Product Details Data Sheet

The dielectric loss of Rogers ro3003 PCB is very low. Even if the working frequency reaches 10 GHz, the dielectric loss factor is only 0.0013. Moreover, ro3003 also has excellent electrical and mechanical properties. At the same time, the laminate has high cost performance, mainly for commercial microwave and RF applications.


Rogers ro3003pcb is made of PTFE Composites Based on ceramic filling. The melting point is as high as 327 degree Celsius. It has strong acid-base resistance and high-temperature resistance, which ensures the normal operation of the circuit in harsh environment. Therefore, it can be used as an ideal circuit material for special applications. In addition, the thermal expansion coefficient (CTE) of ro3003 in X and Y directions is 17 ppm / degree Celsius, which is equivalent to that of copper. The shrinkage of one inch material after etching and baking is less than 0.5 mil. The thermal expansion coefficient in Z direction is 24ppm / degree Celsius, which can ensure the stability of electroplated through-hole even in severe thermal environment.


Because the step phenomenon of dielectric constant of PTFE glass cloth material near room temperature is eliminated, the change of dielectric constant of ro3003 with temperature is very stable. Regardless of the dielectric constant, Rogers ro3003 PCB material has stable mechanical properties, which ensures that designers will not encounter warpage or reliability problems when developing multilayer boards.


Rogers ro3003 PCB material can be processed by standard PTFE PCB technology. Its typical applications are: automotive radar, GPS antenna, power amplifier and antenna in cellular communication system, patch antenna in wireless communication, live satellite, remote meter reading, power backplane, and data link of wired system.

Rogers ro4835 is a kind of high frequency circuit board material filled with hydrocarbon resin and ceramics, which belongs to civil products. It has the ability of compatible with FR4 mixed pressure, FR-4 processing technology and lead-free welding process. At 10 GHz, the dielectric constant in Z direction (thickness direction) of Rogers Rogers ro4835 is 3.48, and the tolerance is ± 0.05. The thermal conductivity of the material is 0.69 w / M / ° K, and it has very good dimensional stability in the X-Y plane.


With the change of time and temperature, the oxidation will affect all the thermosetting boards, and the dielectric constant and loss factor of PCB will increase slightly. The higher the working temperature of the product is, the faster the dielectric constant and loss factor of PCB board will be increased due to oxidation.


The materials, electrical and mechanical properties of Rogers ro4835 are almost the same as those of ro4350b. The biggest difference between Rogers ro4350b high frequency circuit board material and ro4835 high frequency circuit board material is that the antioxidant is added to ro4835. Compared with the traditional thermosetting material, the oxidation resistance is increased by 10 times, and it meets the requirements of ipc-4103 (high speed and high frequency substrate specification). In addition, the dimensional stability, hardness and water absorption of ro4835 are better than that of ro4350b. However, the temperature characteristic of the DK of ro4835 is relatively poor, which requires high temperature range of the product, especially the thermal expansion coefficient of z-axis becomes worse, and the phase characteristic of high frequency is relatively poor. It is better to avoid using the product with strict requirements on phase.
