blind via pcb
1. What is a blind via PCB
Blind via PCB technology is a technology widely used in the design and manufacture of printed circuit boards (PCBs), and its main purpose is to achieve higher circuit density in a limited space.
Blind vias refer to holes that extend from the surface layer of a PCB to the internal layer but do not penetrate the entire board.
This design enables the circuit board to achieve more complex circuit connections without increasing the number of layers, thereby improving the performance and functionality of the circuit board.
2. The principle of blind via PCB
The principle of blind via PCB is to establish an electrical connection between the surface layer and the internal layer of the PCB without penetrating the entire board.
This design not only saves space, but also reduces the path of signal transmission, thereby improving signal integrity and transmission speed. The manufacturing process of blind vias usually includes laser drilling and electroplating filling, which ensure the accuracy and reliability of blind vias.
