Arlon AD260C PCB materials have gained recognition for their exceptional performance in high-frequency applications. With their low dissipation factor, excellent dielectric constant control, and thermal stability, these materials have become a preferred choice for demanding RF and microwave circuit designs. This article provides an overview of the key characteristics, benefits, and considerations associated with Arlon AD260C PCB materials.

Background of Arlon C series PCB Materials

In response to the rapid expansion of the wireless industry during the 1990s, Arlon LLC embarked on the development of the AD Series materials to cater to the cost-sensitive commercial antenna and satellite markets. This initiative involved leveraging PTFE and woven fiberglass in strategic combinations to produce a range of materials with lower dielectric constants, spanning from 2.50 to 3.50. Notable products from this endeavor included AD250L™, AD260L™, and AD320L™, each offering various thickness options to meet market demands. While construction options were abundant, they were somewhat constrained by the physical limitations of commercially available glass styles. These materials found significant success in the antenna market for several years.

Over time, there emerged a growing need for more cost-effective versions of the “L” series products. In response, Arlon formulated ceramic-filled layers to replace some of the pricier unfilled resin layers, resulting in the second generation or “A” version of the AD Series materials. Examples of these included AD255A™, AD300A™, and AD320A™. In addition to being more economical, the “A” series products exhibited lower z-axis expansion rates and lower dissipation factor values, partly attributable to a reduction in glass content. While this newer construction limited the range of available thickness options, the resulting products were more cost-effective and demonstrated improved performance, presenting clear benefits to customers.

To further drive down manufacturing costs, Arlon introduced the “C” series versions of select AD Series products. This final “C” series achieved cost reduction through the incorporation of additional ceramic-filled layers and reduced resin content, leading to further reductions in z-axis expansion and dissipation factor. Notable examples of these materials include AD250C™, AD255C™, and AD300C™. The “C” series versions have proven to be the best overall value for our customers, offering superior performance at the lowest price point.
