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 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 […]

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 […]
