HDI PCB Technology and Benefits

Blind Buried Circuits offers advanced design and manufacturing solutions to achieve high-density interconnections. The design incorporates multiple layers of conductive material and vias, increasing routing density using micro, buried, and blind vias. This complex technology enables the interconnection of complex circuitry in smaller areas. The following are the benefits of HDI PCB technology:

  1. Most mobile technology, such as smartphones and tablets, are manufactured using HDI technology. As mentioned before, it helps miniaturize electronic devices, making them more portable and lightweight for the consumer. 
  2. HDI PCBs are manufactured with shorter trace and spacing to maintain electromagnetic interference to improve signal integrity, resulting in better electronic system performance and reliability.
  3. HDI PCB facilitates data transmission at a higher speed for higher-speed designs and enables the designs to give faster outputs. 

HDI PCB vs Traditional PCB

There is no comparison of HDI PCB vs Traditional PCB, as HDI PCBs are the better version of Traditional PCBs. Due to the limitation of routing density and interconnection capabilities of traditional PCBs, they are suitable for simple electronic designs with fewer component placements and interconnections. However, HDI PCBs enable greater design flexibility and complex circuitry. 

HDI PCB Advantages

Blind Buried Circuit manufacture all type of HDI PCBs. The following are the advantages of HDI PCBs:

  1. Increased component density: For compact electronic devices, the circuits require a large number of components in a limited area. HDI PCBs can accommodate complex designs in limited areas.   
  2. Better signal integrity: For high-speed boards, signal loss and electromagnetic interference play a vital role in the functionality. HDI PCBs provide better reliability and performance for signal integrity circuit designs. 
  3. Improved thermal management: With the help of better routing density, the HDI circuit designs provide optimal head dissipation and better functioning of electronic components. 
  4. Higher interconnection reliability: using the blind buried vias technology in the HDI PCB designs ensures strong multiple-layer connections and reliable manufacturing between conductive layers.
