FR4 Board Pcb FR4 Circuit Board 94v0 Double Sided FR4 Pcb



What is FR4?

FR4 PCB Board is the most common material grade that comprises fabricated circuit boards. ‘FR’ indicates the material is flame retardant and the ‘4’ indicates woven glass reinforced epoxy resin. Single or double-sided PCB structures consist of an FR4 core and top and bottom copper layers. Multilayer boards have additional prepreg layers between the center core and top and bottom copper layers. Now, the core consists of a substrate with copper covering, also referred to as a copper clad laminate. The core, laminate, and prepreg may all be FR4 with the copper sheets between the signal and ground layers.

The properties of FR4 may vary slightly depending on the manufacturer; however, it generally has favorable strength and water resistance attributes that support its widespread usage as an insulator for many electrical applications. It serves the same purpose in PCBs, namely to isolate adjacent copper planes and provide overall bending and flexural strength for the structure. FR4 is a good general purpose material for PCB fabrication; however, alternative materials are available.

Beneficial Properties of FR4 Circuit Board: 

The FR4 printed circuit boards have also gained popularity owing to the following reasons:

  •  FR4 is a low-cost material.
  •  It has a high dielectric strength which contributes to its electrical insulation properties.
  •  The material has a high strength-to-weight ratio and is lightweight.
  •  It is moisture resistant and has relative temperature resistance as well.
  •  The material has good electric loss properties.
  •  FR4 doesn’t absorb water, which makes it suited for various marine PCB applications, too.
  •  The material is yellow to light green in color, which perfectly goes with any application.

All these properties make it suitable in a variety of environments.
