What’s FR4 PCB Board?
A print circuit board with FR4 is called the FR4 printed circuit board. This is a printed circuit board that essentially uses the FR4 sheets.
At first, the FR4 is utilized from the insulating layer in the circuit board. Then, we give a copper layer on either sides from the FR4 sheet.
As a result of this, it will become CCL (Copper Clad Laminate). Because of FR4, CCL acts as an insulating material.
Then it is found in manufacturing FDR PCB boards
The FR4 gives PCB boards a strength. Moreover, they are effective in absorbing moisture and resisting fire.
Therefore, these boards are very popular in the market.

Features of FR4 to think about In choosing FR4 PCB
When selecting or ordering FR4 pcb, a engineer or technician must consider the following features:

Thickness:
The thickness of your FR4 sheet varies according to any project. Ideally, you will need an FR4 which has a thickness of 1.3 thou to 3 inches.

Impedance Matching:
The impedance matching is very important in high-frequency PCBs. It can help to keep the function in the board of directors. What’s more, it determines the capacitance in the layers in multi-layered boards.

Space & Flexibility:
Based on any project, you can select an FR4 material on your PCB boards. Mostly, people prefer thinner sheets because they take less space and are more flexible.

Weight with the FR4:
Since, the thickness from the board determines the weight. For lighter products, choose FR4 boards with lighter weight.

Thermal Conductivity:
To discover the temperature treating the FR4, glance at the worth of the thermal coefficient in the dielectric constant. However, FR4 is heat resistant and it is one of the many reasons behind its popular use.
