What Is Covered Under High Density Interconnect Market?

High-density interconnect (HDI) is a printed circuit board (PCB) that enables placing more components on the same board space. It is used to reduce the size of the PCB while adding more functionality and features to a single board. The main types of high-density interconnect are single panels, double panels, and others. A single panel is a type of PCB construction in which all of the electronic parts and circuitry reside on a single layer of the board. These panels are employed when the individual board size is substantial. Assemblies of low-volume boards also employ it. They are made of rigid, flexible, and rigid-flex substrates for automotive, consumer electronics, telecommunications, medical, and other end-users.

What Is The High Density Interconnect Market Growth Forecast?

The high density interconnect market size is expected to see rapid growth in the next few years. It will grow to $28.82 billion in 2030 at a compound annual growth rate (CAGR) of 10.3%.
