12 Layer PCB: Its Circuit board, Fabrication, Stackup, and Application

Today, high-technology devices feature a high number of circuits having complex configurations. This is why accommodating these complex circuits could be difficult and impossible, if you don’t add layers to the stackup.

Furthermore, you will need to control the durability, thickness and the process involved in high-quality production. Taking a look at these basic needs and requirements for today’s electronic automotive devices, we have decided to cover this topic. If you wish to gain more knowledge about the 12 layer pcb, 12 layer circuit board, 12 layer pcb fabrication, and 12 layer pcb stackup, join us as we get started

What is 12 Layer PCB?

12 layer pcbs offer a foundation for the modern electronic circuits of automotives. They play a major role in fast tracking reliable interconnections. This PCB serves many purposes, including navigation systems, units for transmission control, assembling systems for electronic ignition, as well as other components of vehicles.

The 12 layer PCB design withstands stressful conditions and high temperatures. The major material used here is polyimide. This polyimide material is organic in nature, which offers great heat resistance.

When doing the surface finish for the 12 layer PCB, some top PCB manufacturers utilize Gold. This is because it plays a huge role in withstanding adverse environments. Furthermore, some add heat sinks to ensure that the PCB easily dissolves in applications working with high temperature.

Furthermore, at a temperature of 288 degrees centigrade and 20 seconds, 12 layer PCB attains thermal stresses, while its impedance control stands at about +/-10%. Compared to other multilayer boards like 8 layer and 10 layer, the cost for purchasing the 12 layer printed circuit board is affordable.

What is a 12 Layer PCB Stackup?

The 12 layer PCB stackup has to do with some requirements necessary for material thickness and tracking heights in the production of multilayer printed circuit board. 12 layer pcb stackup is necessary for arranging different layers of your printed circuit board to aid the designing of circuits on a single board.

Two major materials are necessary for the design of 12 layer PCB. These include the thickness and the prepreg. The prepreg involves resin-treated glass, which are useful in filling gaps in foils, as well as external layer cores apart from the bonding layers. In designing the outermost layer, use copper foils having different weights (at least 0.5 ounces).

In most cases, the 12 layer PCB is efficiently produced on boards with 1.6mm thickness. Furthermore, the fabrication of additional 14 to 16 layer boards occur into these thick boards. Furthermore, the number of boards you are producing depends on the manufacturers producing HDI boards.

What is 12 Layer PCB Fabrication?

There are different processes involved in 12 layer pcb fabrication. These processes have to do with the assembling, as well as the stacking of 12 layers together by distributing the insulating material between the copper layers. These are the processes involved in 12 layer pcb fabrication.

The first step is the imaging. Here, you actualize the digital design on the board. You then transfer it to the circuit board, from the software.

The next step is to remove extra metal from the printed circuit board making use of an industrial solvent. This process is etching. The next stage here is laminating the 12 layers. Here, you will combine the 12 layers of the PCB making use of a pressing machine. This helps you to generate a single board.

Next is machining the 12 layer. This step, the drilling of the via and through hole takes place. With this drilling, you facilitate the connections found between this PCB’s 12 layers. The last step for the 12 layer PCB fabrication is plating. Here, you simply apply metal finish to the via and through-hole.

What is a 12 Layer PCB Circuit Board?

The 12 layer PCB circuit board is smaller in contrast to the double or single-layer type. This small size is possible because these 12 layers are stacked upon each other and they are also connected through vias.

What results is a dense, compact, small printed circuit board, which is useful in producing laptops, mobile phones, and more. Furthermore, the design produces lighter printed circuit boards as a result of its small size. Due to this reason, you can easily handle and carry them around.

In addition, you can design 12 layer pcbs in a way that shows high-quality. Fabricating the 12 layer pcb circuit board takes a long time in contrast to the double and single layer type. It is strong and durable because this PCB has 12 layers and all these layers are stacked up.

Asides from this, during processing, they undergo high temperatures. Furthermore, the laminates for the binding of these layers play a huge role in its durability.

12 layer PCB circuit boards possess more density in contrast to the double or single layer type. This allows the soldering of more components on a very small surface, as a result, there is an improvement in the efficiency of the PCB.

Asides from this, 12 layer PCB circuit boards function efficiently due to the fact that with its small space, it has more circuitry. This is why devices using this type of board are usually very powerful and work at high speed. This is why they are useful in supercomputers, graphic cards, equipment for crypto mining, quantum computing, and artificial intelligence.

Applications of 12 Layer PCB

12 layer printed circuit boards are useful in the following areas:

  • Consumer electronics
  • Computer electronics
  • Telecommunication
  • Medical devices
  • Aerospace and military


By now, you should have a clear understanding of what 12 layer pcb, 12 layer circuit board, 12 layer pcb fabrication, and 12 layer pcb stackup is. 12 layer pcb has a lot to offer due to its small size. It is very useful in different applications. As usual, make sure you work with the best manufacturers for your 12 layer PCB. By this, you can be sure that the right processing methods will be useful and the design will come out according to your requirements.
