How to define the order of PCB blind buried holes?
In the electronics manufacturing industry, the printed circuit board (PCB) is an important component, and its design and manufacture have a significant impact on the performance of the entire electronic device. Blind and buried vias are a common design element in PCB design, and they play a key role in improving PCB performance and saving space. However, how to define the order of PCB blind and buried vias may still be a question for many people. This article will explain in detail the definition of the order of PCB blind buried holes, and discuss its importance in practical applications.
In PCB design, a blind buried via is a hole that starts from one side of the PCB but does not penetrate to the other side. This design can effectively save PCB space and improve its performance. The buried hole is the connection between the inner layers and does not lead to the outer layer. So, how is the order of PCB blind buried holes defined? In simple terms, the order refers to the number of layers through which the blind buried via passes. For example, if a blind buried via penetrates from the first layer to the third layer, then we say that the blind buried via is third-order. Likewise, if a blind buried via penetrates only one layer, it is first-order.
After understanding the definition of the order of PCB blind buried holes, we can better understand its importance in practical applications. First, by using blind and buried vias of different orders, designers can use PCB space more effectively and improve its performance. Secondly, blind and buried vias of different orders can also meet different electrical performance requirements. For example, high-order blind and buried vias can provide better electrical connection performance.
In general, the definition of PCB blind buried hole order is an important concept, which plays an important role in understanding and optimizing PCB design. By understanding and applying this concept, designers can better design and manufacture high-performance PCBs that meet the needs of various electronic devices.
