Understanding the Basics of Automatic Voltage Regulators Before diving into the construction process, it is crucial to understand the fundamental concepts behind AVRs. In this section, we will discuss the purpose of an AVR, its basic components, and how it maintains a stable output voltage. What is an Automatic Voltage […]

What is Immersion Silver PCB Finish? Immersion silver (IAg) is a popular surface finish for printed circuit boards (PCBs) that provides excellent solderability, conductivity, and shelf life. It is a lead-free, RoHS-compliant finish that deposits a thin layer of pure silver onto the copper pads and through-holes of a PCB. […]

What is FR4-TG? FR4-TG is a high-performance variant of the standard FR-4 (Flame Retardant 4) printed circuit board (PCB) material. It is a glass-reinforced epoxy laminate that offers enhanced thermal stability and improved mechanical properties compared to conventional FR-4. The “TG” in FR4-TG stands for “Tg,” which refers to the […]

What is PCB Prepreg? PCB prepreg is a composite material that is used as an insulating layer between the conductive copper layers in a Multilayer PCB. The prepreg material is made by impregnating a reinforcement fabric, usually fiberglass, with a thermoset resin, such as epoxy or polyimide. The resin is […]

Introduction to Wire Bonding Wire bonding is a widely used interconnection technology in the semiconductor packaging industry. It is a process that involves connecting the chip’s bond pads to the package leadframe or substrate using thin metal wires, typically made of gold, aluminum, or copper. Wire bonding has been a […]

What is Multilayer PCB Pressing? Multilayer PCB pressing is a crucial step in the manufacturing process of printed circuit boards (PCBs) that have more than two layers. It involves stacking and bonding multiple layers of PCB material together under high pressure and temperature to create a single, unified board. This […]

Introduction to Light Sensor Circuit A light sensor switch circuit is an electronic device that detects the presence or absence of light and triggers a corresponding action, such as turning a device on or off. These circuits are widely used in various applications, including automatic lighting systems, security systems, and […]

Introduction to Clap Switch A clap switch is an electronic device that can be used to turn electrical appliances on or off by simply clapping your hands. It is a fun and easy project for beginners who are interested in learning about electronics and circuit design. In this article, we […]
