PCBTok’s Blind Vias PCB can Help your Business
PCBTok has a wide range of blind via PCBs for your business. Blind via PCB is an important part of the PCB manufacturing process. It allows you to connect two different layers of your circuit board without having to drill a hole in the board or use a through-hole component. Blind vias have many applications in various industries, and they are also used in many different types of electronic devices, such as computers, cell phones, and automotive systems.
In order to create a blind via in your circuit board, you will need to use a special tool called a laser drill machine. This machine uses high-powered laser beams to burn through the copper layers of your board so that metal can be placed between them for conductivity purposes.

- Low cost: You can get started with one of our blind vias PCBs for less than $100! Compare this to other products on the market today—we guarantee that ours will save you a lot of money!
Blind Vias PCB Fabrication
With years of experience in designing and manufacturing PCBs, we have accumulated abundant technical resources and professional talents to provide customers with quality products and excellent service.
Besides, we have set up an efficient production line with advanced equipment, such as automatic laser machine, CNC drilling machine, automatic laminating machine, automatic drilling machine and automatic soldering machine, etc.
We are committed to providing you with quality tested buried vias PCBs at an affordable price. Our entire team is dedicated to providing you with the best customer service possible so you can be confident in your purchase.
Blind vias are not just holes that are drilled in the circuit board, but they are holes that are drilled in the circuit board and filled with solder. This process can be used to connect two layers of the circuit board together at an angle.
The solder is melted and allowed to cool, creating a solid connection between the layers. This type of connection is more secure than soldering directly onto the copper traces.
It also allows for a more flexible design because you can use larger hole sizes than would otherwise be possible with ordinary through-hole components. This can improve the reliability of electronic devices and reduce costs on maintenance and repair.

Blind Vias PCB: The Ultimate FAQ Guide
First, you may be curious about how blind vias work. The concept is similar to that of a standard PCB. Blind vias are board holes formed by drilling through the central core layer and the surface layer. These layers are then stacked using prepreg material. Blind vias have many applications. This guide will explain the basic principles of blind vias and how they work.
While blind vias are used to connect PCB layers, buried vias are more common. They provide improved power transfer and layer density but have a negative impact on signal quality. Because buried holes are less visible, designers can make boards smaller and lighter. Medical devices, tablets, and cell phones are examples of products that use buried holes. The Ultimate FAQ Manual
The size of any through-hole must be carefully considered. A 10 mil finished hole is considered an “average” via, but smaller vias can be specified. If you are unsure of the size you need, consult your PCB supplier. There are guidelines or specifications for both types of vias. You can also discuss the proper stacking of the board based on the technology.
Blind holes are usually created by drilling holes in one layer of the PCB. This drilling process is similar to the drilling process for through holes, but it uses mechanical drilling that interferes with the characteristics of the underlying board. On the other hand, laser drilling of blind holes goes through the outer layer. The outer layer of the PCB is not plated or etched during the drilling process.
