         HDI PCBs play an important role in modern electronic devices. Its high device integration, small size, and high performance make it one of the top choices for high-end electronic products such as smartphones, tablets, laptops, digital cameras, and medical devices. With the continuous development of technology, HDI PCBs will continue to drive innovation and development in electronic devices, meeting people's demand for more advanced, miniaturized, and high-performance electronic products.
        HDI PCB (High Density Interconnect Printed Circuit Board) is a high-density interconnect printed circuit board designed to meet the demands of modern electronic devices for miniaturization, lightweight, and high performance. Compared to traditional printed circuit boards, HDI PCBs adopt advanced design and manufacturing technologies, enabling higher device integration and more connection points in a relatively small space.
         Firstly, HDI PCB adopts a multi-layer wiring design, which effectively improves the line density by implementing multi-layer circuits on the same layer. This means that more electronic components can be accommodated on circuit boards of the same size, thus achieving more complex circuit functions. Compared with traditional multi-layer printed circuit boards, HDI PCBs have higher device integration at the same size, enabling more complex electronic product designs.
          Secondly, the HDI PCB adopts Microvias technology. A micro hole is a very small hole used to transmit signals or connect electronic components between different layers. Compared to traditional holes, micro holes are smaller and denser, allowing for more complex wiring and connections on printed circuit boards, while reducing the size and weight of the circuit board.
          Finally, the HDI PCB adopts a precise manufacturing process. Due to the particularity of micro holes and high-density wiring, the manufacturing process of HDI PCBs requires higher precision and technical requirements. Manufacturers need to use advanced equipment and processes to ensure the quality and reliability of circuit boards. This includes steps such as imaging, chemical etching, coating, and copper plating to ensure that every detail of the circuit board meets the design requirements.
