Abstract This article introduces the correct connection methods for RS-485 networks, including twisted pair wiring and recommendations for proper installation of termination resistors. It lists the receiver waveforms under correct and incorrect termination. This application note provides a basic guide for connecting RS-485 networks. The RS-485 specification (officially known as TIA/EIA-485-A) does not specifically dictate … Read more
With the increasing popularity of high-speed Digital Signal Processors (DSPs) and their peripherals, electronic system designers are facing increasingly severe issues related to electromagnetic interference (EMI). In earlier studies, such issues were often referred to as electromagnetic interference (EMI) or radio frequency interference (RFI), while modern engineering more accurately adopts the concept of “electromagnetic compatibility … Read more
A good circuit board not only needs to achieve the functionality of the circuit design but also must consider electrical characteristics such as EMI, EMC, ESD (Electrostatic Discharge), and signal integrity. Additionally, mechanical structure and heat dissipation issues for high-power chips must be taken into account. On this basis, the aesthetic aspect of the circuit … Read more
Successful RF design requires careful attention to every step and detail throughout the design process. This means thorough and careful planning must be done at the start of the design phase, along with comprehensive and continuous evaluation of the progress of each design step. Such meticulous design skills are often lacking in the culture of … Read more
PCB grounding is a concern for PCB layout engineers, such as how to effectively plan a grounding system on the board, whether to wire analog, digital, and power grounds separately or together at a single point, and how to eliminate ground loops on the circuit board. Today, we will mainly discuss PCB grounding design, PCB … Read more
TOP Mounting Target On Paste Due to the ultra-thin and flexible characteristics of FPC (Flexible Printed Circuits), it is widely used in the sliding and bending parts of small electronic devices, as well as in the three-dimensional layout of small mobile terminals like smartphones and wearable devices. However, despite the widespread application of flexible circuit … Read more
In microcontroller systems, the issue of electromagnetic compatibility (EMC) is one of the most challenging to resolve. It primarily stems from electromagnetic interference (EMI) both inside and outside the system, which can easily lead to abnormal operation of the microcontroller, thereby affecting the stability and reliability of the entire system. Therefore, it is essential to … Read more
Search on WeChat Skill Training The Programmable Logic Controller (PLC) is a type of programmable memory used to store programs internally, execute logical operations, sequential control, timing, counting, and arithmetic operations based on user commands, and control various types of machinery or production processes through digital or analog input/output. Today, we have organized a comprehensive … Read more
