Rogers 4003 Dielectric Constant

rogers 4003 dielectric constant

A PCB’s dielectric material is one that functions as a PCB’s insulating layer, which may have low electric conductivity. The materials here can be some metal oxides, plastic, porcelain, mica, or glass.

Just like other PCBs by Rogers, the Rogers 4003 dielectric constant is low. This is due to its construction material, which features a tight control and low loss over the dielectric constant.

Materials having low loss of dielectric constant are usually very effective. This is because they lose little heat energy. The Rogers 4003 dielectric constant is divided to design dielectric constant and process dielectric constant. The latter is the more preferred option to construct PCB.

The specification of the Roger 4003 Dk Process is 3.38 +/- 0.05. That of the Dk design falls within 3.55 +/- 0.05. It is less likely for the Roger 4003 PCB to suffer dielectric breakdown of any kind.

This breakdown occurs whenever the material begins to conduct current suddenly, due to the great electrostatic field caused by a voltage surge across it.

Rogers 4003 PCB Specifications

The Rogers 4003 comes with some specifications. These include:

  • For dimensional stability, this value is usually below 0.3 miles per inch (mils/inch)
  • Its material density is 1.79 gram per cubic centimeter (gm/cm3)
  • Its thermal coefficient value s about +40 ppm/C
  • The tensile strength is 141 megapascals (MPa), which is also equalto 20.45 kilopounds per square inch (Kpsi).
  • Dielectric constant is low and falls within 3.38 +/- 0.05
  • The dissipation factor is 0.0021 and 0.0027.
  • Transitional temperature value is greater than 280C DSC.
  • The coefficient of thermal expansion for the X coordinate is 11 ppm/C, for the Y coordinate it is 14 ppm/C and for the Z coordinate, it is 46 ppm/C.

Comparing RO4003 and FR4 Material

There’s one major difference between ordinary printed circuit boards and the ro4003. This has to do with their use. You can only use ordinary PCBs for a specific frequency range. This range is less than the range of ro4003 and other Rogers’ materials.

The RO4003 is useful in applications requiring high frequencies, higher than 500 Mhz. Ordinary PCBs, on the other hand, are not applicable with high frequencies. An ideal material for your PCB must have zero value for moisture absorption whenever you dip it into liquid. Majority of substances deliver an absorption value falling within 0.01% and 0.20%.

The absorption percentage is directly related with the material’s electrical and thermal properties. When the percentage of absorption is higher, then the influence it has on the material’s electrical and thermal properties will be higher as well. This will then help in reducing efficiency and performance.

If you compare them`with the ordinary type of PCBs, the RO4003 has the smallest value for absorption. This is why they are useful in unstable environments and difficult conditions. For example, we can use the ro4003 for defense and aerospace systems. The standard PCBs are useful in areas of low exhaust like standard switchboards.

Regarding price, both ro4003 and the standard printed circuit boards are different. The ro4003 is much more expensive. This is due to its high-quality. Regarding performance, the material of Rogers is also the best. This difference in price stated earlier has to do with the material you use and its quality.

Rogers 4003 Fabrication

rogers ro4003

The fabrication of the roger 4003 follows some procedures. This includes the pcb layout, core board production, etching of the inner core plate, core plate punching and inspection, lamination, drilling, and Core Plate Punching and Inspection.

PCB Layout

Inspecting and organizing the design of the roger 4003 must be the first step you should conduct in PCB fabrication. For homemade PCBs, you may print the design making use of the CAD software. You can do this on paper and then transfer to a laminate (copper clad).

For those dealing in large-scale production, try photocopying the design then get a film and print on it.

Next, arrange your photocopy pieces in multilayer PCB order.

Align your printed PCB. You can achieve this when you align the holes, then the materials necessary for the fabrication of the layers with respect to the alignment of the hole.

Core Board Production

You will start the production of the core when you transfer the layout of the innermost PCB. First of all, you do the construction of the two innermost core layers.

