21 Οκτ 2024 · FR4 is a grade classification for a kind of material used in PCB manufacture that consists mostly of woven fiberglass. Some of the key properties of FR4 PCBs are signal integrity, dielectric strength, mechanical reliability, and resistance to harsh environment conditions.
23 Αυγ 2022 · The FR-4 is the most common dielectric material used in Printed Circuit Boards. This base material separates copper layers in the PCBs and provides mechanical support to the PCBs. It is a National Electrical Manufacturers Association (NEMA) standard for glass-reinforced epoxy laminate material.
This article delves into the core technical aspects of FR4 material in PCB design, focusing on its performance characteristics, limitations, and specific applications. At its core, FR4 is a composite material made from woven fiberglass cloth and epoxy resin, and it is flame retardant (hence the “FR” designation).
