Single Sided Halogen Free FR4 PCB Printed Circuit Board Assembly
FASTPCBA FR4 PCB Manufacturer
FR4 pcb board is a very widely used printed circuit board. As you
know, it is cheaper than other laminated PCBs and is
fire-resistant. Therefore, these fiberglass epoxy laminated sheets
are in great demand in PCB assembly.
At FASTPCBA, we manufacture and deliver thousands of PCBs. We use
high-quality materials with optimum skilled manufacturing.
Therefore, we can make sure to present the best FR4 Printed Circuit
Boards for you.
Types of FR4 Materials and Parameters
Materials of FR4: In FR4 PCB fabrication, FR4 doesn’t use any
specific types of material. However, to determine the material of
manufacturing, the grade of material is more important than the
type of material.
Types of FR4 Printed Circuit Boards:
The types of FR4 boards depends on the method of classification.
According to the number of layers, they are divided into the
following types:
* Single-sided FR4 PCB
* Double-Sided PCB
* Multi-layer PCB
However, another classification of FR4 circuit boards is according
to the core material used in their fabrication. Usually, there are
two types of boards as per these criteria:
* Rigid FR4 boards
In the rigid FR4 printed circuit boards, the core material is FR4
only. Therefore, it is rigid for the whole board.
* Rigid-flex FR4 boards
These types of PCB boards have core materials that are rigid FR4
and flexible circuits.

FR4 PCB Uses and Applications
FR4 is much cheaper than the laminated boards. It is, therefore,
used in many complex devices. For instance:
* Relays of electric systems
* Electric switches
* Washers
* Standoffs
* Busbars
* Arc shields
* Screw terminal strips
* Transformers
