How to reduce electromagnetic interference in automotive application analog devices

In the fields of medical equipment, automotive instrumentation, and industrial control, when equipment design involves strain gauges, sensor interfaces, and current monitoring, precision analog front-end amplifiers are often required to extract and amplif

Fiber optic sensor types, features and product introduction

The fiber optic sensor consists of a light source, an incident fiber, an exit fiber, a light modulator, a photodetector, and a demodulator. The basic principle is that the light of the light source is sent to the modulation area through the incident optic

Analysis of wiring rules for PCB traces

General wiring rules:1. Draw wiring area, within ≤1mm from the edge of the PCB board, and within 1mm around the mounting hole, wiring is prohibited.2. The power cord should be as wide as possible, should not be lower than 18mil, the signal line width s

Analysis of Five Basic Principles of PCB Design

1. Have a reasonable directionSuch as input / output, AC / DC, strong / weak signals, high frequency / low frequency, high pressure / low voltage. Their orientation should be linear (or separate) and should not be intertwined. Its purpose is to prevent mu

Discussion on Design Scheme of LED Switching Power Supply System for PCB Board

The development speed of LED switching power supplies has made a significant leap in recent years, and the speed of new product replacement has also accelerated. As the last design step, PCB design is also very important, because once there is a problem i

PCB process requirements and notes

In the PCB copy board, PCB design, and finally the mass production of PCB, PCB board is also a very important thing, which not only involves the quality standards of PCB circuit board, but also affects the cost of PCB production.How to save the raw materi

How to avoid distortion when designing high frequency PCB layout

In fact, printed circuit boards (PCBs) are made of electrically linear materials, ie their impedance should be constant. So why does the PCB introduce nonlinearity into the signal? The answer is that the PCB layout is space-non-linear relative to where th

Analysis of various electrostatic shielding techniques in electromagnetic fields

The shielding of electric fields, magnetic fields and electromagnetic fields is actually different!The shielding problem of magnetic field is a problem with practical significance and theoretical significance. According to different conditions, the shield

Analysis of the basic concepts of EMC simulation design

As product complexity and density increase and design cycles continue to shrink, it becomes increasingly impractical to address electromagnetic compatibility (EMC) issues later in the design cycle. At higher frequencies, the rules of thumb that you usuall

Introduction to the characteristics of five common sensors

Sensors are like the "five features" of equipment. They are the "must have" devices for human-machine communication. Sensors are generally composed of four components: sensitive components, conversion components, conversion circuits and auxiliary power su

Introduction to assembly technology of electronic component circuit boards

Electronic components are the cells of electronic information devices, and board-level circuit assembly technology is the basis for manufacturing electronic devices. The emergence of different types of electronic components has always led to a revolution

How to solve mutual interference problems in high speed PCB design

At present, most hardware engineers only design PCBs based on experience. During the debugging process, many signal lines or chip pins that need to be observed are buried in the middle layer of the PCB, and cannot be detected by tools such as an oscillosc
