What is an HDI PCB?

HDI (High Density Interconnect) PCB is a type of printed circuit board featuring:

• Microvias (laser drilled)
• Fine line width/spacing
• High layer count & density
• Sequential lamination technology

Compared to traditional PCBs, HDI boards provide:

• Higher routing density
• Better electrical performance
• Reduced size and weight

Ideal for modern compact electronics.
