HDI (High Density Interconnects PCBs) are used to meet market demand for complex designs in smaller form factors in most market segments (such as wireless, telecommunications, military, medical, semiconductor and instrumentation). The advantages of HDI PCBs are many, starting with more interconnects in smaller areas. The result is a miniaturization of the boards that can be used in many applications.
What is HDI PCBs?
The HDI PCB is the short form of high density interconnects
PCBs. It has been constructed using HDI technology for a compact and reliable
PCB design.
It features high-density attributes, including laser
micro-via, fine lines and high-performance materials.
Conventional PCBs are coated with copper in the inner and
outer layers, or like HDI PCBs are incorporated with stacked micro-via-filled
multi-copper layers. Components are placed closer together and space on the
board is significantly reduced, but functionality is not compromised.
This creates a structure allowing complex interconnections to
provide the necessary routing solutions.
High-tech applications use the advantages of HDI PCBs to
build high pin count chips.
