High-frequency boards are the basis for the realization of microstrip circuit engineering. In the process of microstrip circuit design, sometimes the original design boards are out of stock, or it is necessary to use more reliable high-frequency boards for circuit design. So how to solve the above problems simply, quickly and accurately based on the original...

Circuit materials rely on high-quality conductors and dielectric materials to connect modern complex components to each other for optimal performance. However, these PCB copper conductors, whether DC or millimeter wave (mmWave) PCB boards, need protection against aging and oxidation. This protection can be achieved in the form of electrolytic and immersion coatings. They usually provide different degrees of...

Millimeter wave (mmWave) applications have grown steadily over the past few years . This growth has also come from the semiconductor industry, which has been able to mass-produce chips with good mmWave performance. As mmWave applications increase, many aspects of the electronics industry, including the PCB industry, have had to enter a rapid learning process. In general, the...

Temperature characterization parameters of PCB circuit materials can provide insight into how temperature variations in the operating environment affect mmWave and high-speed digital (HSD) circuit performance. Material operating temperature is an often overlooked circuit material parameter. However, elevated operating temperatures caused by heat sources inside or outside the board can cause changes in circuit performance, especially at...

There are many ways to solve the EMI problem. Modern EMI suppression methods include: using EMI suppression coatings, selecting appropriate EMI suppression components and EMI simulation design, etc. This article starts with the most basic PCB layout and discusses the role and design techniques of PCB layer stacking in controlling EMI radiation. Power Bus Reasonably placing a...

In the past two or three years, the most fashionable technologies and products in our industry are HDI (high density interconnection) and Build-up Multilayer (build-up printed circuit board). However, in the development trend of market economy and high-tech products, there is another branch, which is high-frequency microwave printed circuit boards and metal-based printed circuit boards. Today, I will...

In this article, we will learn about the essential semiconductor manufacturing process.  I have already explained about uses of silicon in electronics, which is the main material used to make semiconductors. In order for silicon to turn into a semiconductor chip, it needs to go through the several complex process of wafer manufacturing, oxidation, photolithography, etching, deposition and...

Flex PCB Benefits There are some pretty amazing benefits to using flexible PCBs. Some of the advantages of flexible PCBs include the following: Reduced Space and Weight: Most of the advantages associated with flexible PCBs come from their low volume and weight. In fact, using a flexible PCB instead of a rigid PCB can result in a space reduction...