Next, clean up the layer of copper clad placing on its surface a film that is photosensitive. After this, let light get to it for the formation and curing of the protective layer.

Then insert the boards of the copper clad and the layout films of the PCB into the PCB layout’s upper layer. This stacks the lower and upper layout films of the PCB accurately.

Etching of the Inner Core Plate

Utilize strong bases such as sodium hydroxide (NaOH) in etching away copper foils you don’t want. Next, tear the photosensitive film off to the required copper foil of the PCB layout.

Core Plate Punching and Inspection

With this step, you’ll make holes in the board of the core. Then you align them. This is to help its compatibility when with other attached materials.

Inspection takes place through an automatic machine. This happens through comparison of the pressed printed circuit board to the initial drawing. It also searches for errors. Now, you are through with the initial two layers.


To handle this stage, there’s a need for a prepreg. This refers to a core board and a core, which binds the core board and the copper foil’s outer layer. This could also serve as an insulating material.

Lower iron plate and holes alignment assists in fixing the copper foil’s lower layer and the prepreg layers.

Next, place this core plate you’ve prepared on this alignment hole. Then, add two prepreg layers, then the layer of copper foil, and lastly cover the core using an aluminum plate layer, which bears the pressure.

Utilize a machine in compressing the stack up. This can be fixed also with the use of nails.

Next, transfer your compressed printed circuit board to a hot press. This performs the lamination process by holding under pressure, the core and copper foil, as well as melting of the epoxy.


With drilling, you will be able to connect the different layers of your printed circuit board. From the PCB’s top layer, perforate a hole by drilling down. Next, metalize this hole to ensure it conducts electricity.

With the X-ray machine for drilling, you will easily align this drilling into the core board’s holes. This ensures that the next hole for drilling passes through the hole’s center.

 Pore Walls’ Chemical Precipitation with Copper

This process takes place with a machine. It is important for connecting PCB walls making use of copper film of size 25-microns.

Making use of chemical decomposition, cover this hole and then spread your copper film of 1 micron. This helps in covering the whole surface of the PCB, as well as the hole.

Ro4003 Prepreg

The design of Ro4003 prepreg happens to ensure consistent performance and reliability. This ensures PWB applications (multilayer) that are most demanding. With mechanical and electrical properties matching high-frequency laminates exceptionally, the selection of a glass reinforced and non-reinforced adhesion materials and bonding gives designers the different alternatives for a complete ro4003 prepreg solution.

In addition, the development of countless bonding materials of ro4003 happens with different technologies. This results in different solutions.

Benefits of Ro4003 Prepreg

  • The thickness ranges between 0.0015 in and 0.005 in
  • The dissipation factor at a minimal 0.0009 at a dielectric constant of 2.99 at 10 GHz
  • This ro4003 prepreg is available without or with glass reinforcement

Comparing Rogers 4003 with other Roger PCB Series

A slight difference occurs between the Rogers 4003 and other Roger PCB series. This has to do with the parameters and performance.

Comparing the Rogers ro4003 to the Rogers 4350B, you will discover some little differences regarding performance, despite their close relation. The most striking of all comes from the UL 94V-0 flammability standard.

Rogers 4350 utilizes the technology for flame retardant, thereby getting the certification of UL 94V-0. This technology ensures its compliance with RoHS. However, the Rogers 4003 is not rated for UL 94V-0.

This burns anytime you expose it to temperatures that are too high. However, compared with the Roger 4350B PCB, the construction of the Rogers 4003 occurs making use of materials that are environmentally friendly. This material is also halogen-free.

Is Multilayer PCB possible with Rogers 4003?

Yes, it is possible to make a multilayer PCB using Rogers 4003. This depends on the requirements of your system. You can fabricate the multilayer PCB using pure laminates of Roger 4003, or have one as a hybrid, such as the Roger 4003 and the FR4.

This combination will yield a PCB with high performance, which is less expensive when compared to Roger 4003 PCBs with all layers. Make sure that the signal is placed on the core of the PCB, in contrast to doing so on top of the prepreg.
