AD260A Laminate from Arlon

Arlon’s AD260A is a woven fiberglass reinforced PTFE composite material designed as a low cost laminate with excellent low loss characteristics. Features of AD260A include lower loss through the use of optimizing the trade-off between thicker and thinner glass styles as well as a tighter DK tolerance.

This material combines the excellent low loss electrical properties of PTFE resin with the thermal properties of ceramic and the enhanced value of cost effective fiberglass styles to provide low cost laminate materials suitable for high volume commercial wireless communication applications.

The electrical properties of AD260A are highly desired in applications where higher frequency and expectations for increased fidelity with broadband signals are beyond the performance capabilities offered by high temperature or low temperature ceramics and thermosets.

The dielectric constant has been designed with a 2.60 dielectric constant. To maintain high yields with the end customer, Arlon uses the IPC TM-650 (FSR) Test Method on every panel to insure dielectric constant consistency. Stability of PTFE over a wide frequency range and its low loss properties, makes AD260A ideal for a variety of microwave and R/F 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 temperature.

AD260A is compatible with the processing used for standard PTFE based printed circuit board substrates. Its low Z-axis thermal expansion improves plated through hole reliability compared to typical PTFE based laminates. Low X-Y expansion improves BGA solder-joint reliability.
