There are several important  reasons  in electronic manufacturing while using HDI PCB:

1.Miniaturization: HDI PCBs allow for miniaturization of electronic devices. As technology advances, electronic devices are becoming smaller and more compact, and HDI PCBs provide a way to fit more components in a smaller area.

2.Higher density: HDI PCBs offer higher density interconnects, which allow for more routing channels and signal paths. This is particularly useful in high-speed applications, such as in telecommunications and computing, where signal integrity and timing are critical.

3.Improved signal quality: HDI PCBs have shorter signal paths and less crosstalk, which leads to improved signal quality and reliability. This is especially important in applications where data transfer rates are high.

4.Reduced cost: HDI PCBs require less space, fewer layers, and less material than traditional PCBs. This reduces the cost of the PCB and allows for a more cost-effective design.

5.Increased reliability: HDI PCBs have a smaller form factor and a higher level of integration, which reduces the number of connectors and solder points. This results in fewer points of failure and increased reliability.

Overall, HDI PCBS are an essential component in electronic manufacturing as they offer significant benefits in terms of miniaturization, higher density, improved signal quality, reduced cost, and increased reliability.
