Rogers RO3003+RO4835+lsola 370HR PCB

The dielectric loss of Rogers Ro3003 PCB is very low, and the dielectric loss factor is only 0.013 even when the operating frequency reaches 10GHz.
In addition, R03003 also has excellent electrical and mechanical properties. At the same time, the laminate has a high cost-effectiveness and is mainly used in commercial microwave and RF applications.

Rogers Ro3003 PCB is made of PTFE composite material based on ceramic matrix, with a melting point of up to 327 degrees Celsius.
It has strong acid and alkali resistance and high temperature resistance, which ensures the normal operation of the arc in harsh environments,
So it can be used as an ideal circuit material for special applications. In addition, the thermal expansion coefficient CTE of Ro303 in the X and Y directions is 17μm/℃, which is comparable to copper.
The material shrinkage rate after etching and baking is less than 0.5mil, and the thermal expansion coefficient in the 2 direction is 24μm/℃,
Which can ensure the stability of plated through holes even in harsh thermal environments.

Due to the step phenomenon of the dielectric constant of PTFE glass cloth material near temperature, the change of Ro3003 dielectric constant with temperature is very stable.
Ro3003 PCB material has stable mechanical performance characteristics regardless of dielectric constant, ensuring designers will not encounter warpage or reliability issues when developing multi-layer boards.

Booers RO3003 PCB material can be processed using standard PTFE PCB technology, and common applications include automotive radar, GPS navigation,
Power amplifiers and antennas in cellular communication systems, antenna wiring in wireless communications, satellite, remote meter reading, power backplanes and data links in wired systems.

Rogers RO4835 is a high-frequency circuit board material made of hydrocarbon resin and ceramic. It is a civilian product that is compatible with FR4,
R-4 processing technology and lead-iron welding technology.
The dielectric constant of Rogers 4835 in the Z direction (thickness direction) at 10GHz is 3.48, with a tolerance of 0.05.
The thermal conductivity of the material is 0.69w/M/°K, and it has very good dimensional stability in the X-Y plane.

As time and temperature change, oxidation will affect the circuit board, and the dielectric constant and loss factor of the PCB will increase greatly.
The higher the operating temperature of the product, the faster the dielectric constant and loss factor of the PCB board will increase due to oxidation.

The material, electrical and mechanical properties of Rogers 4835 are almost the same as Ro350b.
The biggest difference between Rogers 4835 high-frequency circuit board material and Ro350b high-frequency circuit board material is that by adding antioxidants to 04835,
The anti-oxidation performance is improved by more than 10 times compared with traditional thermosetting materials, and the melt flow rate and substrate hardness requirements of IPC-4103 are met.
The dimensional stability, hardness and water absorption of Ro4835 are better than Ro4350b,
But Ro4835 has poor DK temperature characteristics, requiring the product to be used in a high temperature range, especially the Z-axis expansion coefficient is poor.
The high-frequency phase characteristics are relatively poor, and it is best to avoid using products that strictly rewire the BHA
