FR4 black epoxy board is made of fiberglass cloth impregnated with epoxy resin as adhesive, dried and hot-pressed into a board-shaped insulating material.
FR-4 is a flame-resistant material grade code, which means that the resin material must be able to self-extinguish after combustion, it is not a material name, but a material grade, so the FR-4 grade material used in general pcb boards has a very wide range of types, but most of them are based on the so-called four-function (Tera-Function). Epoxy resin plus filler (Filler) and glass fibers to make the composite material.FR4 laminated board, epoxy board, FR-4 light board, FR-4 glass fiber board, epoxy glass cloth board, epoxy glass cloth laminated board, circuit board drilling pad.
Main technical features and applications: stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for application in high-performance electronic insulation requirements of products, such as FPC reinforcement board, PCB drilling pads, fiberglass dielectrics, potentiometer carbon film printed fiberglass boards, precision vernier gears (wafer milling), precision test panels, electrical (electrical) equipment, insulating spacer, insulated pads, transformer insulation boards, motor insulation parts, grinding gears, electronic switch insulation boards and so on.
FR4 black material is widely used in the production of various circuit boards. Whether it is communication equipment, computers, consumer electronics or industrial control equipment and other fields, you can see the figure of FR4 black material. It serves as the substrate of the circuit board, carrying the connection and support of various electronic components, ensuring the stability and reliability of the circuit board. It also has good processing performance and can be cut, drilled, milled and other processing operations as needed, making it easy to produce circuit boards of various shapes and sizes. At the same time, it also has high strength and stiffness, and can withstand large mechanical and thermal stresses, ensuring the stable operation of the circuit board in a variety of complex environments.
With its excellent performance and wide range of applications, FR4 black material has become a robust cornerstone of the electronics industry. It carries the stable operation of circuit boards and provides a solid guarantee for the performance and reliability of electronic products.
