高频 PCB 是一种专门设计用于处理 1 GHz 及以上范围内的高频信号的 PCB。它由高频材料制成,用于许多需要快速、可靠、高效、低衰减信号传输且具有恒定电绝缘的设备。一般来说,高频 PCB 代表了现代通信技术的一个发展点,例如 5G、无线通信 (WIFI)、雷达系统、微波射频、卫星系统以及医疗和军事领域的其他高度先进的电子设备。
为了实现高频PCB板的这些优越特性,必须考虑一些必须表征高频PCB板设计的材料的因素。
低介电常数(DK): 它影响信号传输的速度和频率。 值越高越好,因为值越高可能会导致传输延迟。
绝缘子厚度: 绝缘体的厚度越薄,阻抗管理越好。
低损耗因子(Df): 它可以减少和防止信号损失并提高其传输质量。
热稳定性: 它可以保护电路板在高温工作时免受电阻抗变化的影响。
防潮及吸水性: 它可以防止面板电气性能的任何恶化,也有助于DK和Df的稳定性。
The high-frequency PCB market is vast and has many characteristics, making it one of the most popular types of PCBs. It has the following characteristics:
Heat resistance: High frequency PCB boards have strong heat resistance because they contain materials that help dissipate heat
High transmission speed: High transmission speed is an essential feature of all modern and advanced electronic devices.
Excellent signal management: fully controlled signal management, high transmission reliability, and low signal loss.
High Durability: These panels have very high durability, giving the product a good service life and high efficiency
Low cost: They are usually small in size, which greatly helps to save on the use of wires and thus helps to reduce costs.
When designing high-frequency PCBs, please consider the following points:
Material selection: Choose materials with good coefficients to meet product requirements, such as those with DK Df、 Thermal stability and good impedance to minimize losses in signal transmission. The most common materials are FR4, PTFE, PTFE, and Rogers materials.
Copper foil thickness: Pay attention to the thickness of the copper foil to ensure it has an appropriate thickness to prevent any loss of transmission signals.
Frequency requirements: Establish all basic requirements for designing high-frequency PCB circuits and specify the frequencies required to operate these circuits, while also specifying whether the circuit board uses a specific frequency or several different frequencies.
Safety: When designing, please consider the safety of the circuit board to prevent any interference or distortion of the signal. The method is to guide these frequency signals and strive to ensure the lowest level of crosstalk occurs.
Current return path: Maintain a good current return path, as signals in high-frequency PCBs require separate paths.
Through hole design: The design of through holes should pay attention to the small quantity to reduce interference with signals, ensure signal quality, and guarantee transmission speed. To reduce signal reflection, blind holes or buried holes must be used.
Quality testing: In order to ensure the integrity of the final design of the high-frequency board PCB, we use simulation tools to test the design and ensure that it works properly and effectively performs its functions. The simulation tool also analyzes and checks the signal transmission and its integrity against any electromagnetic interference (EMI) and electromagnetic compatibility (EMC).
Finally, you must be familiar with all modern advanced technologies and tools that help ensure the integrity of high-frequency PCB board design.
Given the precision required for high-frequency PCB design, we have found that all stages of manufacturing high-frequency PCBs must be carried out with unparalleled caution and precision, as they are naturally used as circuit boards for many devices and applications with sensitive and hazardous tasks, such as medical and military equipment. Therefore, the error rate in the manufacturing process of high-frequency PCB boards must be zero. When starting the manufacturing process of high-frequency PCB boards, please consider the following points.
The high-frequency PCB manufacturing process begins to ensure the integrity and reliability of the design scheme of the high-frequency PCB board you previously designed. You should conduct all tests on the design to ensure its suitability for manufacturing.
The design drawings are printed using a dedicated PCB printer. It is printed on the inner copper layer, which is connected to the substrate representing the PCB structure of the board. After completing the printing and engraving process on copper, the inner and outer layers will align perfectly and ensure that they are arranged correctly.
Install the inner and outer copper layers separately after plating, and collect the inner and outer layers.
After the layering process is completed, the drilling process begins, using drilling equipment such as X-ray machines to identify holes and then proceed with drilling.
After the etching process is completed, clean the circuit board and remove excess copper. Afterwards, the circuit board can be coated with chemicals specifically designed for PCB painting, which help to merge and bond the layers together.
Ensure again that the circuit board is completely clean before placing the solder mask layer on it. In order to protect the solder mask layer, copper, and all layers of the high-frequency PCB, screen screening and precision machining are required
The high-frequency PCB board is now ready for testing to ensure the performance of the circuit board, such as insulation testing, electrical performance of the circuit board, and other tests required to ensure smooth operation of the circuit board.
However, if a company cannot guarantee that all these considerations are met with high capability and efficiency, accurately and reliably executing all these stages, the likelihood of errors occurring during the manufacturing process will be high. Therefore, you must have confidence in who you are dealing with from the beginning to ensure the production of high-quality high-frequency PCB boards.
The high-frequency PCB industry now plays a very important role in the PCB industry, and we have found many companies competing in this market, committed to providing all modern and advanced technologies to produce high-frequency PCBs with high performance efficiency and reliability.
China is one of the countries with outstanding reputation and popularity in various fields of the PCB industry. Previously, the industry was dominated only by Europe and the United States, but now China has opened many doors for the supply and manufacturing of high-frequency PCB boards. China now offers high-quality, high-performance, and highly reliable high-frequency PCBs because it has many high-frequency PCB manufacturers that meet international standards, committed to providing the best materials and tools for the high-frequency PCB industry. Therefore, China is considered one of the most popular countries in the field of high-frequency PCB board manufacturing.
Common materials for high-frequency PCBs in China: The most commonly used basic materials for high-frequency PCB production in China are Rogers, Teflon, and FR4. This indicates that China has mastered the latest processes and skills required for efficient production of high-frequency PCB boards.
Application areas of high-frequency PCBs in China: We have also found that China provides many advanced systems in the high-frequency PCB industry, such as satellites, antennas, car phones, high-frequency communication, microwave transmission systems, and other modern systems.
With the rapid and continuous development of PCBs, we have increasingly high requirements for data transmission, signal transmission speed and stability, and the transmission of large amounts of data. All of this requires constant updates to satellite, microwave, fiber optic equipment, and other devices that rely on high-frequency PCBs.
