High Frequency mmWave PCBA for 5G
Since the rise of 5G applications, mmWave PCBA applications have rapidly developed in various commercial markets, such as automotive radar, autonomous vehicles, body scanners, and satellite communications. But mmWave circuits are more difficult to design than other RF circuits, and in order for these applications to be successful, we have to consider circuit materials when designing PCBAs for mmWave frequencies. FS Technology will introduce the comprehensive content of 5G mmWave PCBA in detail below.
Detailed introduction of mmWave PCBA
mmWave is short for millimeter wave. We usually refer to the type of PCBA which is integrated with the mmWave is known as mmWave PCBA. Currently, during manufacturing, the high-frequency board manufacturer faces difficulty with 5G integration. So, mmWave PCBA is the finest option for high-frequency applications.
There is a need of new imaging techniques and metrology for the creation of mmWave PCBA. There are numerous manufacturing technologies that provide imaging features for the creation of complicated and high-quality PCBs for fifth generation. mmWaves provided the electromagnetic waves that have smaller wavelengths, so high frequencies produces through mmWaves. The High-frequency feature of mmWave PCBA helps to use them in telecom systems. Through use of high frequency, larger data can be transported at high speed. The device that is integrated with the mmWave PCBA has the ability to provide a speed of about four to five Gbps. With that, mmWaves also offered a faster speed than the fiber connections. These features help mmWave PCBA to be used for applications where high-speed data transmission with a high frequency is needed. mmWave PCBA can handle more users than other boards.
There is an old saying in China called “No one is perfect”, and this sentence also applies to mmWave PCBA, especially in terms of temperature. Temperature changes will inevitably lead to changes in mmWave PCBA performance. The temperature mentioned here includes the temperature on all circuit boards, whether caused by the current flowing through the PCBA or caused by the ambient temperature. All in all, the performance of a PCBA is directly related to temperature. With the continuous upgrading of PCBA manufacturing technology, different types of PCBAs have gradually emerged, including IMS PCBA (insulated metal substrate) dedicated to high temperature environments. Engineers need to pay more attention to the characteristics of materials when selecting materials for high-frequency applications. For the characteristics of millimeter-wave PCBA materials, FS Technology will only briefly describe in this article.
Material properties closely related to mmWave circuit performance include: dielectric constant, dissipation factor, moisture absorption, thickness tolerance, and of course, the roughness of the copper surface of the circuit board, which is most easily overlooked by PCBA designers. Fortunately, circuit material properties provide circuit designers with a way to understand the dielectric constant of a material in terms of the thermal coefficient of permittivity, which is the difference between Dk and nominal as a function of temperature.
Contribution of mmWave PCBA to 5G
mmWave is the key to enabling 5G with high transmission rates. The band of spectra that have wavelengths ranging from 30 GHz to 300GHZ is called mmWave. 5G technology is at starting phase and every type of industry has made some measures to handle and practical use of this technology. 5G is more advanced than the net we use. Through the use of this technology, we get can more advancements in technologies that are used in our PCs in near future will be in our hands. The combination of mmWave PCBA and 5G provides the following advantages for 5G technology:
mmWave technology is the key to 5G high-speed transmission
Millimeter waves PCBA are considered an integral part of 5G systems, and their operational operations are regulated by millimeter waves. As mentioned above, the mmWave frequency range is 30-300GHz, and the bandwidth is as high as 273.5GHz. Under this premise, even if it is affected by the atmosphere, the total bandwidth of the four windows can reach 135GHz. In the transmission of wireless signals, we have two ways to increase its speed: increase the spectrum utilization rate or increase the spectrum bandwidth. 5G mmWave uses increased spectrum bandwidth to increase its transmission speed.
High bandwidth provided by the mm-wave frequency causes increasing in rate speed. The transmission of data is like the product transfer between two points. Suppose that products transferred are data and distance between two points is electromagnetic waves. To transfer more products, there must we have more lanes at roads to move more vehicles having products. Like this bandwidth transfer larger data between two devices. Also, high bandwidth provides high-speed data transmission.
mmWave PCBA improves signal transmission accuracy
When 5G technology was first formed, signals were transmitted around, and this inaccurate signal transmission method caused a lot of waste of resources. In later applications, this problem is solved through millimeter wave and Massive MIMO technology. Millimeter waves have the characteristics of narrow beams, which enable them to more accurately distinguish dense targets and transmit signals more accurately. The application of 5G mmWave PCBA improves the accuracy of signal transmission.
Comprehensively provide the security index of 5G signals
When 5G signals are transmitted in the air, they will be affected by the natural environment. Even the micro-substances such as oxygen, water vapor, and suspended particulate matter will damage the security of signal transmission. Therefore, adding millimeter wave technology to 5G applications plays a great role in reducing the interference of signals between different terminals. But the drawback of millimeter wave PCBA for 5G is that it handles only indoor and outdoor areas one at a time. It indicates if we install an antenna outdoors will not send 5G signals to indoor connections.
5G systems are dominated by the mmWave PCB which enhances the compatibility of 5G. The use of millimeter waves with 5G helps the fifth generation to employ heavy data circuits and projects. This feature also provides such bandwidth that can handle the connected device easily. These features are also used for different projects such as education systems, control of traffic signals, and operation of different vehicles.
High frequency millimeter wave PCBA is more economical
5G is a new technological feat for cellular systems. With the integration of millimeter waves PCBA, 5G has different less expensive data plans with unlimited bandwidth. Different types of services can be provided by the use of millimeter waves through 5G, so it is an ideal option for different mobile companies to use this technology with 5G. The use of 5G PCBA not only provides the best services to users, but service providers also have high profits and their business grows. These benefits help to introduce new opportunities for operators. If we say, millimeter waves completed the fifth generation that enhances the network efficiency and helps to find the feedback of users’ experience about this feature.
Improve access to High-level resources
The reason the 5G signal can be high-speed and not stuck, thanks to the high-frequency PCBA, allows it to obtain more resources. The use of electromagnetic wave frequency is increasing in wireless communication for different generations. Therefore, in order to provide good services for video streaming and monitoring, it is necessary to rely on mmWave PCBs to obtain more frequency resources.
