding telecommunications applications.

Unmatched Thermal and Electrical Properties

These advanced materials integrate the excellent thermal properties of fluoropolymer resin systems with carefully selected ceramic materials and glass fiber reinforcements. The result is a series of laminates characterized by low loss (DF = 0.0014 at 10GHz), minimal thermal expansion, and reduced passive intermodulation (PIM). Notably, the AD250C variant also marks a significant improvement over previous generations in terms of cost efficiency.

Stability and Reliability Across Frequencies and Temperatures

The stability of PTFE combined with low-loss characteristics across a broad frequency and temperature range makes Rogers (Arlon) AD250C, AD255C, and AD260A ideal for various microwave and RF applications. The inclusion of differential dispersion ceramics enhances thermal stability, offering lower coefficients of thermal expansion (CTE) and higher phase stability at elevated temperatures.

Compatibility and Reliability Enhancements

Rogers (Arlon) AD250C, AD255C, and AD260A microwave high-frequency PCB materials are fully compatible with standard PTFE printed circuit board substrate processes. Their low z-axis thermal expansion significantly improves the reliability of plated through-hole (PTH) connections compared to typical PTFE base materials. Inoltre, low X-Y expansion enhances the reliability of BGA solder joints.

Material Composition and Advantages

The unique composition of Rogers (Arlon) AD250C, AD255C, and AD260A includes fluoropolymer resin, specific ceramic fillers, and glass fiber support materials. This combination yields dielectric laminates with low loss, robust mechanical toughness, stable dielectric constants, and low passive intermodulation (PIM).
