What’s FR4 PCB Board?
A print circuit board with FR4 is named the FR4 pcb. This is a printed circuit board that essentially uses the FR4 sheets.
To start with, the FR4 is used in the insulating layer of the circuit board. Then, we put in a copper layer on either side in the FR4 sheet.
Because of this, it will become CCL (Copper Clad Laminate). On account of FR4, CCL works as an heat retaining material.
It is then used in manufacturing FDR PCB boards
The FR4 gives PCB boards a strength. Moreover, they’re great at absorbing moisture and resisting fire.
Therefore, these boards are incredibly popular in the market.
Popular features of FR4 to Consider When Choosing FR4 PCB
When selecting or ordering FR4 pcb, a power engineer or technician must go through the following features:
Thickness:
The thickness of an FR4 sheet varies according to assembling your project. Ideally, you’ll need an FR4 which has a thickness of a single.3 thou to 3 inches.
Impedance Matching:
The impedance matching is vital in high-frequency PCBs. It will help to maintain the function from the board of directors. Additionally, it determines the capacitance with the layers in multi-layered boards.
Space & Flexibility:
According to any project, you can pick an FR4 material to your PCB boards. Mostly, people prefer thinner sheets while they take less space and therefore are more flexible.
Weight of the FR4:
Since, the thickness from the board determines how light it is. For lighter products, choose FR4 boards with lighter in weight.
Thermal Conductivity:
To discover the temperature control over the FR4, look at the value of the thermal coefficient in the dielectric constant. However, FR4 is heat resistant and it’s also one of the many factors behind its popular use.
