Benefits of PCB HDI Technology

The features of HDI boards is the fact that they allow for higher circuit density than a traditional circuit board. With concentrated arrangement of small components, what it creates are concise pathways. Additionally, these PCBs are known by their smaller buried and blind vias as also laser drilled microvias, which are far more effective in terms of space. What the reduced size of components paced close together, means is that there is quicker signal transmission and a marked decline in signal loss.

Some of the other benefits of HDI PCBs include

  • First and foremost, they are known for their compact size. The boards offer the ability to place components on both sides of the raw PCB through a blind and buried vias and via-in-pad technology. In fact, their HDI capacity makes sure that a 10 layered PCB can be turned into as much as a four or five layered one. What you have, in turn, are small boards without any compromise on quality.
  • What these compact boards come with, is improved electrical performance as there is a short distance between components and a higher number of transistors. All of this results in low power consumption and improved signal integrity.
  • HDI Boards also turn out to be a far more cost-effective option than regular boards as they come with lower number of layers.
  • HDI boards also lend themselves to quick production times. This is made possible because not only it is easy to place the components and via, but also the time for testing is lower. In turn, what this means for you, is quicker time-to-market.
  • Overall, what you get by way of HDI boards is, therefore, increased reliability.
