We are here to teach you everything necessary regarding the Rogers 4003C. These include its properties, features, benefits, applications, and more.

Therefore, before going ahead to purchase these PCB materials from Rogers, take your time to read this guide.

Rogers 4003C: What is this High-Frequency Material?

The Roger 4003C material has to do with woven glass that is patented and reinforced hydrocarbon/ceramics that has the electrical performance of woven glass/PTFE and the manufacturability of glass/epoxy.

It is supplied in different configurations, with its laminates using both 1080 and 1674 styles of glass fabric. Also, all the configurations deliver similar requirements of electrical performance.

The dielectric constant of the laminates of the roger 4003c is tight. Also, it offers low loss and uses a processing technique that is similar to the conventional glass/epoxy

Also, they don’t require unique handling processes or thru-hole treatments. This makes them different in contrast to the high-frequency materials that are PTFE based.

Factors You Need To Consider When Choosing the Roger 4003C Laminate

Generally, there is a need to check these issues before you choose a high-frequency laminate when designing. This will help to reduce the cycle time for the design.

These factors include:

  • Cost
  • Electrical and mechanical thermal stability
  • Dielectric constant
  • Material loss

Also, several materials are suitable for PCB applications requiring high frequency. However, Roger 4003c offers the best, when it comes to cost and performance.

Several materials are suitable for PCB applications of high frequency. However, the Roger 4003c offers the best when it comes to cost and performance.

Furthermore, it offers great control of dielectric constant. It is also low, which is important for any C-band frequencies and beyond.

However, the Roger 4003c doesn’t just offer the right electrical properties. It is also possible for you to fabricate it by the application of glass epoxy procedures. This reduces costs for fabrication.

In general, this laminate helps in blending the highest electrical characteristics. It also offers construction ease at a price that is competitive for any commercial application.

Major Circuit Technologies Utilized in the Rogers 4003C Substrates

In order to achieve optimum performance, the Roger 4003C laminate can make use of either the microstrip circuitry technology or grounded coplanar waveguide.

Each two circuit technology to serve high-frequency printed circuit boards has its own disadvantages and advantages, which will be explained below.

Grounded Coplanar Waveguide Circuits

This is also called the coplanar waveguide that is conductor-backed, this circuit technology raises the amount of ground about a specific circuit in contrast to microstrip.

It achieves this by placing the ground planes in the Rogers 4003c dielectric material’s base. Also, the ground planes can be placed on any of the sides, on the same plane, and on the top area of the transmission line of the signal

The circuitry structure of the GCPW gets electrical stability by making use of ground planes in surrounding a specific signal line. Both the circuit technologies of the Roger 4003c substrate, functions by a means known as quasi-transverse-electromagnetic propagation.

Microstrip Circuits

This circuit has to do with thin lines of transmission that are seen on one of the laminate’s edges and a metal ground plane that is conductive and found on any of the other edges.

Several parameters related to materials affect the microstrip transmission line’s performance, which includes

  • The thickness of the dielectric material
  • The conductive metal’s roughness and smoothness at the interface of the copper substrate
  • Thickness of the conductive metal

Properties you should consider when Choosing a Solder Mask For your Roger 4003c Laminate

There are several characteristics you have to consider whenever you are choosing a solder mask to use for your Roger 4003C RF/Microwave circuits. These include:

  • Great heat resistance
  • Electrical insulation must be high
  • High adhesion
  • Plating resistance to different plating kinds must be great
  • Compliance with specifications that are halogen-free
  • Its shelf life must be long

For Rogers 4003c laminates application where the performance becomes significant, the color choice of your solder mask can affect the Df and Dk of your material.

Also, a difference in color could imply. Though it may be negligible, both parameters must show a difference.

Proper preparation of the PCB surface and cleaning can help as well to achieve strong bonding of the solder mask to the laminate’s surface when you apply them.

What Quality and Safety Standards Exists for the Rogers 4003C Laminates?

Below are the quality and safety standards that are recognized internationally. You should look out for these in your Roger 4003c materials.

  • UL standards
  • IPC standards
  • RoHS Standards
  • ASTM Standard
  • CE Standard
  • ISO Standard
  • ANSU standard

When Do You Need Controlled Impedance in Roger 4003C Laminate?

Employing controlled impedance when a signal has to possess a particular impedance to help it function properly. The matching impedance of the trace of the Roger 4003C substrate in PCB applications requiring high frequency are important in maintaining data integrity and signal sharpness.

This is very important to make sure that the laminate trace’s impedance that links the two components matches the component’s characteristic impedance.

Any mismatches of the impedance e has the ability to increase the switching times in Roger 4003C printed circuit board or devices, coupled with random errors.


Depending on the application requirements that suits you, RayMing PCB offers different Rogers PCB laminates, including the Rogers 4003c laminates.
