HDI PCB–高密度相互接続PCB
HDI boards, short for High-Density Interconnects, are high-density printed circuit boards manufactured using micro-blind/buried-via technology and stacked-layer processes. This results in more compact circuits, faster signal transmission speeds, and a complete revolution in the design and manufacturing of electronic devices. HDI boards can integrate more functions in a smaller space, making devices thinner, lighter, and more efficient. They are core components of high-end electronic products such as mobile phones, 5G devices, and automotive electronics.
