Introduction The proper operation of modern electronic systems relies fundamentally on power supply technology. As the cornerstone of all electronic designs, power supply circuits require precise understanding of their terminology as a prerequisite for developing functional projects. Standard terms such as VCC, VEE, VDD, and VSS are ubiquitous in IC Read more
Introduction Light is one of the fundamental needs of human life, and our world is filled with a vast array of light sources, ranging from the soft glow of a bedside lamp to the intense illumination of a stadium. The intensity of light varies depending on its type, power consumption, Read more
In the world of custom mechanical keyboards, we often talk about switches, keycaps, and case feel. However, hidden beneath all these components lies the true core that determines a keyboard’s functionality, reliability, and customizability: a green circuit board—the PCB. This article provides an in-depth yet accessible analysis of every aspect Read more
What is an Aluminum PCB? An Aluminum PCB, also known as a metal-clad aluminum circuit board, features a lamination structure similar to other PCB types, comprising copper foil layers, solder mask, and silkscreen layers. However, unlike traditional FR4 or plastic substrates, Aluminum PCBs utilize a metal substrate. This substrate primarily Read more
What is In-Circuit Testing (ICT)? In-Circuit Testing (ICT) is a method used for testing electronic components and connections on a PCB to ensure their proper functionality. It is typically conducted early in the manufacturing process to detect and rectify any issues before defective products are delivered to customers. ICT involves Read more
Introduction In today’s landscape where electronic devices relentlessly pursue thinner profiles, higher integration, and greater reliability, traditional rigid printed circuit boards (PCBs) can no longer meet the demands of all applications. It is precisely this trend that has given rise to Flexible Printed Circuit Boards (Flex PCBs). With their unique ability Read more
Introduction Success in PCB board prototyping requires a meticulous approach to the entire product development cycle. This encompasses everything from initial schematic capture and component placement to advanced considerations of signal integrity (SI) and power distribution network (PDN) design during the PCB board prototyping phase, ultimately determining the prototype’s success. Phase 1: Pre-Design – Read more
Introduction This article focuses on comparing the two most prevalent solder compositions: 60/40 and 63/37 solder, often regarded as top choices for electronics soldering. These alloys are crucial for establishing reliable connections between different components. Let’s now delve into their key distinctions and advantages. 60/40 solder consists of 60% tin Read more
Introduction In the realm of printed circuit board (PCB) design and manufacturing, the transition from digital layout to physical board hinges on a critical element: the PCB Gerber file. This comprehensive guide delves into the intricacies of the Gerber format – the industry-standard data format that bridges the gap between Read more
What is a PCB Sensor? A PCB sensor is a critical component in electronic devices, enabling them to perceive, measure, and respond to changes in their environment, such as detecting temperature, pressure, motion, and humidity. These sensors are directly integrated onto the Printed Circuit Board (PCB), resulting in compact, efficient, Read more
