    RayMing has long been famous in the advanced electronic PCB material industry for a long time. Using materials that "help strengthen, protect and connect our world", RayMing provides many types of materials to solve problems in many areas.

Rogers 5880 laminates are manufactured with the same high-quality, reliable materials and processes as Rogers, enabling Rogers to win important awards from high-frequency material manufacturers. In some designs, the dielectric properties of the PCB are critical. Whether it is high speed, radio frequency, microwave or mobile, power management is the key. You will find that there are more cases where the dielectric properties of the circuit board are required in the prototype than the standard FR-4 cannot provide. We know. This is why we extend PCBExpress with Rogers5880 dielectric material. These new low-loss dielectric materials mean higher performance for demanding PCB prototypes.

 

Why use RogersDielectric material?

       FR-4 material is the basic standard for PCB substrates, which can achieve an efficient balance between cost, manufacturing capacity, electrical performance, and durability, and performance. But if electrical characteristics and advanced performance are the basis of your design, Rogersmaterials is your ideal choice because:

     1.Reduce dielectric loss

     2.Low loss electrical signal

     3. Large range value Dk (dielectric constant) value (2.55-10.2)

     4.Low-cost circuit manufacturing

    5.Low air free space application

RayMing can now provide industry-leading RF design, microwave and mobile devices with the delivery time, quality and benchmarks required for all our services, but now has the better performance of PCB materials.

Dielectric material

     Dielectric materials are substances with poor conductivity and are used as insulating layers in PCB structures. Porcelain, mica, glass, plastic and some metal oxides are good dielectrics. The lower the dielectric loss (energy lost in the form of heat), the more effective the dielectric material is. If the voltage in the dielectric material becomes too large, that is, when the electrostatic field becomes too strong, the material suddenly starts to conduct current. This phenomenon is called dielectric breakdown.

     Properties of RTDuroid5880

     Very low electrical any chance of loss of reinforced PTFE material

     Low moisture absorption

     Isotropic

     Electrical properties with uniform frequency

    Excellent chemical resistance, including solvents and reagents for printing and coating

    Friendly environment

Pre-impregnation (Pre-Preg)

     The shrinkage of "pre-impregnated composite fibers" and the production of PCBs, pre-pregs, will affect the performance characteristics of printed circuit boards. A term used in the PCB manufacturing industry to describe the material multilayer PCB used to connect the adhesive layer of the layer.

RTDuroid5880 high frequency laminate from Rogers

        The Rogers5880 high-frequency laminate series use PTFE composite materials to enhance glass fiber. These microfibers are statistically oriented to maximize the advantages of fiber gain, providing the most valuable direction for circuit manufacturers and end-use applications. The dielectric constant of these high-frequency laminates is the lowest of all products, and the low dielectric loss makes it suitable for high-frequency/broadband applications where dispersion and loss must be minimized. Due to its extremely low water absorption performance, RTDuroid5880 is very suitable for use in high humidity environments.

Rogers 5880 laminated PCB

       These advanced circuit materials can be easily cut, sheared and processed to form any solvents and reagents or edge and hole plating commonly used in circuit boards. They have very low electrical losses for any reinforced PTFE material, and they also have very low hygroscopicity and are also isotropic. They have uniform electrical characteristics in frequency. The high-frequency RTDuroid5880 is used in commercial telephone company airlines, microstrip and stripline circuits, millimeter wave system applications used by military radars, missile system antennas, digital radio dot show and others. RTDuroid5880 filled with PTFE compound is specially designed for the rigorous applications of integrated circuits and microcircuits.

      RogerPCB material has the lowest DK value of copper laminate currently available on the market. Due to its low dielectric constant of 1.96 at 10GHz, RTDuroid5880 supports broadband applications at microwave frequencies in the millimeter range, where dispersion and circuit loss must be minimized. It is a single-filled, lightweight PTFE composite material with extremely low density (1.37g/cm3) and low coefficient of thermal expansion (CTE) on the Z axis, which can provide high-frequency manufacturing (PTH) holes and achieve higher In addition, the dielectric constant from board to panel is uniform and constant over a wide frequency range, and the Z-axis TCDk is as low as +22ppm/°C.
