What is FR4?
FR4 is the name of a type of epoxy glazing material. fr stands for flame retardant. 4 refers to the factors that differentiate it from other materials. FR4 means two things.

The material.
As a construction material, it refers to epoxy laminates reinforced with glass fibers. Used to make FR4 printed circuit board.

Evaluation.
It is also a unit of evaluation. Epoxy laminates are classified. This classification shows the basic quality of the epoxy resin board.

This classification helps to determine the quality of different types of materials and designs of slabs.

What is FR4 PCB Assembly?
A circuit board with FR4 is called an FR4 PCB (fr4 printed circuit board). It is a type of printed circuit board that mainly uses FR4 boards. Originally, FR4 was used as an insulating layer for the PCB. Next FR4 manufacturer adds a layer of copper to both sides of the FR4 board. This makes it a CCL (copper clad laminate). Thanks to FR4, CCL acts as an insulating material. FR4 gives PCBs their strength. In addition, they perfectly absorb moisture and resist fire. This is why these boards are very popular in the market. There is a high demand for FR4 for PCB assembly. FR4 printed circuit boards are compact and easy to design. FR4 boards are popular because they are cheap and can be used in many electrical devices, GreensTone is an professional China fr4 pcb board manufacturer which you can trust.
