1. Understanding the Basics of LEDs 1.1 What are LEDs? LEDs are semiconductor devices that emit light when an electric current passes through them. They are made from materials such as gallium arsenide (GaAs) or gallium nitride (GaN), which determine the color of the light emitted. LEDs are known for […]

What are Surge Protector Circuits? Surge protector circuits are electronic components designed to absorb or divert excess electrical energy that may occur during a voltage surge. These surges can be caused by various factors, such as lightning strikes, power grid fluctuations, or the switching of large electrical loads. The primary […]

Understanding SMT Tombstoning SMT (Surface Mount Technology) tombstoning is a manufacturing defect that occurs during the Reflow Soldering process of surface-mounted components. It is characterized by one end of a component lifting off the PCB (Printed Circuit Board) pad, while the other end remains soldered, causing the component to stand […]
