Here are at least four advantages of HDI PCB:

1. Achieving high path density with fewer layers, high assembly precision, small size as well as light weight, which meets the light and small size of electronic equipment.

2. With proper stackup resolution, HDI PCB also improves the power and signal integrity of PCB. At the same time, shielding layers of circuit and magnetic circuit are available;

3. Be conducive to mechanization and automated production, increasing labor productivity and reducing the cost of electronic equipment;

4. Simple installation and high reliability. Due to the high assembly density, the connection of each part (including components) is reduced.
