8-layer ENIG HDI PCB High Component Density For 5G Communication Equipment

♦ What is HDI PCB?

HDI (High Density Interconnect) PCB is a high-density circuit board constructed by micro blind buried via technology, and uses a build-up process to achieve three-dimensional interconnection of inner and outer layer circuits. The core of its manufacturing lies in the use of laser drilling and electrochemical hole filling processes to form micron-level conductive paths between layers, so that each layer of circuit can be vertically connected without relying on traditional through holes. Ordinary HDI uses a single-layer structure, while high-end products are stacked through multiple layers, combined with advanced technologies such as stacked holes and laser direct forming, to further improve circuit density and electrical performance.

♦ Characteristics of HDI PCB

• • High circuit density
  • Miniaturization and thinness
  • Excellent signal integrity
  • Good heat dissipation performance
  • High reliability
  • A variety of laminate structures are available

♦ Applications of HDI PCB

• • Consumer electronics: used in smartphones, tablets, smart watches, etc. to achieve thinness and high performance of devices. For example, a mobile phone motherboard adopts HDI design to reduce size, improve performance and stability.
  • Communication field: It is a key component of 5G base stations, satellite communications, optical fiber communications and other equipment to ensure high-speed and stable signal transmission. For example, NVIDIA's GB200NVL72 system achieves a transmission rate of 1800Gbps.
  • Automotive field: used for autonomous driving, in-car entertainment, body control, power systems, etc., to meet the complex environment requirements of automotive electronics and improve automotive intelligence and safety. For example, automotive electronic modules need to be resistant to high temperatures and shockproof, which can be met by HDI PCB.
