2021年12月3日 · An HDI PCB uses blind, buried, and micro vias, vias in pads, and very thin traces to pack more components into a smaller area. We’ll show you the design basics for HDI and how Altium Designer ® can help you create a powerful HDI PCB design .

2021年8月24日 · HDI PCBs, or microvia PCBs, feature blind microvias, fine traces, and sequential lamination manufacturing. This article introduces HDI PCB structure and manufacturing.

2024年11月4日 · Understanding HDI PCB Via Types: Microvias, Blind Vias, and Buried Vias. High-Density Interconnect (HDI) technology has revolutionized the printed circuit board (PCB) industry by enabling the design of more compact and efficient electronic devices. A critical aspect of HDI PCBs is the use of various via types, which facilitate electrical ...

High Density Interconnect (HDI) printed circuit boards (PCBs) are circuit boards with a higher wiring density per unit area than traditional PCBs. HDI PCBs have denser interconnections and components, finer lines and spaces, and higher connection pad density. They also have smaller vias and traces, and higher layer counts.

2025年3月13日 · One of the key innovations within HDI PCB design is the use of blind and buried vias, which enhance routing capabilities by freeing up additional routing resources, increasing the amount of routing channels while requiring fewer signal layers, and optimizing board space.

HDI boards, one of the fastest growing technologies in PCBs, are now available at Epec. HDI Boards contain blind and/or buried vias and often contain microvias of .006 or less in diameter. They have a higher circuitry density than traditional circuit boards.

3 天之前 · High-Density Interconnects (HDI) Blind and buried vias are foundations of high-density interconnects or HDI technology that supports modern electronics. They allow 15-20% higher routing density compared to traditional PCBs. Blind and buried vias further support multilayer stacking by allowing step-by-step layer addition, avoiding excessive ...

Vias are tiny conductive holes that connect multiple layers in a High Density Interconnect PCB and allows signals to flow through them easily. Depending on the functionality of a PCB, four different types of vias are drilled into an HDI PCB Layout, namely: Through Hole vias, Blind Vias, Buried Vias and Microvias.
