What is Immersion Gold? Immersion gold, also known as electroless nickel immersion gold (ENIG), is a surface finishing process used in the production of printed circuit boards (PCBs). This process involves depositing a thin layer of gold over a nickel substrate through a chemical process, without the use of electrical […]

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.
