What is the Panasonic R-A555(W) Laminate?
Panasonic R-A555(W) PCB material is a high-heat-resistant, halogen free multilayer material. It provides excellent impedance matching due to its ultra-thin insulated layer with low Dk. This enables thinner and more compact designs for mobile products. The Panasonic R-A555(W) PCB material demonstrates a Tg value of 160°C as measured by the TMA method, and a glass transition temperature (Tg) of 200°C determined via the DMA method. The glass transition temperature signifies the threshold at which the material transitions from a ductile to a brittle and rigid state, typically occurring at a lower temperature than the melting point of the material’s crystalline phase.
In today’s fast-paced technological landscape, the trend toward miniaturization continues to grow. The Panasonic laminates are designed to support this trend by facilitating advanced technologies across various industries. For instance, in consumer electronics, these laminates contribute significantly to the development of cutting-edge smartphones and tablet PCs. These devices require not only superior performance but also sleek and ergonomic designs that appeal to users.
Moreover, the material finds application in more specialized fields such as automotive technology. In particular, it supports the creation of in-vehicle autonomous driving servers, which demand high reliability and durability under varying conditions. The halogen-free composition of the R-A555(W) ensures environmental friendliness while maintaining robust performance characteristics necessary for such critical applications.
Overall, the Panasonic PCB material represents a significant advancement in substrate technology. By combining heat resistance, low Dk properties, and compatibility with ultra-thin layers, it empowers manufacturers to push the boundaries of what is possible in terms of design and functionality. Whether used in everyday gadgets or sophisticated systems like autonomous vehicles, this material demonstrates its versatility and importance in shaping the future of electronics.

Features of Panasonic R-A555(W) Laminate
Panasonic R-A555(W) laminates are engineered to meet the performance requirements of advanced electronic systems. Below are some of the most important material properties:
Glass Transition Temperature (Tg)
The Tg of R-A555(W) is approximately 200°C, which ensures the laminate maintains its structural integrity under higher thermal conditions. This makes it suitable for applications that require stable performance at elevated temperatures.
Decomposition Temperature
The laminate possess a high decomposition temperature, which indicates excellent resistance to thermal degradation. The Panasonic R-A555(W) PCB material has a decomposition temperature of 380 degrees Celsius. This is especially important in applications that involve exposure to high temperatures, ensuring the longevity and stability of the material throughout its lifecycle.
Dielectric Constant (Dk)
R-A555(W) features a dielectric constant of around 3.4 at 1 GHz, ensuring reliable signal integrity and minimal signal loss in high frequency circuits. This laminate material maintains a stable Dk, ensuring consistent electrical performance across a range of frequencies, which is crucial for high-speed data transmission in modern electronics.
Dissipation Factor (Df)
The dissipation factor of R-A555(W) is low, generally around 0.008 at 1 GHz, indicating that it exhibits minimal energy loss during signal transmission. This property is essential for high frequency applications where signal attenuation can impact system performance.
Coefficient of Thermal Expansion
At the X and Y axis at α1, the Panasonic R-A555(W) laminate has a CTE value of 11 – 13 ppm/℃. Furthermore, at the Z-axis and α1, it has a CTE value of 37 ppm/℃, while at α2, it’s CTE is 170 degrees Celsius. The coefficient of thermal expansion indicates how much a material can expand when it is heated.
Low Water Absorption
Low moisture uptake preserves electrical characteristics over the product lifecycle and enhances reliability in humid environments. The water absorption value of the Panasonic R-A555(W) PCB material is 0.07%. This means that this material doesn’t absorb water easily.
Applications of Panasonic R-A555(W) Laminate
Panasonic R-A555(W) laminates are utilized in various industries that demand high reliability, performance, and durability. Some of the key applications include:
