FAQs about 10 Layer PCB
1. What is 10-layer PCB?
A 10-layer PCB is a printed circuit board with ten layers. You use this multilayer PCB when you need six routing layers. Further, applications that require proper electromagnetic conductivity also need 10-layer PCBs.
In this 10-layer PCB, all the layers are tightly bound to establish a strong relationship between each layer. These PCBs deliver good performance as there is a strong connection between the return plane and the signal layer.
2. What is a 10-layer PCB stack up?
The 10-layer Printed Circuit Board has six signal layers and four plane layers. You can create a stack board with good electromagnetic conduction with six layers and four planes.
The sample arrangement of the 10-layer PCB board is as follows:
3. What are the materials in 10-layer PCB?
A 10-layer printed circuit board comprises several layers. However, you need to fabricate and laminate the layers to form a 10-layer stack. Different layers use different materials. If you start with the bottom, here are the main types of materials that you use in PCB fabrication.
Firstly, the substrate layer has glass epoxy materials which are Fr4 materials. The epoxy has fire resistance and flame retardant properties, and these materials have high tensile strength and thus provide a good foundation for a 10-layer PCB.
Fr4 materials are expensive, but you can also choose epoxies and phenolics as cheaper options. However, such cheap materials lose lamination very soon. Additionally, these cheap materials also release a foul smell during soldering.
Copper materials are laminated on the substrate layer using heat and adhesives. The copper layer is thinner than other materials and provides connectivity to the circuit.
The silkscreen layer is the topmost layer of the 10-layer PCB and it acts as a reference indicator to place different components on the PCB. PCB manufacturers use permanent non-conductive epoxy ink to print graphics and text on the PCB. Usually, the color is white, but other colors are also available now.
Solder mask materials
Solder mask materials help solder the exposed metals to protect them and reduce the chances of short circuits.
4. What are the applications of 10-layer PCB?
10-layer PCBs have multiple benefits, and thus you can use them in a wide range of applications. Some of the industries where you can use these 10-layer PCB stack-ups are:
- Consumer electronics
- Medical equipment
- Military and defense
- Computer electronics
- Industrial processing
- Aerospace and aviation
5. What is the dimension of a standard 10-layer PCB?
The PCB industry has different types of 10-layer PCBs. The difference occurs due to the differences in dimensions of the board. You will find different styles and varieties in 10-layer PCBs due to differences in dimensions. Opt for the standard sizes to get the perfect 10-layer PCB for your applications.
Here are the standard dimensions of a 10-layer PCB.
PCB thickness: In a standard 10layer PCB, the PCB can have a thickness of 1.3mm, 1.6mm. 2.0mm, 2.4mm, and 3.0mm. Your application requirements decide which thickness will be suitable for your application.
Copper thickness: Another critical dimension of a 10-layer PCB is the thickness of copper. The copper thickness refers to the weight of the copper used in the PCB board. Typically, the thickness of a copper-clad laminate is 0.5Oz per sq. ft or 1oz per sq. ft. The difference in the copper thickness brings the difference in the DC resistance. If the copper layer is thicker, the DC resistance of traces and planes is smaller. As a result, there is a few mV of the voltage drop between the load component and power output.
6. What are the disadvantages of 10-layer PCB?
The 10-layer PCB is very advantageous for you in different applications, the designing process of 10 layers takes a lot of time and money. Some disadvantages outweigh its advantages and thus make it unsuitable for various applications.
Complex manufacturing process: In a 10-layer PCB, stacking the layers, placing its components, and coupling the different layers is difficult. The whole manufacturing process is very complex and leads to many problems while designing. Complexities increase if you are producing the board physically, and even a tiny flaw in the manufacturing process can lead to an invalid PCB.
Need technical designers: As we said, 10-layer PCBs need a lot of complex design; you might need expert technicians and designers for their creation. The designers must have prior experience in 10-layer PCB manufacturing, and there is a scarcity of such experienced designers and technical experts, which further adds to the cost of PCB manufacturing.
Production time: As the production processes are complex, every step needs a lot of time to complete. Sometimes an error occurs, and it becomes difficult to mend these errors on time. As a result, the production time increases. This increased time, in turn, leads to a longer time gap between order placed and order delivered.
Limited availability: Due to the complex design process, the machines used to manufacture 10-layer PCBs are limited. Not all PCB manufacturers have these machines or can afford them. So, if you want 10-layer PCBs, it is better to discuss them regarding the availability of machines and their capability in multilayer PCB manufacturing.
Higher costs: All the above factors like limited and costly machines, complex design, and higher production time lead to higher manufacturing costs of a 10-layer PCB. Further, errors lead to many reworks, adding extra labor and scrap costs.
7. What is the storage condition of the 10-layer PCB?
After manufacturing, storing the 10-layer PCBs in appropriate conditions is essential to avoid electrostatic discharge. Additionally, it is also necessary to protect it from moisture.
PCB Manufacturers store these PCBs in moisture barrier bags which are vacuum sealed. Desiccant bags and cards are used in the storage to indicate the humidity level in the storage. You need to store the PCBs in a dry package and in dry conditions away from moisture.
8. How do you select the EMC of a 10-layer PCB?
EMC stands for electromagnetic conductance. To determine the right electromagnetic conductance for 10-layer PCB, you need to maintain several aspects.
Some of the factors that you should consider are:
- Look for the number of layers in PCB, which is 10 in this case
- Determine the type of layers, such as plane layers, ground layers, or signal layers
- Order or arrangements of different layers on the printed circuit board
- Spacing between each layer
- Deciding signal layer pairs for orthogonal routing of various signals
- Assigning different signals to the routing layers
9. What is the cost of a 10-layer PCB?
There is no fixed price for a 10-layer PCB. 10-layer PCBs are of different types, and different types differ in their costs. Further, the cost also differs from manufacturer to manufacturer. Several factors bring the difference in the price of PCB, such as:
- Choice of materials
- Size of PCB
- Type of finish in PCB
- Size of the holes in the board
- Minimum trace width and spacing
- PCB thickness and aspect ratio
- Addition of any customized specifications
