High density interconnect PCBs are a way of making more room on your PCB to make them more efficient and allow


for faster transmission. It’s relatively easy for most enterprising companies that are using printed circuit boards to


see how this can benefit them.


High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the PCB market. Because


of its higher circuitry density, the HDI technology can incorporate finer lines and spaces, smaller vias and capture


pads, and higher connection pad densities. A high-density PCB features blind and buried vias and often contains


microvias that are .006 in diameter or even less

Key HDI PCB Benefits


The evolution of PCB HDI technology has given engineers greater design freedom and flexibility than ever before.


Designers using HDI high density interconnect methods now can place more components on both sides of the raw


PCB if desired. In essence, an HDI PCB gives designers more space to work with, while allowing them to place


smaller components even closer together. This means that a high-density interconnect PCB ultimately results in


faster signal transmission along with enhanced signal quality.


HDI PCB is widely used to reduce the weight and overall dimensions of products, as well as to enhance the electrical


performance of the device. The high-density PCB is regularly found in mobile phones, touch-screen devices, laptop


computers, digital cameras and 4G network communications. The HDI PCB is also prominently featured in medical


devices, as well as various electronic aircraft parts and components. The possibilities for high-density interconnect


PCB technology seem almost limitless.


HDI PCB Applications


HDI boards are appropriate for a wide range of industries. As mentioned above, you’ll find them in all types of digital


devices, like smartphones and tablets, where miniaturization is key to the effective application of the product. You can


also find high-density interconnect PCBs in automobiles, aircraft and other vehicles that rely on electronics.


One of the most critical areas where the high-density PCB is making huge inroads is in the medical arena. Medical


devices frequently need small packages with high transmission rates that only HDI PCBs can supply. For example,


an implant needs to be small enough to fit in the human body, but any electronics involved in that implant absolutely


must efficiently allow for high-speed signal transmission. Here, the HDI PCB indeed is a godsend. HDI PCBs can also


be useful in other medical equipment, like emergency room monitors, CT scans and much more.


No matter your industry, you’re probably already getting some ideas about how high-density interconnect PCBs can


make the electronics you produce or use even better – get in touch with us PCBCart to discuss it. We’ll let you know


if you’re on the right track and help you decide exactly how beneficial an HDI PCB can be to your industry. Then, you


can determine whether or not to take the next step.
