HDI PCB (High-Density Interconnect printed circuit board) represents advanced PCB technology offering significantly higher wiring density than conventional circuit boards. According to IPC-2226 standards, HDI PCBs feature ultra-fine lines and spaces (≤100 µm), smaller vias (<150 µm), and enhanced connection pad density exceeding 20 pads per square centimeter. Using sophisticated micro-blind and buried via structures, HDI technology enables complex routing in compact spaces, making it ideal for modern electronic devices requiring high performance in smaller form factors.
Asunny’s goal is to enhance our partners’ supply chain by establishing long-term relationship and striving to be the most reliable PCB supplier. In the past three decades, we have proven our ability to achieve this goal.
Unlike most manufacturers who can only fabricate small to medium batch, we can actually manufacture HDI PCB in large batch. We can manufacture up to 3+N+3 and we are capable of making blind, buried and through-hole vias. Our HDI end clients include BYD, Xiaomi, Samsung and Honor etc.
Understanding the different HDI PCB stack-up structures allows designers to more easily assign layers, place components, and plan routing paths. This helps make the most of the available space and improves overall PCB layout efficiency. The diagram on the left shows the most common HDI stack-up structures.
Asunny offers HDI PCB fabrication services for various applications. From consumer electronics, AI applications, to industrial control and more.
