What is the Panasonic R-5575 PCB Material?
The Panasonic R-5575 PCB Material is known as a low loss, high speed halogen-free multilayer material. Furthermore, this material is very useful for Antenna and PA application.
In addition, this material is great for miniaturizing printed circuit boards. It also offers multilayer processability, anti-aging effect, low loss of transmission, halogen-free, and high thermal conductivity.
Let’s continue by discussing in detail what the properties of the Panasonic R-5575 PCB Material are as well as areas where they will be beneficial to you.
Properties of the Panasonic R-5575 PCB Material
Here, we will be dividing these properties into three main parts. These include the electrical properties, the mechanical properties, and the thermal properties.
Thermal properties involve the material’s properties, which relates to its ability to conduct heat. To explain further, we mean that these materials exhibit these properties when heat passes through it. The thermal properties of this material include the following
Glass transition temperature (Tg)
The Panasonic R-5575 PCB material has a Tg value of 205 degrees Celsius using the TMA test method. Using the DMA test method, it has a glass transition temperature of 245 degrees Celsius. This is the temperature at which glass transition occurs and it is usually lower in contrast to the melting temperature of the material’s crystalline state. At this temperature, the Panasonic R-5575 PCB material transforms from its ductile look to one that is brittle and hard.
The Panasonic R-5575 PCB material has a decomposition temperature of 440 degrees Celsius. The decomposition temperature is that temperature whereby this material will decompose chemically. Usually, an endothermic reaction occurs, because heat is usually needed to break the material’ chemical bonds when decomposition is on-going.
Coefficient of Thermal Expansion
At the X and Y axis at α1, the Panasonic R-5575 PCB material has a CTE value of 13 – 16 ppm/℃. Furthermore, at the Z-axis and α1, it has a CTE value of 20 ppm/℃, while at α2, its CTE is 155 degrees Celsius. The coefficient of thermal expansion indicates how much a material can expand when it is heated.
For the Panasonic R-5575 PCB material, its thermal conductivity value is 0.6 W/m·k. This value signifies the rate through which heat transfer takes place via conduction by the material’s cross-section area.
The physical properties of the Panasonic R-5575 PCB material include water absorption, flammability, and peel strength
The water absorption value of the Panasonic R-5575 PCB material is 0.23%. This means that this material doesn’t absorb water easily.
The peel strength of the Panasonic R-5575 PCB material is 0.8 kN/m. Generally, this value helps in measuring the material’s bond strength, most likely an adhesive.
The Panasonic R-5575 PCB material has a flammability rating of 94V-0.
The electrical properties of the Panasonic R-5575 PCB material include the dielectric constant, dissipation factor, volume resistance, and surface resistance.
The dielectric constant of the Panasonic R-5575 PCB material varies. At 1 GHz and 12 GHz, it has a value of 3.73 and 3.65 respectively. This property measures a material’s ability to store some electrical energy in a given electric field.
Just like the dielectric constant, the dissipation factor of the Panasonic R-5575 PCB material also varies. At 1 GHz and 12 GHz, it has a value of 0.002 and 0.004 respectively. This value indicates the Panasonic R-5575 PCB material’s efficiency to act like an insulator. Furthermore, the Panasonic R-5575 PCB material has a low dissipation factor, which means that it is very efficient as an insulating material.
Surface Resistance and Volume Resistance
The Panasonic R-5575 PCB material has a surface resistance value of 1 x 108 MΩ. Also, the volume resistance of the Panasonic R-5575 PCB material has a value of 1 x 109 MΩ-cm.
Benefits of Panasonic Halogen-free Panasonic R-5575 Laminate
The following are the benefits of the Panasonic R-5575 PCB Material.
Low loss material
One of the major concerns in high frequency PCB applications is signal loss. This is one good reason why it is very important to make use of a material that features a low transmission loss. Using a low loss material means that you will have high data transmission. Also, Panasonic R-5575 laminate is ideal for use in the communication industry.
Halogen is a toxic material for PCB fabrication. Also, it is very harmful to humans and the environment. Panasonic R-5575 laminate is free of halogen constituents. Therefore, it is environmentally safe. Some examples of halogen include bromine, fluorine, and chlorine, which are usually very dangerous.
Panasonic R-5575 laminate resists high heat. This helps to enhance reliable operation. Also, this multilayer PCB material offers high reliability in high temperature environments. The thermal properties of this material contribute to this feature.
UL 94 V-0 flammability
One of the benefits of this PCB material is that it meets the UL94 V-0 flammability standard. Therefore, Panasonic R-5575 laminate features flame retardation. Also, it meets the specifications of other industry standards.
This is another benefit of using Panasonic R-5575 laminate for PCB fabrication. Panasonic R-5575 laminate performs well both thermally and electrically. Also, this material is electrically stable over a wide frequency range.
We hope we have been able to explain what the Panasonic R-5575 PCB Material is and its properties. Also, this material comes with great benefits too. If you have any questions, feel free to reach out to us.
