HDI printed circuit boards are commonly found in complex electronic devices that require superior performance while saving space. Applications include mobile/mobile phones, touch screen devices, laptops, digital cameras, 4/5G network communications and military applications such as avionics and smart munitions.

One of the fastest growing technologies in printed circuit boards, HDI boards contain blind and/or buried holes, often containing microholes with a diameter of 0.006 or less. They have a higher circuit density than traditional circuit boards.
