HDI PCBs are the cream of the crop in the PCB world, characterized by their high density of components and conductor patterns. This is achieved using finer lines and spaces, smaller vias and capture pads, and higher connection pad densities than found in conventional PCBs. The essence of HDI technology lies in its ability to pack more functionality into a smaller space, making it a perfect match for the compact and complex designs demanded by wearable electronics.
