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. 

What is an HDI PCB

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 High-Density Interconnector Circuit Boards 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 High-Density Interconnector PCBs


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.  


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. 


The classification of microvias, blind vias, and buried vias minimizes the need for more board space. 


The integration of stacked vias creates a solid shield, making High-Density Interconnector PCBs highly resistant to harsh environmental conditions. 


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.


Applications of High Density Interconnector (HDI) PCB

✔️  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. It is 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 PCB 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.
