Description:

Fr-4, also known as FR-4 or FR4, represents a flame retardant, and four represent a class of materials used. Fr-4 is both a name and a rating. It is used as a name when manufacturing PCB and fiberglass reinforced epoxy laminates. As a rating, Fr-4 is used for the classification of epoxy laminates as an indicator of its quality.

If you work with FR4 2 Layer PCB For Power Bank often, you are probably familiar with Fr-4 materials. It is a popular PCB base material because it is the main component used to make rigid boards.

The Fr-4 material is a structure mainly composed of glass fibers woven into a thin sheet of cloth. Glass fiber makes Fr-4 a solid foundation for the manufacture of rigid boards. It is enclosed in refractory epoxy and is a source of rigidity.

Features:

One of the other reasons why Fr-4 is popular is due to the low cost and versatility of its materials. The FR-4 board has a large dielectric strength as an electrical insulator. In addition, they are lightweight, water and heat resistant, and in short, it is a material suitable for various environmental conditions.
