High-frequency PCB design is demanding and requires careful attention to every design detail. This is because the higher the frequency, the more sensitive the signal is to interference and losses. This article brings together high-frequency PCB design guidelines, from the type of materials used to the traces and stack-up or component layout. What is a high...
This article mainly focuses on the concepts and design principles of microwave-grade high-frequency circuits/microwave circuits and high-frequency PCB design in a cutting-edge field of communication products. The reason for choosing microwave-grade high-frequency circuits/microwave circuits and high-frequency PCB design principles is that this aspect of the principle has a wide range of guiding significance and is a high-tech...
In the field of modern electronics, circuit boards are used more and more widely. High-frequency PCB is one of the important types of circuit boards, which plays an important role in various research and industrial applications. So, what is a high-frequency PCB ? How do we understand this concept ? concept High-frequency PCB mainly refers to circuit boards that...
In modern multilayer PCB circuit board design, selecting the correct grounding method is essential for ensuring optimal signal integrity, minimizing electromagnetic interference (EMI), and maintaining stable power integrity. A well-designed grounding system not only improves overall PCB performance but also enhances the reliability of high-speed and high-frequency electronic applications. One of the most widely used...
With the rapid development of electronic technology and the widespread application of wireless communication technology in various fields, high frequency, high speed and high density have gradually become one of the significant development trends of modern electronic products. The high frequency and high speed digitalization of signal transmission force high-frequency PCBs to move towards micro-holes and buried/blind...
With the development of electronic information technology, multi-layer PCB circuit boards are used in more and more fields. Traditionally, we define PCBs with more than four layers as “multi-layer PCBs” and PCBs with more than ten layers as “high-layer PCBs”. Whether or not a PCB manufacturer can produce high-layer PCBs is an important indicator of its...

At present, high-frequency PCB and high-speed PCB design have become the mainstream, and every PCB Layout engineer should be proficient in it. Today, let’s talk about some design experience of hardware experts in high-frequency and high-speed PCB circuits, hoping to help everyone. 1. How to avoid high-frequency interference? The basic idea to avoid high-frequency interference is to minimize the interference...
Unlike standard printed circuit boards, flexible PCB circuit boards use flexible polymers instead of typical FR4 materials. The commonly deployed flexible polymers require a polyimide film substrate or a polyester substrate, which is a strong material that does not soften under heating and remains flexible when thermoset. A large number of thermosetting resins such as PI remain rigid...
When designing a multi-layer PCB, you need to pay attention to a basic situation, that is, how many wiring layers, ground planes, and power planes are needed to achieve the required functions of the circuit. The establishment of the number of wiring layers, ground planes, and power planes of the multi-layer PCB is related to the...
