If you are employing PCBs for any application involving space technology, mobile networking, or microwaves, then Rogers PCB materials will provide superior performance in comparison to any other PCB materials. Although the price of Rogers PCBs is more than the price of other PCBs, the fact that they function better and have additional capabilities makes them less expensive than the competition. Therefore, Rogers printed circuit boards materials are superior to any other type of PCB. Because of their superior functionality and dependability, several companies and organizations across a variety of sectors favor Rogers PCBs. This preference is widespread. Therefore, while choosing PCB for your project, it is necessary to have an understanding of the ways in why it is superior to Rogers.
There are various varieties of Rogers PCB substrates that each have unique qualities and features. As a result, selecting the best substate material among the numerous options becomes a difficult process for many. Making the best decision requires careful consideration of several things. Here are a handful of them.
3. Factors to Consider when choosing a Rogers Material
Even while knowledgeable Rogers PCB manufacturers may advise you on the best Rogers materials, it’s still crucial to understand your application’s needs. In addition to this, consider the following variables when selecting the appropriate Rogers material:
- Coefficient of thermal expansion
It is common knowledge that most substances will grow larger if there is a rise in the temperature of the substance, and the opposite is also true. Therefore, the same thing also occurs with the material used in PCBs; it likewise relaxes and expands because of being exposed to high temperatures or reducing temperatures, respectively. In most cases, a temperature limit, which is often referred to as the glass transition temperature, will determine when the expansion will take place. Below the transition temperature, PCB material does not expand, but as the temperature rises beyond the threshold level, expansion will commence. The performance and quality of the material will improve in direct proportion to the glass transition temperature. The greater the material’s coefficient of thermal expansion, the greater its resistance to change in shape under the influence of temperature. Therefore, the coefficient of thermal expansion has a relationship with the deformation. The lower the value of CTE, the earlier the deformation will begin, and the material will not be suitable for use at high temperature because it will deform, which could lead to a malfunction or affect the result. The unit of deformation is in parts per million, also known as ppm (ppm).
A primary benefit of Rogers’s material is that it reduces the pressures that might lead to an unintentional change in the physical form of PCB board. This is one of the reasons why such a material is advantageous. Because these types of boards have a value glass transition temperature that is virtually close to 280 degrees Celsius (536 degrees Fahrenheit), its expansion properties are able to remain consistent across the complete range of temperatures that are used in circuit processing. Therefore, Roger 4000 is the ideal option for you if your project is sensitive to temperature and if it is possible for a change in temperature to cause it to malfunction or interrupt the results.
- Dielectric Constant
The capacity of a substance to hold an electric charge is referred to as its dielectric constant or its relative permittivity. If a material has a high value of dielectric constant, then it will also have a high capacitance value. This will result in a higher number of charges being stored in the material, which will cause a high voltage to appear across the PCB. The dielectric value is present throughout a wide frequency range, which is one of the reasons why it can function more effectively in broad band applications. When selecting a material for a high frequency circuit board, one is necessary to take several things into consideration, including cost and performance. When sorting through PCB materials, the dielectric constant Dk is typically used as a primary starting point. The dielectric constant Dk is one of the required characteristics of a laminate material and is one that is subject to many comparisons among various suppliers of PCB materials.
When compared to other PCB materials, Rogers 3003, RT 5880, and RT 5870 provide the highest performance for applications requiring high frequency, high speed performance in wired and wireless communication, and noise sensitivity. Below is a table detailing the operating frequency range and dielectric constant of each material, making it easy for designers to choose the optimal material for their needs.
- Moisture Absorption
PCB materials should not be able to take in moisture from the environment under situations that are not realistically conceivable. Rogers PCB like any other element absorbs moister. Many of today’s PCB materials have values that fall somewhere in the range of 0.01 to 0.2 percent for their moisture absorption rates. Therefore, the material that makes up PCBs needs to have a low hygroscopicity. If the material’s absorption rate is larger, then it will have a greater effect on both its thermal and electrical characteristics.
The Rogers PCB has a lower moisture absorption rate compared to traditional PCBs, which results in improved electrical as well as thermal properties. As a result, it may be put to use in any and all circumstances and settings without suffering any degradation in its overall performance. In addition to this benefit, the likelihood of failure for such PCBs is lower. The Rogers 4350b’s theoretical values are quite close to being equivalent to 0.06.
- Decomposition Temperature
A PCB’s maximum and minimum operating temperatures should be determined depending on the application and designed using the appropriate materials. The project scope specifies the operational temperature range that must be met by the PCB board material for an application. A Rogers printed circuit board material should be chosen by the designer of the product if the electrical components of the product are susceptible to higher temperatures. The PCB must incorporate a mechanism that can reverse such deviations in case the temperature increases over a particular threshold that is considered acceptable. If temperature difficulties are not taken into mind, then anything that operates outside of its optimal temperature range will experience a loss of mass and eventually deteriorate over time.
Most of the applications need for a reliable temperature range that may go up to 350 degrees Celsius. Because certain Rogers’ materials have a higher temperature at which they decompose in comparison to the usual PCB materials, the designer ought to choose this material for a variety of applications.
4. Advantages Of Rogers PCB

6. Improved Thermal Capability
There are instances when the environment will be hostile, and PCB may not be able to endure in that setting. In the case of Rogers PCB, they can withstand heat. Yes, the PCB is unaffected by the warm atmosphere, and it can withstand temperatures of up to 350 degrees. You may therefore imagine how resistant to heat this dependable PCB is. The device in which Rogers PCB is put will continue to function without being impacted by the temperature increase. Rogers PCB is thus one of the better solutions for places with tough conditions.
