>Deep in the antenna array of 5G base stations, on the core circuit of 77GHz vehicle mounted radar, a special material is carrying lossless transmission of billions of high-frequency signals with micrometer level accuracy.
Rogers PCB, as a core material in the field of high-frequency electronics, has become a cornerstone carrier for 5G communication, millimeter wave radar, and satellite systems. Its revolutionary value lies in breaking through the high-frequency loss bottleneck of traditional FR-4 materials – when the signal frequency crosses the 10GHz threshold, the transmission loss of Rogers board is only 1/5 of FR-4, making stable communication in the millimeter wave frequency band move from theory to reality.

1、 Core feature: Redefine the physical limits of high-frequency circuits
The physical miracle of low dielectric loss
The loss tangent (Df) of Rogers materials can be as low as 0.001-0.004, and the dielectric constant (Dk) remains stable in a wide range of 2.55-11. Taking RO4350B as an example, its Dk value fluctuates only ± 0.05 at 10GHz high frequency, and Df is as low as 0.0037. This super stability enables 5G base stations in the 28GHz frequency band to achieve 10Gbps level data transmission.
Disruptive breakthrough in thermal management capability
-The thermal conductivity reaches 0.6-2 W/mK, which is 2-6 times that of FR-4
-The coefficient of thermal expansion (CTE) of the Z-axis is controlled at 32 ppm/° C, while the X/Y-axis is only 10-12 ppm/° C
-Decomposition temperature up to 390 ° C, resistant to lead-free soldering high temperature process
This thermal stability enables the 77GHz onboard radar to maintain a ± 0.1 ° angle measurement accuracy even at a high temperature of 125 ℃ in the engine compartment.
Micro scale size guardians
The moisture absorption rate is as low as 0.02-0.06%, and the deformation under humidity changes is less than 0.5%. In extreme operating conditions where the satellite orbit temperature suddenly changes by 200 ℃, the drift rate of the plate size is controlled within 2%, ensuring the beam pointing accuracy of the onboard phased array antenna.

The Art of Mixed Pressure Technology
Through vacuum lamination process (constant temperature of 170-200 ℃, pressure control of 200-400psi), molecular level binding of Rogers and FR-4 is achieved. A certain 5G equipment manufacturer integrated a 64 channel Massive MIMO antenna in a 50mm × 50mm space, with a laminated bubble rate of<0.1% and impedance control accuracy of ± 5%.

Electronic lifeline for deep space exploration
The gas release of RT/duroid 6002 is less than 0.1% (NASA standard requirement ≤ 1%), ensuring that the satellite has no performance degradation in orbit for 15 years. Its Z-axis CTE matches 98% with silicon chips, completely solving the problem of BGA solder joint cracking in on-board computers.
