Differential signal VS single-ended signal Single-ended signal Single-ended signal is a simple and common way to transmit electrical signals from a transmitter to a receiver. Electrical signals are transmitted through voltage (usually a changing voltage) that is based on a fixed potential, usually a 0V node called “ground”. Differential signal

On the basis of comprehensive consideration of signal quality, EMC, thermal design, DFM, DFT, structure, safety regulations and other requirements, the components are reasonably placed on the board. ——PCB layout Except for special requirements, all component pad routing must meet thermal design requirements. ——General principles of PCB routing It can

PCB device layout is not a matter of arbitrariness. It has certain rules that everyone needs to follow. In addition to general requirements, some special devices will also have different layout requirements. Layout requirements for crimping devices 1) There shall be no components higher than 3mm around the surface of

As an excellent PCB design engineer, you need to master some necessary design concepts so that you can design a better board. Today, let’s learn about the “three properties” of standard PCB: manufacturability, testability, and reliability. Manufacturability of PCB Design for manufacturability (DFM) takes manufacturability and testability into consideration from

In PCB silk screen design, it mainly includes: component silk screen, board name, version number, barcode silk screen, mounting hole positioning hole silk screen, board direction mark, anti-static mark, positioning identification point, etc. Today, we mainly learn about the requirements for component silk screen design. General requirements for silk screen

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
