How to solve EMI to improve the performance of multi-layer PCB

Posted on August 27, 2018 by G

In the design of power circuit, electromagnetic interference is one of the key factors affecting product performance. At present, there are many ways to solve the problem of EMI for engineers. Generally, methods for suppressing EMI include: EMI suppression coating, EMI simulation. Design and selection of suitable EMI suppression parts. This article will start with the PCB, and introduce the role and design skills of PCB layered stacking in controlling EMI radiation.

The core of PCB design - solving problems

Posted on August 27, 2018 by G

Conducting printed circuit board (PCB) design refers to the production of circuit boards at the lowest possible cost by designing schematic drawings and wiring layout. In the past, this usually required expensive tools, but now, with the availability of free high-performance software tools such as DesignSpark PCBs and design models, the speed of board designers has been greatly accelerated.

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.
