The increasing application of the automotive industry is expected to drive the growth of the high-density interconnect (HDI) market in the coming years. The automotive industry encompasses a wide range of organizations involved in the design, development, manufacturing, marketing, sale, and maintenance of motor vehicles. HDI technology offers numerous advantages for the automotive sector, including enhanced performance, improved reliability, better signal transfer, miniaturized components, and cost efficiencies. For instance, in March 2025, the European Commission, the executive body of the European Union, reported growth in new passenger vehicle registrations, with battery electric vehicle (BEV) sales increasing by 27.7% and accounting for over 13% of total sales for the year. The Commission plans to strengthen autonomous vehicle regulations and, in collaboration with private partners, invest approximately USD 1.16 billion (€1 billion) by 2027. Therefore, the expanding automotive sector is driving the HDI market.
Major companies in the HDI market are expanding manufacturing capacities and introducing advanced HDI technologies to meet the growing demand for compact, high-performance electronic systems. HDI printed circuit boards are specialized PCBs that feature finer lines, microvias, and high layer densities, enabling faster signal transmission, improved reliability, and miniaturized electronic designs. For example, in February 2025, TTM Technologies Inc., a US-based leading PCB manufacturer, announced the expansion of its Ultra-HDI PCB production facility in Syracuse, New York. The facility enhances TTM’s capability to produce next-generation Ultra-HDI boards for applications such as 5G infrastructure, artificial intelligence hardware, and advanced automotive electronics. The expansion incorporates state-of-the-art laser drilling, sequential lamination, and imaging technologies, allowing production of circuit boards with extremely fine feature sizes and improved electrical performance. This development strengthens TTM’s market position and supports the growing global demand for smaller, faster, and more efficient electronic devices.
In October 2024, DuPont, a US-based provider of advanced HDI and thermal management solutions, partnered with Zhen Ding Technology Group for an undisclosed amount. The partnership aims to jointly advance high-end PCB technology, enhance end-user applications, and improve material performance. Zhen Ding Technology Group is a China-based company specializing in the design, development, and manufacturing of printed circuit boards (PCBs).
