HDI MARKET REPORT OVERVIEW

global HDI market size was USD 20.63 billion in 2024 and market is projected to touch USD 55.08 billion by 2033, at CAGR of 6.1% during the forecast period.

High Density Interconnect (HDI) development is PCB one-piece technology with larger component density in less space than conventional PCB. Through proper application of the buried, blind and microvias, HDI boards may achieve finer lines and smaller vias, along with the higher density of connection pads, which in turn allows more components to be integrated into a small space. Configurations are covered from 1+N+1 to Ultra HDI, which covers design flexibility. HDI boards are compatible with various materials such as standard FR4, high-performance FR4 and Rogers substrates. Designers can thus achieve a compact and lightweight solution without sacrificing performance and functionality. This makes them suitable for applications that require miniaturisation and high-end electrical performance.

The upgrading of HDI technology with the latest technology brings great benefits. In the first place, it allows the creation of boards of smaller and fewer layers that can substitute several of the traditional boards in a particular product or board, leading to a successful design optimization and a lower weight and volume. Further, HDI enables perforation or penetration of extra features on both sides of the PCB which in turn intensifies the capacity utilization, proximity and placement of the components. Moreover, due to signal transmission heightened capabilities of high density interconnect boards, the signal loss and the time for cross-over are reduced significantly as a consequence of the decrease in the sizes of components and pitch feature and the result is better electrical performance.
