However, the market is restrained by high manufacturing costs, complex fabrication processes, and limited availability of advanced materials.
High Density Interconnect Market- Market Dynamics
Expansion of 5G networks and advanced communication infrastructure
5G technology operates at higher frequencies, including sub-6 GHz and millimetre waves, enabling faster data speeds, lower latency, and greater connectivity. This creates a critical need for advanced PCBs like HDI that can support these high frequencies with superior signal integrity, thermal management, and compact designs. HDI PCBs achieve this through microvias and fine traces, enabling miniaturised circuits with dense interconnections crucial for 5G smartphones, base stations, routers, and network equipment. The rapid rollout of 5G infrastructure globally, including in key markets such as the U.S. and India, intensifies HDI demand. According to data published in March 2025 by the Press Information Bureau, 5G services have been launched in all States and Union Territories across the country and are currently available in 773 of the 776 districts, including Lakshadweep. As of February 28, 2025, Telecom Service Providers (TSPs) have installed 4.69 lakh 5G Base Transceiver Stations (BTSs) nationwide. Therefore, the rapid expansion of 5G networks and advanced communication infrastructure is significantly boosting the demand for high density interconnect (HDI).
