Arlon Material PCB

March 23. 2023

Arlon PCB Materials for Electronics (MED) is a division of Arlon LLC, a leading manufacturer of specialist high performance laminate and prepreg materials used in a wide range of PCB (printed circuit board) applications. These applications frequently necessitate laminates with unique electrical, thermal, mechanical, or other performance characteristics that outperform common FR-4 materials.

Arlon Electronic Substrates is a thermoset resin technology company that specializes in polyimide, high Tg multifunctional epoxy, and low loss thermoset laminate and prepreg systems. These resin systems are available on a number of different substrates, including woven glass and non-woven aramid. Advanced commercial and military electronics such as avionics, semiconductor testing, heat sink bonding, High Density Interconnect (HDI), and microvia PCBs are typical applications for these materials (i.e. in mobile communication products).

Fluoropolymers (like PTFE), fluoropolymers filled with ceramic, and low loss ceramic hydrocarbon thermoset laminates are the areas of expertise of Arlon Microwave Materials. These materials provide the electrical performance required in frequency-dependent circuit applications like base station antennas, phased array radars, power amplifier boards, communications systems, and a variety of other antenna applications. An intriguing product is CLTE-XT, a lower loss variant of CLTE. The CLTE-XT is the product in its class with the lowest loss, lowest thermal expansion, maximum phase stability, and lowest moisture absorption.

Arlon PCB Material Characteristics

Due to the many materials lying under its classifications of Arlon Polyimide products, low flow products, epoxy products, and SMT or controlled thermal expansion product material classes, Arlon printed circuit materials have a variety of features. Prior to discussing various product-specific characteristics, it is crucial to recognize that all Arlon products share some characteristics. These qualities consist of the following.

Glass transition temperature is high. All Arlon printed circuit board materials have a high glass transition temperature, whether Arlon laminate, Arlon fabric, or other integrated circuit materials. Remember that glass transition refers to the continuous and reversible change of an amorphous substance from its strong and brittle glassy state to a rubbery or viscous state when subjected to a temperature increase.

Dielectric thermoset with little loss. Because all Arlon PCB materials have a low loss thermoset, they cannot heat up quickly when operating in high RF environments. Polyimide, silicone, and PTFE, among other materials, are excellent examples.

Polyimide. In this example, it is an Arlon polymer composed of imide monomers from the high-performance plastics category. Because of its great heat resistance, the material can be used in a variety of applications that require tough organic ingredients. As a result, it is used in high-temperature displays, fuel cells, military applications, and so on.

Yet, each Arlon material category has its own set of material goods, each with its own set of characteristics. As a result, if you wish to design an Arlon printed circuit board, you must understand these specific Arlon materials and their accompanying properties in order to assure a quality and functional Arlon PCB.
