The global high-density interconnect (HDI) PCB market size reached USD 9.1 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 13.9 Billion by 2033, exhibiting a growth rate (CAGR) of 4.59% during 2025-2033. The market is experiencing significant growth due to the rising demand for compact, high-performance electronics. Features like reduced size, enhanced electrical performance, and multi-layered structures make HDI PCBs crucial for smartphones, automotive, and medical devices. The innovations in miniaturization and high-speed data processing, is also contributing positively to the market growth.

Interconnecting printed circuit boards (PCBs) with high-density interconnects (HDIs) are circuit boards having a better wiring density per unit than conventional circuit boards. With blind and buried vias, it contains micro-vias that are smaller in diameter and have a relatively greater pad density than conventional circuit boards while having a higher circuitry density than traditional counterparts. High-density PCB technology has allowed engineers an enhanced design freedom and flexibility, thus allowing them to place smaller and closer components, which reduces signal loss and crossing delays. An interconnect PCB with high density gives designers more surface area to work with. As a result, high-density interconnect PCBs deliver better signal quality and faster signal transmission.
