As a manufacturing material, it means fiberglass-reinforced epoxy-laminated sheets. it is used in FR4 PCB manufacturing.An FR4 PCB is a printed circuit board made with FR4. FR4 is the most important material in the PCB assembly. Electric engineers and technicians popularly use PCB boards with the FR4 material. We are FR4 Manufacturer in China.

What is FR4 material? FR4 Material, and Grading: As a manufacturing material, it means fiberglass-reinforced epoxy-laminated sheets. it is used in FR4 PCB manufacturing. It is also a rating unit. The epoxy laminate was graded. This grading indicates the base quality of an epoxy sheet.This rating helps in determining the quality of various types of sheet materials and designs.

A print circuit board with FR4 is called the FR4 PCB board. It is a printed circuit board that essentially uses the FR4 sheets. At first, the FR4 is used in the insulating layer of the circuit board. Then, we add a copper layer on either side of the FR4 sheet. As a result of this, it becomes CCL (Copper Clad Laminate). Due to FR4, CCL acts as an insulating material. It is then used in manufacturing FDR PCB boards.The FR4 gives PCB boards a strength. Moreover, they are great at absorbing moisture and resisting fire. Therefore, these boards are very popular in the market.

Features of FR4 to Consider When Choosing FR4 PCB:When choosing or ordering FR4 printed circuit board, an electrical engineer or technician must look at the following features:Thickness:The thickness of an FR4 sheet varies depending on your project. Ideally, you will require an FR4 with a thickness of 1.3 thou to 3 inches. Impedance Matching:The impedance matching is very important in high-frequency PCBs. It helps to maintain the function of the board of directors. It also determines the capacitance of the layers in multi-layered boards.

Space & Flexibility: Depending on your project, you can choose an FR4 material for your PCB boards. Mostly, people prefer thinner sheets as they take less space and are more flexible. Weight of the FR4:Since, the thickness of the board determines its weight. For lighter products, choose FR4 boards with lighter weight. Thermal Conductivity:To determine the temperature management of the FR4, look at the value of the thermal coefficient of dielectric constant. However, FR4 is heat resistant and it is one of the main reasons for its popular use.
