The design of PCB boards for stable working of switching power supplies now summarizes seven tricks: by analyzing the matters that need to be paid attention to in each step, you can easily design the PCB board step by step! 1.Design process from schematic diagram to PCB Establish component parameters-》Enter principle netlist-》Design parameter setting-》Manual layout-》Manual…

Designing and building the next generation of electronic products is a complex process, especially in a highly competitive global industry like the electronics industry, where rapid and continuous technological changes have become a common occurrence and the rule of innovation. If designers cannot accept these changes, they will face the risk of being left behind…

The 20H principle refers to the power layer being retracted 20H relative to the ground layer. H represents the distance between the power layer and the ground layer, and of course it is also to suppress the edge radiation effect. Electromagnetic interference will be radiated outward at the edge of the board – the power…

This article lists various design oversights, explores why each misstep can cause circuit failure, and gives suggestions on how to avoid these design flaws. This article uses a two-layer PCB with FR-4 dielectric and 0.0625in thickness as an example, with the bottom layer of the board grounded. The operating frequency is between 315MHz and 915MHz…

This paper discusses the overview and development prospects of fault diagnosis technology for electronic equipment circuit boards. Combined with the HTEDS8000 electronic equipment circuit board repair test and diagnosis system, a series of products of the “Hua Tuo Electronic Clinic” of the Aerospace Measurement and Control Company, this paper introduces circuit board fault diagnosis technology…

Many special characteristics of RF circuit are difficult to explain in a few short sentences, and cannot be analyzed using traditional simulation software, such as SPICE. However, there are some EDA software on the market that have complex algorithms such as harmonic balance and shooting method, which can simulate RF circuits quickly and accurately. But…

This article interprets the four basic characteristics of RF circuits from four aspects: RF interface, small desired signal, large interference signal, and interference from adjacent channels, and gives important factors that need special attention in the PCB design process. RF interface of RF circuit simulation Transmitters have two main PCB design goals: First, they must…

Characteristics of RF interface and RF circuit in PCB design Many special characteristics of RF circuit are difficult to explain in a few short sentences, and cannot be analyzed using traditional simulation software, such as SPICE.

Previously, we explained the principles and some details that need to be paid attention to in the design of the microcontroller control board. (” rel=”nofollow” target=”_blank”>See details)The design of electromagnetic interference mentioned in this article mainly deals with hardware and software. The following is an introduction to the processing of electromagnetic compatibility from the PCB…

As PCB high-speed signal design becomes more and more common, the design of electronic circuits faces more and more challenges such as signal integrity, power integrity, heat, and electromagnetic compatibility. Introducing simulation verification methods in design will greatly improve product development efficiency, design correctness, and achieve the fastest product launch to market. MentorGraphic’s HyperLynx software…

Practical experience and skills of PCB package drawings of electronic devices How to design PCB package drawings of electronic devices? What practical experience and skills are there? I often ask myself this question. As an electronics fan who has worked for more than 10 years and has drawn at least hundreds of PCB boards, I…
