In PCB wiring, improper layout of ground and power lines will cause interference in the system, resulting in decreased line performance. Only by properly handling the ground and power lines and minimizing the interference noise they generate can the quality of PCB wiring be guaranteed. Ground and power line design

Copper coating is an important part of PCB design. Do you know it? The so-called copper coating is to use the idle space on the PCB as the reference surface and then fill it with solid copper. These copper areas are also called copper filling. The significance of copper coating

Wiring is the most important process in the entire PCB design, which will directly affect the performance of the PCB board. When engineers are doing PCB wiring, they must not only follow some principles, but also meet the process requirements of power lines, pads, vias, etc. Process requirements for PCB

Currently, high-frequency and high-speed PCB design has become the mainstream, and every PCB Layout engineer should be proficient in it. Next, 2PCB will share with you some design experience of hardware experts in high-frequency and high-speed PCB circuits, hoping to help you. 1. How to avoid high-frequency interference? The basic

Whether you are just learning PCB design or have become a PCB Layout engineer, Allegro software is a tool that everyone must master. Next, 2PCB will share some tips on using Allegro software with you, hoping to help you. Unit conversion 1mil = 0.0254 mm 1mm = 39.3701 mil By

In high-speed PCB design, differential signals are increasingly used, and the most critical signals in the circuit often have to be designed with differential structures. Why is this so? Compared with ordinary single-ended signal routing, differential signals have the advantages of strong anti-interference ability, effective EMI suppression, and precise timing

During the application of communication products, overvoltage and overcurrent caused by lightning strikes and other reasons will cause damage to the device ports, so corresponding protection circuits should be designed. Next, 2PCB will introduce the components in the lightning protection circuit and the requirements for the protection circuit in PCB

In order to reduce crosstalk between lines, the line spacing should be large enough. When the line center spacing is not less than 3 times the line width, 70% of the electric fields can be kept from interfering with each other, which is called the 3W rule. If you want

As an electronic person, the basic knowledge of digital circuits is something that everyone must master, and the same is true for electronic people who learn PCB design. Today, 2PCB mainly introduces the combinational logic circuits in digital circuits. About combinational logic circuits The circuit that uses digital signals to

In all the processes of PCB design, wiring is the most delicate, most restrictive, and most time-consuming. Many engineers spend their daily work “drawing wires” diligently. Next, 2PCB will share some very practical wiring tips with you, hoping to be helpful to you. Wiring tips between power and ground wires

Layout means placing the components on the board reasonably based on comprehensive consideration of signal quality, EMC, thermal design, DFM, DFT, structure, safety regulations and other requirements. In high-speed PCB design, reasonable layout is the first step to successful PCB design. Next, 2PCB will introduce the ideas and principles of

Signal integrity (SI) refers to the quality of the signal on the transmission path. With the increase in the output switching speed of integrated circuits and the increase in the density of PCB boards, signal integrity has become one of the issues that must be concerned about in high-speed digital
