What is Flexible PCB?
A High-Density Interconnect Printed Circuit Board is a type of printed circuit board specially engineered for miniaturized and high-speed electronic products. As an advanced printed circuit board solution provided by an HDI PCB supplier and manufacturer, the HDI PCB uses fine traces, small vias, and multilayer construction to achieve high efficiency and minimize the size of the board.
When compared to regular printed circuit boards, HDI boards provide improved wiring density and increased signal performance by utilizing technologies such as microvias, fine lines, and multilayers.
