Properties of Panasonic MEGTRON M R-5735 Laminate

Panasonic MEGTRON M R-5735 laminate has some distinct properties:

Low water absorption rate

The water absorption rate of this material is 0.14%. This indicates a low water absorption rate. Also, low water absorption rate contributes to its thermal performance. This means that this material can hardly absorb water when immersed in it.

Low dissipation factor

The dissipation factor of this laminate is extremely low. Also, Panasonic MEGTRON M R-5735 features a Df value of 0.005 and 0.007 at 1 GHz and 10 GHz respectively. Dissipation factor measures the degree of loss when electricity in an insulator system is discharged. Very low Df materials are a better insulator.

High decomposition temperature

The Td value of Panasonic MEGTRON M R-5735 is 360 degrees per Celsius. With a high decomposition temperature, this material can function well under a high temperature without decomposing chemically. A Td value of 360oC means this material will start decomposing chemically when subjected to a temperature above this degree.

High glass transition temperature

The glass transition temperature of this material is 195oC at DSC. At DMA, this value is 210oC. The Tg value changes to 185oC at TMA. Tg offers different results when measured with different thermal analysis. However, the Tg of this material is high irrespective of the thermal analysis technique used.

Low dielectric constant

The dielectric constant of Panasonic MEGTRON M R-5735 is very low. Also, this laminate features a Dk value of 3.9 at 1 GHz and 10 GHz.  It maintains a stable Dk across a wide frequency and temperature range. This is a great advantage for PCB fabrication.

Low CTE value

The Z-axis CTE value of this material is 31 ppm/oC. Therefore, this material can hardly expand in size when exposed to different thermal conditions.

Advantages of Panasonic Halogen-free MEGTRON M R-5735 Laminate

Low loss material

One of the major concerns in high frequency PCB application is signal loss. Therefore, it is vital to use material that features low transmission loss. Also, this low loss material ensures high data transmission. Also, Panasonic MEGTRON M R-5735 laminate is ideal for use in the communication industry.

Environmentally safe

Halogen is a toxic material for PCB fabrication. Also, it is very harmful to humans and the environment. Panasonic MEGTRON M R-5735 laminate is free of halogen constituents.  Therefore, it is environmentally safe. Halogen constituents include bromine, fluorine, and chlorine. These substances are very dangerous.

High heat-resistance

Panasonic MEGTRON M R-5735 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 MEGTRON M R-5735 laminate features flame retardation. Also, it meets the specifications of other industry standards.

Great performance

This is another benefit of using Panasonic MEGTRON M R-5735 laminate for PCB fabrication. Panasonic MEGTRON M R-5735 laminate performs well both thermally and electrically. Also, this material is electrically stable over a wide frequency range.

The Effect of Low Dielectric Constant on Panasonic MEGTRON M R-5735 Laminate

A material’s dielectric constant has a huge effect on its performance. It measures a material’s capacity to store electrical energy. Also, materials commonly used in the communication need to have low dielectric constant. In addition this value should be stable over a wide frequency range. The dielectric constant is an electrical property that determines signal integrity.

A material’s dielectric constant changes with frequency. A low dielectric constant enhances high-frequency performance. This feature has a great impact on the performance of Panasonic MEGTRON M R-5735 laminate.

Panasonic MEGTRON M R-5735 laminate is widely used in communication systems. This is due to its low dielectric constant. With this low Dk value, this material enhances signal transmission. Also, the low dielectric constant reduces signal loss. Low dielectric materials are more efficient. When signal integrity and impedance control are crucial, a low dielectric material is the right choice.
