FR4 Material Multilayer Pcb

Product Detail

FR4 material multilayer pcb came into being for the ever-changing changes in the electronics industry. Over time, the functions of electronic devices have gradually become more and more complex, requiring more complex PCBs.

The structure of FR4 material multilayer pcb is as follows:

1. Signal layer

AlTium Designer provides up to 32 signal layers, including top, bottom, and middle layers. The layers can be connected to each other through vias, blind vias and buried vias.

(1) Top signal layer

Also known as the component layer, it is mainly used to place components. For double-layer boards and multi-layer boards, it can be used to arrange wires or copper cladding.

(2) Bottom signal layer

Also known as the solder layer, it is mainly used for wiring and soldering, and can be used to place components for double-layer boards and multi-layer boards.

(3) Intermediate signal layer

There can be up to 30 layers, which are used to arrange signal lines in multi-layer boards, excluding power lines and ground lines.

2. Internal power layer

Usually referred to as the inner electrical layer, it only appears in multi-layer boards. The number of PCB board layers generally refers to the sum of the signal layer and the inner electrical layer. Similar to the signal layer, the interconnection between the inner electric layer and the inner electric layer and between the inner electric layer and the signal layer can be realized by through holes, blind holes and buried holes.

Advantages of FR4 material multilayer pcb

From a technical point of view, multilayer PCBs offer several advantages in terms of design. These advantages of multilayer printed circuit boards include:

1. Small size: One of the most prominent and praised benefits of using multilayer printed circuit boards is their size. Due to its layered design, the multilayer PCB itself is smaller than other PCBs with similar functions. This brings huge benefits to modern electronics as the current trend is towards smaller, more compact yet more powerful gadgets such as smartphones, laptops, tablets and wearables.

2. Lightweight structure: With a smaller PCB, the weight is lighter, especially because the multiple connectors required for the interconnection of single-layer and double-layer PCBs are eliminated, which is beneficial to the multi-layer design. This again is good for modern electronics, which are more inclined towards mobility.

3. High quality: Due to the amount of work and planning that has to be done when manufacturing a multilayer PCB, these types of PCBs tend to be better than single and double layer PCBs. Therefore, they are also more reliable.

4. Improve durability: Multilayer PCBs tend to be durable by their nature. Not only must these multilayer PCBs hold their own weight, but they must also be able to handle the heat and pressure used to bond them together. In addition to these factors, multilayer PCBs use multiple layers of insulation between circuit layers, binding them together with prepreg adhesives and protective materials.

5. Increased flexibility: While this does not apply to all multilayer PCB assemblies, some do employ flexible construction techniques, resulting in flexible multilayer PCBs. This can be a very desirable characteristic for applications where slight bends and bends may occur on a semi-regular basis. Again, this does not apply to all multilayer PCBs, and the more layers you add to a flex PCB, the less flexible the PCB will be.

6. More powerful: Multilayer PCBs are extremely high-density components that combine multiple layers into a single PCB. These close proximity make circuit boards more connected, and their inherent electrical properties allow them to achieve greater capacity and speed, albeit in a smaller size.
