The Features of the Rogers ro4003 PCB

The Rogers ro4003 PCB is a printed circuit board that is fabricated with the use of woven glass. It is also reinforced with hydrocarbon/ceramics.

The Rogers ro4003 PCB has the following main features

  • Its electrical properties are stable
  • Very low dielectric loss and tolerance. This makes it great for applications that demand high-frequency performance
  • Low expansion of the Z-axis
  • Low in-plane coefficient of expansion
  • Dimensional stability is great
  • Its temperature of glass transition is high
  • Manufacturing in very large quantities is possible
  • The dielectric constant’s thermal coefficient is low

Rogers ro4003 PCB vs Isola PCB: What’s the Difference?

Both the Isola PCB and Rogers ro4003 PCB are designed to be useful for high-performance and high-frequency applications.

The fabrication of Isola PCB is done making use of prepregs and copper clad laminates. The construction of the Rogers ro4003 PCB on the other hand is done with the use of woven glass, which has been reinforced with the use of ceramics/hydrocarbons.

However, both of them are useful for performance sensitive, high-volume performance and high-end consumer applications.

Rogers ro4003 PCB vs Taconic PCB: What’s the Difference?

The major difference between the Rogers ro4003 and Taconic PCB is their construction material. The fabrication of the Taconic PCB is done from fabrics and laminates that are made from coated silicone and PTFE.

The construction of the Rogers ro4003 is done with the use of woven glass. This glass is usually already reinforced with hydrocarbons or ceramics.

The fact is that both the Rogers ro4003 and Taconic PCB serve high-performance applications. Both of them are characterized by thermal stability, low dielectric constant, and low Z-axis.

Application of the Rogers RO4003 PCB

The Rogers RO4003 is useful in many applications, which requires high-performance and high-frequency printed circuit boards. Some of these uses include:

  • Analogue transmitter
  • RF modules
  • RF identification tags
  • Spread spectrum’s communication systems
  • LNBs construction to be used in broadcast satellites
  • Power antennas and amplifiers in microstrip and cellular base stations
  • Radar and sensors for automobiles etc.

Rogers RO4003 Dielectric Constant

A printed circuit board’s dielectric material is that material that serves as the PCB’s insulating layer. Also, it should have a low electric conductivity. Furthermore, these materials may be plastic, porcelain, mica, glass, or metal oxides.

Just like other Roger printed circuit boards, the Rogers RO4003 PCB features a dielectric constant that is low. This is due to the material used for construction has a tight and strong control over and low loss on the dielectric constant.

Materials having a dielectric constant that is low will lose little heat energy. Therefore, it becomes the most effective. A Rogers RO4003’s dielectric constant is divided to design and process dielectric constant. The design type is the one most useful during PCB construction. The process dielectric constant is 3.38 +/- 0.05. The design dielectric constant is 3.55 +/- 0.05.

It is less likely for the Rogers RO4003 to suffer dielectric breakdown. This breakdown occurs whenever the material begins to conduct current due to the strong electrostatic field. This is happening due to a voltage surge across it.

Rogers RO4003: Benefits

There are lots of benefits to enjoy by using the high frequency and high-quality Rogers RO4003. These benefits include:

  • Competitive and optimized costs
  • No need for through-hole or special handling in contrast to the PTFT-based printed circuit boards
  • Great for the fabrication of multilayer boards
  • Great for very demanding, performance sensitive, and high-volume application
  • Compatible with materials and processes such as FR-4 that reduces the production cost
  • Make use of lead-free and robust techniques for solder processing
  • Useful for the fabrication of hybrids of any mixed multilayers and dielectrics
  • High production
  • Its plated through holes are reliable
  • Useful for temperature-sensitive applications
  • Improvements bin thermal management due to high thermal conductivity

Does the Rogers RO4003 Have Any Limitations?

Though the Rogers RO4003 offers a great performance, it also comes with some limitations. Some of its notable downsides include the following.

Since the construction of the PCB is done with the use of materials that are hydrocarbon-based, it can easily experience changes in its dielectric properties whenever it is exposed to environments that are oxidative for very long periods.

Also, Roger PCB lacks materials that are flame-retardant. Furthermore, they burn easily when transportation is done at an extremely low speed.

Rogers RO4003: Standard Specifications

Some of the standard specifications of the Rogers RO4003 include the following:

  • 79 gm/cm3 material density
  • Transitional temperature above 280C DSC
  • Dielectric constant is low at 3.38 +/- 0.05
  • CTE (coefficient of thermal expansion) along the Z, Y, and X coordinates are 46, 14, 11 ppm/C respectively.
  • Its tensile strength is 141 MPa or 20.4 Kpsi
  • Dissipation factor is 0.0021 and 0.0027
  • +40 ppm/C as its thermal coefficient
  • Its transitional temperature above 280C DSC
  • Its dimensional stability is below 0.3 mils/inch

Conclusion

The Rogers RO4003 is one with a lot of excellent features. Though it comes with lots of benefits, there are a few limitations. However, the Rogers RO4003 PCB is one that will serve you as expected.
