8 Layer PCB

8 Layer PCB - Stackup & Cost & Prototype manufacture

What is 8 layer PCB?

The 8 layer PCB is a circuit board with 8 layers that are stacked firmly together with predefined and dependable mutual connections between the layers. Structure of eight layer PCB is more complicated. Nowadays, PCBs frequently have 8 to 12 layers or more, and electronics engineers know that designing for so many layers requires a well-configured layer stack.

8-layer printed circuit boards are usually installed in compact equipment with strict spacing requirements, such as notebook computer motherboard, communication backplane, wearable watches, etc. Because of its complexity and high manufacturing costs, your 8-layer PCB manufacturing should be made by reliable and experienced manufacturers. Jinghongyi PCB has been specially targeting high-end PCB manufacturing and assembly services for 8 years, providing high-quality products and services for various customers. Our advanced production line and fast response team will keep you comfortable and reassured, without any trouble, you can rest assured to place the order with us.

Typical 8-layer PCB stack up methods and guidelines

Standard stackup of 8 layer PCB looks as follows

1. Signal1
2. Ground
3. Signal2
4. Power
5. Ground
6. Signal3
7. Power
8. Signal4

Eight-layer PCB can be used to add two additional layers, or two planes can be added to improve EMC performance. Most eight-layer circuit boards are superimposed to improve EMC performance, rather than adding additional wiring layers. Compared with 6-layer circuit boards, the cost increase percentage of 8-layer PCB is less than that of 4-layer PCB to 6-layer PCB. Therefore, in order to improve EMC performance, the cost increase is reasonable. Therefore, most 8-layer boards consist of four wiring layers and four planes.

8 Layer PCB Stack up

8 Layer PCB stackup

In short, 8 layer PCB are usually used to improve the EMC performance of circuit boards, rather than increasing the number of layers.

No matter how you decide on the stack layer, it is not recommended to use an 8-layer PCB board with six wiring layers. If you need six routing layers, you should use a 10 Layer PCB board. Therefore, the 8-layer board can be regarded as the six-layer board with the best EMC performance.

Basic Layer of Eight-Layer Circuit Board with Excellent EMC Performance

All signal layers are adjacent to the plane, and all layers are tightly coupled. High-speed signals are buried between planes, so planes provide shielding to reduce the transmission of these signals. In addition, the circuit board uses multiple grounding layers to reduce the grounding impedance.

Other forms of 8-layer PCB stackup

A typical 8 Layer PCB Stackup

0.062[8 layer PCB stackup

0.093[ 8-Layer PCB Stackup

Let's conclude that using more than eight layers of PCB has almost no EMC advantage. Usually only 8 layers are used when additional layers are needed for signal tracking routing. If six layers of wiring are needed, 10 layer PCB should be used.

So far, we have also clarified the cost and price differences between 6-layer PCB, 8-layer PCB and 10-layer PCB.
