High Speed PCB Design Guide

Posted on August 10, 2018 by G

High-speed circuit design is a very complex design process. There are several factors that need to be considered when designing a high speed circuit. These factors are sometimes opposite each other. Such as the high-speed device layout when the position is close, although the delay can be reduced, but crosstalk and significant thermal effects may occur. Therefore, in the design, we must weigh the various factors and make a comprehensive compromise; not only meet the design requirements, but also reduce the design complexity. The adoption of high-speed PCB design means the controllability of the design process. Only controllable is reliable.

PCB Layout - High Speed PCB Design Guide

Posted on August 10, 2018 by G

In design, layout is an important part. The quality of the layout results will directly affect the effect of the wiring, so it can be considered that a reasonable layout is the first step in the success of PCB design.

PCB Routing - High Speed PCB Design Guide

Posted on August 10, 2018 by G

In the PCB design, wiring is an important step to complete the product design. It can be said that the previous preparation work is done for it. In the whole PCB, the wiring design process is the highest, the trick is the finest, and the workload is the largest. The PCB wiring has single-sided wiring, double-sided wiring, and multilayer wiring. There are two ways to route: automatic routing and interactive wiring. Before automatic routing, you can use interactive pre-wired lines that require more stringent requirements. The edges of the input and output should avoid adjacent parallel to avoid reflection interference. If necessary, ground wire should be isolated. The wiring of two adjacent layers should be perpendicular to each other, and parasitic coupling is easy to occur in parallel.

Power integrity design

Posted on October 24, 2025 by G

In circuit design, we are generally concerned about the quality of the signal, but sometimes we are often limited to the signal line for research, and the power and ground as the ideal situation to deal with, although this can simplify the problem, but in high-speed design This simplification is no longer feasible. Although the direct result of circuit design is manifested in signal integrity, we must not neglect the power integrity design. Because power integrity directly affects the signal integrity of the final PCB. Both power integrity and signal integrity are closely related, and in many cases, the main cause of signal distortion is the power system. For example, the ground bounce noise is too large, the design of the decoupling capacitor is not suitable, the loop effect is serious, the division of multiple power/ground planes is not good, the design of the ground layer is unreasonable, the current is not uniform, and the like.

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.

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.
