In our increasingly digital world, printed circuit boards (PCBs) are the silent workhorses powering virtually every electronic device we encounter, from the smartphone in your pocket to the complex systems guiding satellites. FR-4 PCB material forms the core of most printed circuit boards. Often going unnoticed, FR-4 is the fundamental substrate that provides the strength, […]
In this article, you will learn how to design a 12V 5A SMPS circuit that converts 230VAC to regulated 12V DC using the TOP227YN in a flyback configuration. Switched Mode Power Supplies (SMPS) are widely used for high-efficiency AC-to-DC conversion. The flyback topology is especially suitable for low- to medium-power isolated supplies. The TOP227YN is […]
Artificial Intelligence in Electronics improves quality, inspection, and yield as components shrink and manufacturing complexity increases. Electrical components are becoming smaller and denser, making them harder to manufacture consistently. Fine-pitch BGAs, advanced packaging, high-speed connectors, miniaturized sensors and power electronics all push tolerances to their limits, while OEMs still expect faster ramp-ups, tighter reliability targets […]
Printed Circuit Board (PCB) assembly is the heart of modern electronic product manufacturing. Two primary methodologies dominate PCB assembly: Surface Mount Technology (SMT) and Through-Hole Technology (THT). Each technology has unique characteristics, advantages, limitations, and ideal use cases. This article presents a detailed, side-by-side examination of SMT and THT, covering fundamentals, process steps, component types, […]
When you pause to consider why your smartphone starts behaving erratically after exposure to bathroom steam, or why an inexpensive kitchen timer fails after spending months near a hot stove, you are touching on one of the most demanding disciplines in electronics engineering: designing systems that can survive in harsh environments. Few environments are as […]
This article explores various types of PCB materials, their composition, electrical and mechanical properties, advantages, disadvantages, and applications in different industries. Printed Circuit Boards (PCBs) form the backbone of almost every modern electronic device — from small gadgets to industrial machines and communication systems. The performance, durability, and reliability of a PCB depend largely on […]
