What is an HDI PCB

What is an HDI PCB

HDI is an abbreviation for High-Density Interconnector. It refers to a printed circuit board with a higher wiring density per unit area than a standard board. HDI PCBs are characterized by finer spaces and lines, minor vias and capture pads, and higher connection pad density. These features help to improve the electrical performance and miniaturization in the weight and size of the board. A High-Density Interconnector PCB is best suited for the high-layer count and high-end laminated devices.  

Regarding the electrical requirements of super signal speeds, the board must have exceptional features, like high-frequency transmission capacity, impedance control, minimal redundancy radiation, and others. Additionally, the board should have an enhanced density due to component miniaturization. 

The components placement process should be done with extra precision than in standard boards because of the small pads and fine circuitry pitch. Again, lead-free chips require special soldering and additional assembly and repair steps. The small circuitry weight and size allow HDI PCBs to fit into small spaces in various electronic devices. The smaller weight and size further translates to minimal chances of experiencing mechanical shocks.

The Benefits of Using HDI PCBs

  • Better signal veracity. Since HDI PCBs integrate blind via and via-in-pad technologies, it puts the board components together without minimizing the signal length. Besides, HDI technology abolishes via stubs. This inhibits signal reflections and improves signal quality.  
  • Affordable. A typical 8-layer PCB can be modified to a 6-layer board without affecting its quality through HDI technology. This will save you a lot of resources. 
  • Compact designs. The classification of microvias, blind vias, and buried vias minimizes the need for more board space. 
  • High reliability. The integration of stacked vias creates a solid shield, making HDI PCBs highly resistant to harsh environmental conditions. 
  • Extraordinary adaptability. HDI technology is perfect for boards that seriously consider board space, weight, performance, and reliability as their main concerns.

The Difference Between Standard and HDI PCBs

Standards printed circuit boards use through-holes to achieve high stray capacitance and a colossal discontinuity in impedance. In a layman’s language, they boost an average signal integrity performance. On the other hand, HDI boards use buried and blind vias to reduce the stray inductance and capacitances. The outcome is a strong signal integrity performance. 

Other significant differences between standard and HDI boards include:

  • A standard PCB has a lower component density per square inch, while an HDI PCB has a higher component density per square inch. 
  • A standard board uses mechanical drilling, while an HDI PCB uses direct laser drilling. 
  • Standard printed circuit boards have heavier and larger boards, while HDI PCBs have lighter and smaller boards with augmented performance. 
  • A standard PCB has many layers, while an HDI PCB has few layers.
  • When a standard PCB is paired with a low pitch package, it experiences compatibility issues, while an HDI board works perfectly with both low and high packages.

HDI PCB Applications

HDI PCB Applications

High-Density Interconnector PCBs are applicable in various industries. As mentioned earlier, you will find them in all sorts of electronic gadgets, where miniaturization plays an essential role in the effective use of the product. HDI PCBs are also common in automobiles, aircraft, and other vehicles that heavily depend on electronics.   

One of the major industries where HDI boards are making massive exploits is the healthcare field. Medical equipment often requires small packages with super transmission rates, which only HDI boards offer. For instance, an implant should be small enough to fit in a human body, but all the equipment used in an implant must have high signal transmission capacities. In this case, the High-Density Interconnector boards make a good use case. These PCBs are also applied in other medical tools such as emergency room monitors, CT scans, and others.

No matter the industry you work in, HDI PCBs have the potential to enhance the electronics you deal with. Get in touch with us to discuss your requirements. We will advise you whether you are on the right track and help you exploit the benefits of HDI technology in your area of specialization.
