PCB uses the core component of electronic equipment, and basically all electronic products need to be used for PCB. There are many types of PCB, including single-layer, multi-layer, rigid, flexible, and so on. The more complex electronic products are, the more PCBs are required to cope. Now we focus on the relevant data of the 12-layer PCB.
PCB Layers Explained
The PCB layer refers to copper, and the first copper layer constitutes the original PCB layer. However, the PCB we see is not the whole copper skin, but the line. These lines are carved from the excess of the original layer of copper leather with chemical methods, leaving only the result of the line we want.
Then, use the insulated resin layer by layer, and the holes mentioned above are also made of resin, so that there are various layers of PCB.
How many layers does a PCB have?
Generally speaking, the number of layers does not have a certain standard, and it will be determined according to everyone’s needs for the PCB function. Let’s start with some conventional PCB board layers. Conventional PCB boards are divided into six layers, which are mechanical layers, forbidden wiring layers, welded layers, welded layers, wire printing layers, and pores.
If you are a PCB supplier, then you must know that PCB has multiple layers, such as 2 layers, 4th floor, 12 layers, and more than 20 and 30 layers. The higher the number of PCB layers, the higher the price, because the corresponding processing technical requirements are also higher. The number of PCB layers is determined according to the function of the product.
12 -layer PCB board
The 12-layer PCB board lays the foundation for modern automotive electronic circuits. They help fast track and reliable interconnection. They are used for many purposes, such as assembling electronic ignition systems, electronic helpers, gearbox control units, navigation systems and other vehicle components.
The 12-layer PCB is designed to withstand high temperature and pressure conditions. The main material used is polytide, which is an organic material that provides high heat resistance.
We use gold as a surface treatment material because it helps to withstand adverse
environmental use. In addition, we added a radiator to dissolve PCBs in high temperature applications. The 12 -layer PCB can withstand the thermal stress of 20 seconds in 288 ° C. The impedance capacity is controlled at about+/-10%. We offer custom PCB designs for different surface treatment preferences, such as lead-free HASL, carbon ink, tin and silver bars.

12 layer PCB stack and thickness
The 12-layer stack can meet the specific requirements of track height and material thickness when producing multi-layer printed circuit boards. There are two basic types of materials used in the 12th layer: prepreg and thickness. PRE-PREG is made of resin treated glass to fill the outer foil and the inner core gap of the outer layer other than the adhesive layer. In order to design the outer layer, a variety of copper foils of various weights (0.5 ounces or more) are used.
In most cases, the 12-layer PCB board is efficiently produced on a 1.6mm thick plate. More and more 14-16 layers are made of 1.6mm thick plates, while the number of 12-layer PCBs produced is limited to manufacturers that produce HDI boards. The number of HDI boards produced has increased.
Compared to other multi-layer circuit boards (such as 6-layer circuit boards, 8-layer circuit boards, and 10-layer circuit boards), the 12-layer PCB is cheap and more reasonable.
What is the standard size of the 12-layer PCB?
You can freely choose the 12-layer PCB layer that suits any type of application.
During the order, you must provide the manufacturer with the correct size of the 12-layer PCB layer.
If not, you may have to accept the standard size of the 12-layer PCB layer.
The following is the most common or standard 12-layer PC layer size.
The number of layers should be the standard 12 layer.
The thickness of the 12-layer PCB layer should be 1.8 mm
The welding layer should be green.
The main material of the substrate is FR-4, and the conductor material is copper material.
Surface treatment is Shen Jin surface treatment.
The figure is white.
12 layer PCB COST
One thing you must know is that the 12-layer PCB layer is very expensive, and you will have to spend money to buy them.
The manufacturing process is quite complex, and experienced manpower and special machines must be used in the manufacturing process.
In the long run, you ‘ll end up with a higher cost of high-quality 12-layer printed circuit boards.
If you use unswerving labor or manpower, low-quality machines and materials, you will spend less.
In the long run, this 12-layer PCB layer will reduce your cost, although they may not be reliable and durable.
In addition to quality and effect, you can also see the effect of quantity and size on the final cost of the PCB layer.
In this case, the more the 12-layer PCB layer, the higher the amount you pay.
In addition, the larger the size of the 12-layer PCB layer, the higher the amount you pay.
Application of 12-Layer PCB
The 12-layer PCB board lays the foundation for modern automotive electronic circuits. They help fast track and reliable interconnection. They are used for many purposes, such as the assembly of electronic ignition systems, electronic assistants, gearbox control units, navigation systems and other vehicle components, as well as USB wireless routers, Bluetooth USB hubs, Wi FI antennas and various Internetware, telephone systems, telephone systems, telephone systems, telephone systems, telephone systems, telephone systems , telephone systems, etc.
