High Density Interconnect Market Industry Trends Shaping Future Revenue Growth
Companies operating within the high-density interconnect (HDI) market are boosting their manufacturing capacities and introducing advanced HDI technologies to cater to the increasing demand for compact, high-performance electronic systems. HDI printed circuit boards are specialized PCBs characterized by finer lines, microvias, and high layer densities, which enable faster signal transmission, enhanced reliability, and miniaturized electronic designs. For instance, 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. This new facility will improve 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 for the manufacture of circuit boards with exceptionally fine feature sizes and superior electrical performance. This development solidifies TTM’s market position and supports the growing global demand for smaller, faster, and more efficient electronic devices.
