HDI PCB and Microvia

  • HDI PCBs, or microvia PCBs, are high-density-interconnect printed circuit boards with blind microvias, fine traces, and sequential lamination structures. HDI PCBs usually have a horizontally symmetrical structure. Besides blind vias, HDI PCBs often have buried microvias. Generally, we distinguish HDI PCBs by the number of lamination cycles and laser drill pairs that are required. For example, 3+N+3 means the HDI PCB requires three times laser drilling and laminations.
  • Microvias can only be laser drilled and has an aperture of 6mil and below. In HDI PCBs, microvias can be single, staggered, stacked, and skipped. The smaller microvia aperture, the smaller parasitic capacitance, and it is more practical for high-speed circuits.

HDI PCB Lamination

HDI PCB manufacturing process
A microvia penetrates only one PCB layer, and the number of microvia pairs stands for how many times of lamination in HDI PCB manufacturing.
The internal layers without microvias are laminated in the standard lamination way under high temperatures and high pressure. Prepreg melts, fills in gaps between adjacent copper layers, and cures so that the copper layers are bonded and insulated.
Lamination to external layers with microvias is more difficult than internal layers. Microvias are laser dilled before lamination, and after lamination, microvias on different layers may overlap to form stacked vias or stagger to form staggered vias. Positioning for laser drilling and lamination should be highly accurate. Otherwise, the board defects. So HDI PCB manufacturing costs more than normal PCBs.

Advantages of HDI PCBs

  • HDI PCBs are suitable for products where electrical performance and noise rejection are of utmost importance. The advantages of HDI PCBs include:
  • ● HDI technology decreases products' overall size and improves electrical performance.
  • ● HDI PCBs have great impedance control and impressive high-frequency transmission capabilities.
  • ● HDI PCBs offer a perfect solution for fine pitch packages, flip-chip assemblies, and complicated BGA designs.
