When you are designing or assembling a PCB, the more layers you add, the higher your cost will be. However, the PCB design is much more complicated than that as it involves many other factors. Therefore, considering these factors will help you understand the cost per layer much better.
So, here is a complete guide that will help you understand the 6-layer vs 8-layer assembly cost in detail.
Factors Affecting The PCB Assembly Cost
It is crucial to note that different factors will affect the PCB assembly cost no matter how many layers you add. These include:
1. The Material Choice
Of course, the material will affect the PCB assembly cost in the most significant manner. For example, a standard PCB is usually laminated with a flame retardant 4 (FR4). However, it is not the ideal material choice for PCBs with high-intensity use, such as those in aerospace or fuel industries.
The material choice will affect not only the cost but also the durability and sustainability of your PCB. That is why it is crucial to choose the right material that will offer you a cost-effective solution.
2. Size
Size is another factor that will affect the cost of your 6-layer or 8-layer PCB. You must also remember that the number of circuits you need for the design will also determine the board size you select. So, be sure to opt for the right size that can hold the layers and the number of circuits you need.
3. 6-Layer Vs. 8-Layer Cost
Now, to answer your question, the 6-layer and 8-layer costs will also be different. Of course, the more layers you have, the higher your cost will be when designing the PCB. That is because you will also need more materials, and the size of the PCB will also increase.
Keep in mind that your cost will increase 30% from the standard price when you add six layers. On the other hand, your cost will increase 35% from the standard price when you add eight layers to your PCB. PCB assembly manufacturer will give you a better quote estimate according to your PCB needs.
4. PCB Finishing
Even the PCB finishing will affect the assembly cost no matter how many layers you have. Some finishes have a longer shelf life and are a higher grade. You can choose any finish you like depending on the unique features.
Some of the most common finishes include HASL, OSP, LFHASL, IMM Sn, IMM Ag, ENEPIG, ENIG, Elec Au, and many others. Each finish will offer you something different. That is why you must select what you prefer and what will be the most advantageous for you.
5. Custom Specifications
Finally, if you have any other specifications for your PCB apart from the six or eight layers, then that will also affect the cost of your PCB assembly. Your unique specifications will add to the cost because they require more materials and resources in the manufacturing process. That is why it is best to talk to your PCB manufacturer.
Once you set out your layers, specifications, size, and other factors, they will give you a much better idea of the assembly cost. It will help you understand whether the PCBs are in your budget or not.
Final Words
That is everything you need to know about the six-layer and eight-layer assembly costs of the PCB. As you add more layers and other specifications, the cost will increase significantly.
