Understanding FR4 Rigid Circuits: FR4 Rigid Circuits FR4 Rigid Circuits 1. Characteristics: FR4 Rigid Circuits Material Composition: FR4 is a type of flame-retardant laminate made from woven fiberglass cloth impregnated with epoxy resin. This composite material offers excellent mechanical strength, dimensional stability, and electrical insulation properties. Layer Structure: FR4 rigid circuits typically consist of multiple layers of copper traces sandwiched between layers of FR4 laminate. These layers are bonded together under high pressure and temperature to form a rigid, durable substrate. 2.
