PTFE/Woven Fiberglass/Micro-Dispersed Ceramic Filled Laminate for RF & Microwave Printed Circuit Boards

AD255C combines the superior thermal properties of a fluoropolymer resin system with selected ceramic materials and fiberglass reinforcement to yield a laminate material with lower loss (Df=0.0014 at 10GHz), lower thermal expansion properties and lower passive intermodulation (PIM). AD255C also represents further improvements over Arlon's AD255A product in terms of cost.

Stability of PTFE over wide frequency and temperature ranges with low loss properties, makes AD255C ideal for a variety of microwave and RF applications in telecom infrastructure. The inclusion of micro-dispersed ceramic provides thermal stability to the laminate in the form of lower CTE values and greater phase stability across temperatures.

The net combination of properties of AD255C are highly desired in applications where higher frequency and expectations for longevity in material performance for high gain and broadband signals, which are typically beyond the performance capabilities offered by low loss thermosets. AD255Cis compatible with the processing used for standard PTFE based printed circuit board substrates. Its low Z-axis thermal expansion improves plated through-hole (PTH) reliability compared to typical PTFE based laminates. Low X-Y expansion improves BGA solder-joint reliability.
