Advantages of the High Dielectric Constant of the RO 3210 Laminates

Today, PCB materials having high dielectric constants can be employed in power antennas and amplifiers involving large volumes.

Although PCB materials having a high dielectric constant have many benefits, which are mostly based on delivering power integrity, people don’t usually consider them. A good number of fabricators usually prefer to choose PCB materials having low dielectric constant (Dk) over those with high Dk for high-speed applications and high frequency due to their low loss tangent.

Below are some of the advantages of choosing a PCB material with high Dk:

Thermal Conductivity is Much Higher

Materials having high Dk made from PTFE, and are ceramic filled like RO 3210, usually have higher thermal conductivity. Asides from their better heat-skin designs, these materials provide heat transfer from active components and devices into heat sinks.

Optimal Economics

The use of materials with high Dk will help in producing multilayer PCBs. Here, just a few layers prove critical for the operation of the microwave. Also, PCB materials with low cost can be used in scenarios like this.

A multilayer stack-up with high Dk material can ensure the separation of ground power and planes thereby causing lower transfer and self impedance.

Also, a material with lower Dk in the stack-up makes sure that the signal is well supported in the interior and surface layers of a sufficiently encased stripline.

The ro3210 also delivers a unique opportunity for fabricating antennas having reduced element area. You can make use of an easy plasma process in navigating through the costs involved in preparing through-holes that are plated.


With a high dielectric constant material like the roger ro3210, the dimension of your circuit can be reduced at a specific frequency. This material can also reduce electromagnetic waves’ phase velocity. They also function using smaller circuits and shorter wavelengths. Miniaturization comes with these benefits:

  • Better Coupling
  • Reduced radiation losses
  • Slow-wave signal propagation/enhancement
  • Higher-order modes reduced
  • Reduction in circuit size
  • Delays possible fluctuations between different components of PCB significantly
  • Lesser transfer impedance

Is it Possible to Construct a PCB with Multilayer Using RO 3210?

It is possible. The rogers ro3210 laminate is a great material for multilayer PCB fabrication. It features an in-plane expansion with a low coefficient, which makes it great for constructing an epoxy hybrid multi-layer PCB design.

Majorly, the electrical performance and mechanical characteristics of the rogers RO3210 material are stable, which is great for other laminates of the RO 3200 series.

The mechanical properties consistency also makes it possible to utilize materials having different dielectric constant on individual layers without going through incompatibility or warpage issues.

It can be used along with other less expensive materials to reduce the cost of production.

What Features of the Rogers RO3210 Laminate makes them Appropriate for High-Frequency Application?

Ro3210 laminates can be used for high-frequency radio frequency and commercial microwave applications. The suitability of this laminate in high-frequency applications can be seen in the features below:

  • It has a high Dielectric constant value of 10.2
  • The coefficient of thermal expansion is low
  • Has the V-0 rating for the UL flammability test and works fine with processing techniques that are lead-free.
  • The dissipation factor is low at 0.0027
  • Suitable for use in applications running above 40 GHz
  • The dimensional stability is great

What Must You Consider Before Making Use of the RO 3210 Laminate?

The following should be considered when choosing this laminate for any PCB project:

  • The thickness and size of the panel
  • Copper-clad size and type used
  • Installation space size
  • Impedance control
  • Turnaround time
  • Equipment and manufacturability capability
