Rogers RO3730 laminates are high-frequency circuit materials that meet the requirements of high-speed and high-temperature applications. With a Dk of 3.0 and a 0.0013 dissipation factor, RO3730 allows designers of antennas to minimize signal loss.

Due to the mechanical and electrical properties of this material, it is needed in the fabrication of PCBs with high-frequency demands. RO3730 laminates can be transformed into PCBs with the use of the processing techniques of the PTFE circuit board. Rogers Corporation specifically designed Rogers RO3730 to meet the increasing demands of antenna designers. Using clad and woven fiberglass, they are reinforced with electrodeposited copper foil.

Properties of RO3730

Rogers RO3730 offers impressive signal transmissions and electrical qualities. These laminates also feature great thermal, electrical, and mechanical properties which include:

Low dielectric constants: Rogers RO3730 has a low dielectric constant measured at 3.0 at 10GHz at 23°C. This value shows that this material can retain its dielectric properties. An excellent dielectric constant is always measured between 2.4 and 4.6. With a dielectric constant of 3.0, this laminate is ideal for use in high-frequency pcb applications.

Low dielectric loss tangent: The dielectric loss tangent of a circuit material is also regarded as the material’s dissipation factor. With a loss of tangent measured at 0.0013 in 10GHz/23°C, this material will perform well over different frequencies. One of the commonest quality designers consider is a low dielectric loss tangent.

Low dimensional stability: The dimensional stability of Rogers RO3730 measured at both axis X and Y is 0.02 and 0.03mm/m.

Coefficient of thermal expansion: The CTE of Rogers Ro3730 can be measured at 12 and 13 ppm/°C in the X and Y direction. CTE measures how a material expands in response to a change in temperature.

Excellent thermal conductivity: This material has a thermal conductivity of 0.45 W/m/°K. The thermal conductivity of Rogers RO3730 is high. This means that thermal energy can be transferred by the material with ease. When a circuit material has high thermal conductivity, it helps in contributing to the better performance of multilayer boards.

Low moisture absorption: This material’s moisture absorption is 0.04%. It has a low rate of moisture absorption and as such, makes it withstand a humid environment.

Great peel strength: Rogers RO3730’s peel strength is measured at 1.8 N/mm at 10 sec. 550°F. The peel strength measures the strength of the bond between the substrate material and the conductive layer. The peel strength of RO3730 is excellent.

Satellite radio antennas: Rogers RO3730 laminates are ideal in the production of satellite radio antennas since they offer electrical qualities and reduce signal loss.

Frequently Asked Questions

How do I select a PCB material? When selecting a PCB material, you should consider the board application and design. The strength of your PCB substrate will be determined by the material you choose.  The type of conductive material you choose will also determine its conductivity levels.

Why is that the material always used in PCB for conductive layers is copper? Although you can make use of other materials such as gold and silver, copper materials are most usually utilized for this purpose. This is so, because copper functions as a great conductor of electrical signals. Asides from this, it is economical and readily available compared to gold and silver. It is also seen as a reliable thermal conductor.
