Introduction Home automation has revolutionized modern living by integrating technology into everyday household functions. From lighting and climate control to security and entertainment, automation enhances convenience, energy efficiency, and security. One of the most exciting aspects of home automation is the ability to design and build custom solutions using Printed Circuit Boards (PCBs). Open-source PCB…
Abstract This paper presents a comprehensive guide to designing a motion-activated lighting system using printed circuit board (PCB) technology. The article covers the fundamental principles of motion detection, circuit design considerations, PCB layout techniques, and implementation strategies for creating an efficient and reliable motion-sensing light. By integrating passive infrared (PIR) sensors with microcontroller-based processing and…
In basic PCB design, it is easy to ignore the most familiar and simplest places, which leads to errors. This may cause problems or completely break down the perfect PCB circuit diagram when it is converted into a PCB board. Therefore, in order to assist engineers in reducing design changes and improving work efficiency in…
Join the exchange group During the circuit design process, application engineers often overlook the layout of the printed circuit board (PCB). A common problem is that the circuit schematic is correct, but it does not work, or only operates at low performance. I will show you how to properly layout the circuit board of an…
HDI board (High Density Interconnector), that is, high-density interconnection board, is a circuit board with a relatively high line distribution density using micro blind buried hole technology. HDI board has inner and outer layers of lines, and then uses drilling, in-hole metallization and other processes to connect the internal layers of each layer of lines….
Today I will share with you: decoupling capacitor, decoupling capacitor PCB design and layout. 1.Decoupling capacitor Decoupling capacitor is used to filter out the interference of output signal. It is usually used in amplifier circuits that do not require AC power to eliminate self-excitation and make the amplifier work at a low temperature. In a…
The water vapor film on the uncoated printed circuit board also provides favorable conditions for the growth and corrosion of the metal. Other common adverse effects include reducing the dielectric strength of the medium and affecting high-frequency signals. What kind of coating material does the PCB manufacturer use? What are the precautions? Dust, stains and…
Sometimes, the distinction between what is considered a “slow” or “fast” signal can seem arbitrary and can depend on who you ask. A related topic is whether a PCB trace is electrically “short” or “long,” and you’ll likely find just as much disagreement on that topic. Whether you need to route slow or fast signals…
Introduction Printed Circuit Board (PCB) etching is a critical process in electronics manufacturing, where unwanted copper is removed from the board to create conductive pathways. Proper maintenance of PCB etching equipment ensures consistent quality, prolongs machine lifespan, and reduces production downtime. This article provides a comprehensive guide on maintaining PCB etching equipment, covering cleaning procedures,…
Introduction Time-lapse photography is a fascinating technique that captures a series of images at set intervals and combines them into a video, creating the illusion of time moving quickly. To achieve this, photographers rely on an intervalometer, a device that triggers the camera shutter at predefined intervals. While commercial intervalometers are widely available, building a…
Next, we will introduce how to improve the routing rate of PCB wiring design. In PCB wiring design, there is a complete set of methods to improve the routing rate of PCB design. Here, we provide effective techniques to improve the routing rate and design efficiency of PCB design, which can not only save customers…
With the decrease of signal rise time and the increase of signal frequency, the EMI problem of electronic products has been paid more and more attention by electronic engineers. The success of high-speed PCB design has made more and more attention to the contribution of EMI. Almost 60% of EMI problems can be controlled and…
I believe that when you are designing PCB, you will find that wiring is indispensable, and the rationality of wiring also determines the aesthetics of PCB and the production cost. At the same time, it can also reflect the circuit performance and heat dissipation performance, as well as whether the performance of the device can…
Too many vias on PCB is a common problem in electronic design, which may be caused by many factors, such as unreasonable design, complex routing, signal requirements, etc. To solve the problem of too many vias on PCB, we need to start from multiple aspects such as design, layout, routing and communication with manufacturers. I….
