The Rise of High Density Interconnect PCBs

Nowadays, High Density Interconnect (HDI) printed circuit boards (PCBs) are being used increasingly. These PCBs incorporate higher connection pad densities, finer lines and spaces, and smaller vias and capture pads. Electronics industry has made a lot of technological advancements, thanks to high density interconnect PCBs.

What are the Benefits of HDI PCBs?

There are a number of benefits of using the HDI PCBs in various applications. Here are some benefits:

1. Exceptional Versatility: The high density interconnect circuit boards are typically used in applications in which weight, space, reliability, and performance are major concerns. Thus, HDI circuit boards are used in a wide range of applications that are related to aeronautics, consumer products, electronics, and computers.
2. Compact Designs: These high density boards make use of either blind vias, buried vias, or a combination of both. At times, these circuit boards also integrate microvias, which have extremely small diameter. Hence, less space is sufficient to incorporate more components.
3. Higher Reliability: The multilayer high density interconnect boards have a capacity to offer solid interconnection of stacked vias. This makes them highly reliable for use in most extreme and unfavorable environments.
4. Improved Signal Transmission: HDI printed circuit boards make use of small components. These circuit boards incorporate via in pad and blind via technology, and thus allowing components to be placed closer to each other. This helps in reducing signal losses and the possibilities of cross delays, thereby improving the signal transmission rates. All these things help improve the overall performance of the high density interconnect printed circuit boards.
5. Cost-effective Designs: High density circuit boards help in reducing the size of products, without compromising on their quality. Hence, with the help of HDI technology, an 8 layer through-hole PCB can be reduced to a 4 layer HDI microvia PCB. However, the wiring capabilities of the 4 layer HDI PCB have the same or better function as that of an 8 layer PCB. A high-quality HDI design can be availed at cost effective prices.

Where are HDI PCBs Used?

The benefits explained above make these PCBs suitable for use in a number of applications, which include:

1. Medical Equipment: The use of HDI printed circuit boards with advanced software in domestic and monitoring equipment has made these equipment to become more reliable. The technology has added more technical features to these equipment, and thus allowing them to aid medical teams with patient treatments.
2. Aerospace: Aerospace applications require PCBs, which are light weight and consume less space. Both these requirements are fulfilled by using high density interconnect circuit boards.
3. Computers and Smartphones: Smartphone and computers used today demand reduced weight, and smaller profiles, along with increased functionality. These demands can be easily achieved with the help of high density interconnect PCBs. This makes these PCBs a preferred choice in computers and smartphones.
4. Military: Several devices used in military communication, as well as other strategic equipment make use of HDI PCBs for a better performance.

The above-mentioned are just a few applications of HDI PCBs. They are used in several other applications, apart from those explained above. These high density circuit boards are therefore, becoming increasingly popular because of the several benefits they have.
