Blind Vias PCB By Type

ShengYi Blind Vias PCB (1)

It has been widely used in the consumer products and telecom sectors for over 10 years, and is now gaining popularity in other sectors such as medical, automotive & industrial.


Specially designed for the purpose of reducing the area of hole on the PCB. It can be used in a wide range of applications such as computer, communications, metering and power supply.

Multilayer Blind Vias PCB

Inner layers must have holes drilled or other features added without exposing the inner layers. Great way to reduce fabrication cost and increase your manufacturing efficiency.

Flexible Blind Vias PCB

Flexible Blind Vias for mounting surface-mount components onto a flexible substrate. It is a great way to mount components that cannot be mounted on rigid PCBs

Rigid Blind Vias PCB

Excellent choice to replace the previous conventional via hole. It can avoid the potential short circuit problems caused by two or more parallel wires contacted through via holes.

Rigid-Flex Blind Vias PCB

High performance, multi-layer flexible PCB system that combines the best characteristics of rigid and flex PCB technologies. Provides all the advantages rigid PCBs with the flexibility.

Blind Vias PCB by Types (5)

  • Tented Blind Vias PCB

    Tented Blind Vias PCB is a new design in the field of PCB industry. It utilizes a unique Via stacking technology, providing an unusual and creative solution for high density interconnect grounding.

  • Plugged Blind Vias PCB

    Great for use in any application requiring a simple and effective way to route the wiring between layers of the PCB. This is an easy solution for the circuit designer who needs an efficient way to route their wiring.

  • Filled Blind Vias PCB

    More advanced PCB than traditional non-filled vias as they both provide a connection (or pathways) from one layer to the next, however, traditional vias are open at the end whereas filled via are closed off at the end.

  • Covered Blind Vias PCB

    Used to connect two components on a circuit board without the need for a via hole. The via pad is covered with a plug, which is grounded and prevents the signal from escaping through the via hole in the circuit board.

  • Capped Blind Vias PCB

    Used for making electrical connections between two or more layers of a multilayer printed circuit board. Capped Blind Vias PCB design is the best for RF applications because it increases the conductivity.

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.

PCBTok’s Blind Vias PCB Advance Technological Process (1)

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.

OEM & ODM Blind Vias PCB Applications

Medical Equipment

Used in medical equipment because they allow the manufacturer to reduce costs and increase reliability by using fewer components, while still providing sufficient flexibility in design.

Industrial Control

They are used in industrial control applications to provide connectivity between layers of PCB without using a trace.

Military Technology

In the world of military technology, there are many processes that require a high level of precision and accuracy. It is essential that these processes are performed with the utmost care.

Smart Devices

Blind vias PCB for smart devices are used in the process of manufacturing smart devices. They are placed on the top side of the PCB and are not visible to the naked eye.


Perfect solution for your telecommunications PCBs. Blind vias allow you to route signals around obstacles, such as other components, without having to create a new connection through the board.

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.
