Detailed Product Description

What Are High-Density Interconnect PCBs?

High-Density Interconnect (HDI) PCBs utilize advanced printed circuit board (PCB) manufacturing technology to achieve higher wiring density, smaller size, and enhanced functional integration. By utilizing microvias, blind vias, buried vias, and more sophisticated circuit designs, HDI significantly improves circuit connectivity per unit area and is widely used in modern electronic devices with extremely high space, performance, and reliability requirements.



HDI PCB Features:

  • High-density interconnection
  • Micro via
  • Blind and buried hole design
  • Multi-level design
  • Fine lines and fine pitch
  • Excellent electrical performance
  •  Highly integrated


Manufacturing process:

  • Microvia technology: One of the key technologies of HDI PCB is microvia technology, which uses laser or mechanical drilling to create tiny holes (gener less than 0.2mm) on the circuit board, and these microvias are used to achieve connections between layers.
  • Multilayer wiring: HDI PCBs typically employ a multilayer design, connecting different circuit layers through blind and buried vias. Interconnection each layer is achieved through microvias, blind vias, or buried vias, which enhances the density and integration of the circuit board.
  • Blind and buried via design: Blind vias are holes that connect only the outer and inner layers, while buried vias are holes that connect the inner layers. The use of these holes can further reduce the volume of the circuit board and increase the wiring density.
  • Surface treatment and assembly: The surface treatment of HDI PCBs requires higher precision and reliability. Common surface treatments include HASL, OSP ,ENIG(Organic Metal Surface Treatment), etc. In addition, the assembly process of HDI PCBs usually requires fine welding technology to ensure the close connection between and the circuit board.
  • High-precision process: In the manufacturing process of HDI PCB, high-precision etching technology is required to ensure the correct manufacturing of fine lines precision holes. At the same time, it is necessary to precisely control variables such as current density, temperature, and pressure to ensure the consistency and high performance.
