Introduction to HDI
High – Density Interconnect (HDI) technology is a key innovation in the field of printed circuit boards (PCBs). HDI PCBs feature finer lines and spaces, smaller vias, and higher connection densities compared to traditional PCBs. This technology allows for more components to be placed on a smaller board area, enabling the development of smaller, lighter, and more powerful electronic devices. HDI technology is widely used in various industries such as smartphones, tablets, wearables, and high – end medical devices. HDI
