What kind of PCB stacking strategy helps shield and suppress EMI?

Posted on July 19, 2018 by G

The following layered stacking scheme assumes that the supply current flows on a single layer, with single or multiple voltages distributed across different parts of the same layer. The case of multiple power planes is discussed later.

High Frequency PCB Routing Skills

Posted on July 19, 2018 by G

Digital devices are moving in the direction of high speed, low consumption, small size, and high anti-interference. This trend has put forward many new requirements for the design of printed circuit boards. The application of Protel software in China is quite common. However, many designers only pay attention to the Protel software's routing rate. The improvements made by Protel software to adapt to the changes of device characteristics are not used in the design, which not only makes software resources. The waste is more serious, and the excellent performance of many new devices is difficult to play. This paper intends to introduce Protel for Windows V1.5 software as an example to introduce the high-frequency circuit wiring when Protel software can Some special countermeasures are provided.

The importance of layout in high speed PCB design

Posted on July 10, 2018 by G

Throughout the successful electronic products, we must have five characteristics: one is stable in performance; two is beautiful in appearance; three is easy to apply; four is reasonable in cost; five is convenient for mass production; and it is not a successful product. These five points are related to the layout. In other words, a good and reasonable layout is to fully consider the above five points, so the layout is a very important part of the success of the product.

Seven Considerations in PCB Design

Posted on June 08, 2018 by G

The schematic design before single-panel proofing is a preliminary preparation work. When drawing a schematic diagram, it is necessary to pay attention to the final connection of each file as a whole in the hierarchical design. This also has important significance for the future work. Due to software differences, some software may appear to be physically connected (electrically). If you do not use related detection tools to detect, if something goes wrong, it will be too late to wait until the board is ready. Therefore, it is important to emphasize the importance of doing it in order, and we hope to draw everyone’s attention.

The core of PCB design and solutions

Posted on June 08, 2018 by G

The design of a printed circuit board (PCB) refers to the layout of the circuit through the design principle drawing to produce the circuit board at the lowest possible cost. In the past, this usually required expensive specialized tools to complete, but now, with the increasing popularity of free high-performance software tools, such as DesignSparkPCB, and design models, circuit board designers have greatly accelerated the design speed.

Techniques of PCB layout and processing defects

Posted on June 05, 2018 by G

As the PCB size requirements are getting smaller and smaller, device density requirements are getting higher and higher, and PCB design is becoming more and more difficult. How to achieve a high PCB layout rate and shorten the design time, careful analysis of the design and careful setup of the tool software before starting the wiring will make the design more in line with the requirements.

There are also two ways of layout, manual routing and automatic routing. PowerPCB provides manual routing capabilities that are powerful, including automatic push and online design rule checking (DRC). Automatic routing is performed by Specctra's cabling engine. Usually these two methods work together. The common steps are manual-auto-manual.

Posted on May 25, 2018 by G

There are indications that the frequency of PCB design is getting higher and higher. As the data rate continues to increase, the bandwidth required for data transfer also contributes to signal frequencies up to 1 GHz, or even higher. Although this high-frequency signal technology far exceeds the millimeter wave technology range (30GHz), it does involve RF and low-end microwave technologies.

1. Try to increase the distance (S) between parallel lines, at least greater than 3H, and H refers to the distance the signal is routed to the reference plane. The popular saying is to walk around the big bend. As long as S is big enough, it can almost completely avoid the mutual coupling effect.
