What sets Arlon PCB apart from other materials?

Arlon, a term we come across in electronics manufacturing and design every day. It is often easily overlooked but it has an intriguing history. As you well know, printed circuit boards are vital for all electronic devices. Arlon PCB, a prime example of high performance and quality printed circuit board, becomes ideal for your electronic needs, especially if you have unique application areas that need superior PCB capabilities. It, however, becomes crucial to trust an ideal PCB manufacturing and assembly partner in RayMing PCB and Assembly to ensure quality Arlon PCBs for your use. But before you engage us or any other Arlon manufacturing company, let us first understand what an Arlon printed circuit board means.

Arlon Printed Circuit Board

You can always bank the idea of circuit boards and electronics devoid of the appropriate fabrication materials as wishful thinking. Circuit board materials represent a fundamental aspect of the design, production, and performance of PCBs. It is with this background that this article will approach the entire subject of Arlon PCB.

So what is Arlon PCB? It implies a circuit board manufactured with materials from Arlon LLC. The company contains a division specializing in materials for electronics (MED) that features high-performance Prepreg and laminate materials. Such materials are deployed in diverse application areas that demand specialized mechanical, thermal, electrical, and other vital attributes that surpass traditional FR-4 resources and materials.

Therefore, it becomes crucial for you to get a top Arlon PCB manufacturer with the capacity to source for every Arlon material needed and offer fabrication and assembly services for your PCB design needs and at an agreeable cost.

Arlon PCB Materials

What sets Arlon apart from other materials is the unique chemical composition that makes it such a reliable and versatile material for industrial use. Arlon’s versatility is attributable to the unique properties which make it suitable for a number of different purposes, such as manufacturing, design, construction and testing. It has peculiarities in its chemical composition which make it ideal for addressing all these needs.

As alluded to, Arlon PCBs have become a reality with quality Arlon PCB materials. Arlon electronic materials comprise substrates, conductive layers, etc. However, all Arlon electronic substrates or Arlon laminates possess distinct features, courtesy of the thermal resin technology deployed in their manufacture. It is a technology that incorporates high glass transition multifunctional epoxy, low loss thermoset, and polyimide Prepreg and laminate systems. Such resin systems become available on diverse substrates encompassing non-woven aramid and woven glass.

The conducting layer, mostly copper, always remains the same as other FR-4 based printed circuit boards, though it comes a little thicker. However, the Arlon microwave material focuses on fluoropolymers filled with ceramic and hydrocarbon thermoset laminates with low-loss ceramic. It is a pool of materials that guarantees the required electrical performance in the frequency-dependent printed circuit board applications like communication systems, phased-array radars, base station antennas, power amplifier boards, and other areas/applications that rely on the antenna.   

Features of Arlon PCB Materials

Arlon printed circuit materials have diverse properties owing to the different types of materials falling under its classes of Arlon Polyimide products, low flow products, epoxy products, and SMT or controlled thermal expansion product material classes. However, before tackling some product-specific attributes, it becomes important to acknowledge that all Arlon products have common features. Such attributes include the following.

  • High glass transition temperature. All Arlon printed circuit board materials, whether Arlon laminate, Arlon fabric, or other integrated circuit materials, possess a high glass transition temperature attribute. To better understand this, remember that glass transition implies the steady and reversible change of an amorphous substance from its tough and brittle glassy state to a rubbery or viscous state when subjected to a temperature increase.     
  • Low loss dielectric thermoset. All Arlon PCB materials have a low loss thermoset, which means they cannot heat up quickly when operating in high RF situations. An excellent of such material includes polyimide, silicone, or PTFE, among other material types.
  • Polyimide. In this case, it comes as an Arlon polymer, comprising of imide monomers under the high-performance category of plastics. Such a high heat resistance property allows the material to get deployed in diverse applications that need rugged organic constituents. Because of this, it gets deployed in the high-temperature display, fuel cells, military applications, etc.  

However, each category of Arlon materials has specific material products, with each possessing specific features. Therefore, if you want to design an Arlon printed circuit board, you cannot escape the significance of understanding these specific Arlon materials and their corresponding attributes to ensure quality and functional Arlon PCB.
