Product Detail

What is HDI PCBs?

High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the printed circuit board market. Because of its higher circuitry density, the HDI PCB design can incorporate finer lines and spaces, smaller vias and capture pads, and higher connection pad densities. A high-density PCB features blind and buried vias and often contains microvias that are .006 in diameter or even less.

1.Multi-step HDI enables the connection between any layers;

2.Cross-layer laser processing can enhance the quality level of multi-step HDI;

3.The combination of HDI and high-frequency materials, metal-based laminates, FPC and other special laminates and processes enable the needs of high density and high frequency, high heat conducting, or 3D assembly.
