HDI PCB in computers is a high-density interconnect circuit board that is commonly used in complex electronic devices such as smartphones, tablets, and computers.
HDI PCB circuit boards use a series of advanced manufacturing technologies, such as micro-wires, blind buried vias, buried resistors and inter-layer interconnections. These technologies enable HDI PCBs to achieve higher connection density and more complex circuit designs in a relatively small size.
Due to the manufacturing process of HDI PCB circuit boards and the high precision requirements required, the manufacturing cost of HDI PCBs is usually higher compared to traditional ordinary circuit boards. Specific cost factors are also affected by many other factors, such as the number of layers required, line width/space, aperture requirements, etc.
