Mark as Favorite Read Good Articles Daily As a PCB design engineer, it is essential to possess knowledge about high-speed signals. High-speed signals are typically found in various parallel buses and serial buses. Understanding what a bus is will help you determine its speed and start routing. Bus A bus is a shared physical pathway … Read more
With the emergence of high-speed DSP (Digital Signal Processors) and peripherals, new product designers face an increasingly severe threat from electromagnetic interference (EMI). Initially, the issues of transmission and interference were referred to as EMI or RFI (Radio Frequency Interference). Now, a more definitive term, “interference compatibility,” is used instead. Electromagnetic compatibility (EMC) encompasses both … Read more
With the rapid development of electronic technology, high-speed DSP systems have become core components in many fields. However, in practical applications, the complex electromagnetic compatibility environment and high-temperature conditions can severely impact system stability. Therefore, how can we effectively design the electromagnetic compatibility and heat dissipation of high-speed DSP systems? 1. Electromagnetic CompatibilityElectromagnetic compatibility is … Read more
As the working frequency of DSP continues to increase, the design of power and ground has become increasingly important in high-speed DSP systems. This also raises higher requirements for electronic engineers. A reasonable design of power and ground not only affects system performance but also directly impacts the stability and reliability of the system. Therefore, … Read more

In the process of learning electronics, we often encounter Printed Circuit Boards (PCBs) and Integrated Circuits (ICs). Many people find it hard to distinguish between these two concepts. In fact, they are not that complicated. Today, we will clarify the differences between PCBs and integrated circuits. What is PCB? PCB (Printed Circuit Board) is an … Read more
Click Blue Text Follow Us~ 1 Cutting (CUT) Cutting is the process of cutting the raw copper-clad board into pieces that can be made into boards on the production line. First, let’s understand a few concepts with the EDA365 Electronics Forum: (1) UNIT: A UNIT refers to the unit graphic designed by the PCB design … Read more
The development of modern electronic industry is changing rapidly, with large-scale and ultra-large-scale integrated circuits becoming increasingly complex. The traditional method of manually designing and manufacturing circuit boards can no longer meet production needs and is prone to errors. Here, I will introduce how to automatically convert schematics into PCB layouts. By relying on the … Read more
