What is FR-4?

FR4, also written as FR-4, is both a name and a standard rating. The name is applied to the fiberglass-reinforced epoxy-laminated sheets used in printed circuit board manufacturing. However, the name also functions as a grade used to rate epoxy laminate sheets. The designation essentially indicates the base quality of a laminate sheet, meaning a variety of sheet materials and designs fall under the FR4 rating. The “FR” in the name stands for flame retardant, while the 4 differentiates the material from others of the same class.

Properties of FR-4 Material

Flame Retardant
FR-4 is the most common printed circuit board material that uses Bromine, a halogen that has the properties to prevent or slow down the spread of fire.  It is also a standard material used for PCB by National Electrical Manufacturers Association (NEMA).
Excellent Electrical Properties
The FR-4 is used as the base material which makes its electrical properties important to be noticed.  As the electrical properties of a PCB material are crucial for signal integrity, impedance control, and the quality of insulation.

Electrical Properties Values by NextPCB
High Glass Transition Temperature 150Tg-170Tg
Decomposition Temperature >345 ℃
Low Co-efficient of Thermal Expansion 2.5%-3.8%
Dielectric Constant (@1 GHz) 4.25-4.55
Dissipation Factor (@1 GHz) 0.016
The raw material of FR-4 (Fiberglass and epoxy resin) makes it lightweight, cheap, and easily accessible.  Fiberglass provides good strength while epoxy resin holds the structure.  Together they provide an insulator with exceptional properties.
