High-Performance HDI PCB Manufacturing

Advanced solutions for compact, high-speed, and reliable electronics.

At Wonderful PCB, we specialize in manufacturing High Density Interconnect (HDI) PCBs with precise multilayer structures, microvia technology, and advanced materials to meet the demands of modern electronic products.

Common Buildup Structure

The difference between HDI PCB and ordinary PCB, you can see from the Buildup Structure.

HDI PCB vs. Traditional PCB

Feature / Parameter	HDI PCB (High Density Interconnect)	Traditional PCB
Line/Space	As low as 50 μm (0.05 mm)	Typically ≥ 100 μm
Via Technology	Microvias, blind vias, buried vias, via-in-pad	Through-hole vias only
Layer Count	Up to 20+ layers with compact design	Usually up to 8–12 layers
Density	High component density, compact design	Lower density, larger board size
Signal Integrity	Better performance for high-speed & RF circuits	More signal loss and crosstalk
Size & Weight	Smaller, lighter, space-saving	Larger and heavier
Design Flexibility	Allows advanced stack-ups (1+N+1, 2+N+2, any-layer)	Limited stack-up options
Applications	Smartphones, tablets, medical devices, automotive, aerospace	Consumer electronics, industrial equipment, home appliances
Manufacturing Cost	Higher (advanced process required)	Lower
Reliability	High reliability, especially for portable and high-frequency devices	Standard reliability
