What Is an HDI PCB? Microvias, Density, and High-Speed Performance
WHAT THIS VIDEO COVERS
This video delivers a focused engineering overview of HDI PCBs, also known as high-density interconnect boards. It explains how microvias, fine lines, and thin dielectrics enable significantly higher component counts and I/O density without increasing overall board size. Viewers learn how these features support faster signal transmission, reduced crosstalk, and improved electrical performance in high-speed designs.
Manufacturing techniques such as sequential lamination and laser drilling are covered for achieving precise multilayer structures. Real-world applications include smartphones, tablets, medical devices, and aerospace systems where compactness and reliability are critical. The video also details our fabrication capabilities, including up to 20-layer HDI boards, stacked and staggered microvias, controlled impedance routing, and advanced surface finishes.

FAQ
Q1: How do microvias improve signal integrity and speed in HDI PCBs compared to standard vias?
A1: Microvias improve signal integrity and transmission speed by shortening electrical paths, reducing parasitic inductance and capacitance, and minimizing signal loss and crosstalk compared to traditional through-hole vias. Their smaller size also enables denser routing and better performance in high-speed, high-frequency PCB designs.
Q2: What is the maximum layer count and microvia configuration supported for HDI PCB fabrication?
A2: The HDI PCB fabrication capabilities support up to 20-layer boards with both stacked and staggered microvia configurations, along with controlled impedance routing and advanced surface finishes.
Q3: Which compact high-performance applications benefit most from HDI PCB technology?
A3: HDI PCB technology is widely used in compact, high-performance applications such as smartphones, tablets, medical devices, aerospace electronics, and other miniaturized systems requiring high component density, fast signal transmission, and reliable multilayer interconnections.
