8 Layer PCB
8 layer PCB has 8 layers circuit boards. They are fixed tightly together with reliable, common relations between each of the layers. It has more compound arrangement and its stack-up gives sufficient routing space for a lot of power islands. 8 layers printed circuit board is installed usually into compact devices with strict necessities of spacing, devices like Digital cameras, cell phones, passive switch boxes, Radios, etc. In a typical 8 Layer PCB stack-up design, we have the single layer PCB, the double layer PCB, and the multilayer PCB, which is a PCB with three or more conductive layers.
When making a PCB design, we use a single or two-layer PCB. A two-layer PCB is adequate to handle the requirement of the job. Therefore, in order to reduce the risk of avoidable problems, it is best to keep the PCB design direct. We must preserve the design of the circuit board directly, but under some conditions, a multi-layer circuit board design is required. Having an 8 Layer PCB board is not common, but it is practiced frequently in some applications.
An 8 Layer PCB board can be used to add two additional routing layers or to improve the ECM performance by using an additional two or more planes. We can see an example of each case. Most of them are used to increase EMC performance as an alternative of adding extra layers for routing. Therefore, in order for the 8 layers to work well and have good EMC characteristics, each layer of signals should follow a balanced structure, such as a power plane or ground plate.In addition, attention should be paid to the space between the layers, especially the tracking space between the signal layer and the ground plane.
A vital aspect in determining where and how to use the PCB is its thickness. A customer or designer has to provide information about where and how it is used. This allows you to determine the exact thickness appropriate for your application and area of use. The thickness of a standard PCB also depends on the layer of the foil.
Finally, for an 8-ply board, the standard PCB thickness is 0.062, 0.093, and 0.125 inches. You can also make a choice between different layers of copper foil based on the requirement for your board. You can also make use of a dielectric structure or a controlled stack.
- Do not cut the base layer
- Do not leave anything unattached
- Always deliver a common ground point
- Accurately design your ground before routing
- Know where your currents are going
- Always plan for dynamic variance between grounds
- Mind your mixed-signal floor arrangement
8 layer Printed circuit board is usually used in compact devices that need a limited arrangement. And as a result of its complexity and high cost, your 8 layers PCB should be produced by a skilled and professional PCB manufacturer.
