Come and learn about fr-4 epoxy glass cloth laminate

Let everyone know about fr-4 epoxy glass cloth laminate! Everyone should be familiar with this! FR-4 is the code name of a flame-resistant material grade. It represents a material specification that the resin material must be able to extinguish by itself after burning. It is not a material name, but a material grade. Therefore, the current general circuit There are many types of FR-4 grade materials used in the board, but most of them are composite materials made of so-called four-function epoxy resin, filler and glass fiber.

FR-4 epoxy glass cloth laminate, according to different uses, the industry is generally called: insulating board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4, fiberglass board, fiberglass board , Flame-retardant insulation board, FR-4 laminated board, epoxy board, FR-4 light board, FR-4 fiberglass board, epoxy glass cloth board, epoxy glass cloth laminate, circuit board drilling pad. Main technical features and applications: stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for high-performance electronic insulation products.

Let me talk about its characteristics first: FR-4 epoxy glass fiber cloth substrate is a kind of substrate that uses epoxy resin as adhesive and electronic grade glass fiber cloth as reinforcing material. Its bonding sheet and inner core thin copper clad laminate are important substrates for making multilayer printed circuit boards.

Let’s talk about its performance: The mechanical properties, dimensional stability, impact resistance, and moisture resistance of the epoxy glass fiber cloth substrate are higher than that of the paper substrate. Its electrical performance is excellent, the working temperature is relatively high, and its performance is less affected by the environment. In terms of processing technology, it has great advantages over other resin glass fiber cloth substrates. This type of product is mainly used for double-sided PCB, and the amount is large.

Finally, talk about its application: epoxy glass fiber cloth substrate, the most widely used product model is FR-4. In recent years, due to the development of electronic product mounting technology and PCB technology, FR-4 products with high Tg have appeared.
