The high density interconnect market encompasses advanced PCB constructions utilizing laser-drilled microvias, sequential lamination build-up layers, and fine line/space patterning to achieve wiring densities exceeding conventional through-hole and standard multilayer board technology. Product tiers span 4 to 6 layer sequential build-up, 8 to 10 layer stacked microvia, and 10+ layer any-layer interconnect constructions. FMI is of the opinion that the market is driven by the parallel demand pressures of automotive electronics content growth and smartphone motherboard miniaturization, both of which require interconnect density improvements that only HDI technology can deliver within the physical constraints of modern electronic device architectures.
Market scope covers 4 to 6 layer, 8 to 10 layer, and 10+ layer HDI PCBs manufactured using laser-drilled microvias, sequential build-up lamination, and fine line/space patterning for automotive, computing, communications, financial services infrastructure, connected devices, and wearable electronics applications.
Conventional through-hole PCBs without microvia or sequential build-up technology, single and double-sided PCBs, and flexible printed circuits (FPC) without HDI layer construction are excluded.
The factors restraining the growth of the high density interconnect market are the high cost and limited application areas. High production expenses are experienced due to this technology's need for sophisticated manufacturing processes and expensive materials. Traditional PCBs are less sophisticated than high density interconnect technology, necessitating specialist design, and manufacturing knowledge. Its acceptance in quick-paced sectors is constrained by its complexity. This can also lead to lengthier development durations and thus restrain market growth.
The designs and production methods used by several firms to create high density interconnect technology are exclusive.
Due to this, competition is restricted, and it is challenging for new competitors to enter the market which restrains the market growth. Often exclusive, high-end applications like smartphones, tablets, and other portable electronic devices typically utilize high density interconnect technology.
