What’s FR4 PCB Board?
A print circuit board with FR4 is named the FR4 pcb. It is just a printed circuit board that essentially uses the FR4 sheets.
At first, the FR4 can be used from the insulating layer of the circuit board. Then, we add a copper layer on each side with the FR4 sheet.
As a result of this, it becomes CCL (Copper Clad Laminate). Because of FR4, CCL works as an heat retaining material.
Then it is used in manufacturing FDR PCB boards
The FR4 gives PCB boards a strength. Moreover, they’re effective in absorbing moisture and resisting fire.
Therefore, these boards have become popular out there.
Features of FR4 to Consider In choosing FR4 PCB
In choosing or ordering FR4 printed circuit board, an electrical engineer or technician must consider the following features:
Thickness:
The thickness of your FR4 sheet varies according to your project. Ideally, you’ll need an FR4 which has a thickness of a single.3 thou to three inches.
Impedance Matching:
The impedance matching is vital in high-frequency PCBs. It can help to keep up the function from the board of directors. In addition, it determines the capacitance from the layers in multi-layered boards.
Space & Flexibility:
Depending on your project, you can select an FR4 material for your PCB boards. Mostly, people prefer thinner sheets while they take less space and therefore are more flexible.
Weight with the FR4:
Since, the thickness from the board determines its weight. For lighter products, choose FR4 boards with less heavy.
Thermal Conductivity:
To look for the temperature control over the FR4, glance at the valuation on the thermal coefficient in the dielectric constant. However, FR4 is heat resistant in fact it is one of the many factors behind its popular use.
