HDI PCBs

Compare to standard rigid PCB, HDI PCBs or high density interconnect PCBs require a much higher wiring and pad connection density. They are featured by finer trace and spacing, smaller capture pads, and micro-sized vias.

HDI PCBs are widely used for cell phone, tablet computer, digital camera, GPS and other different area. That’s because the market demand for lightweight and thinner PCBs which can handle high-speed signals with reduced signal loss has steadily increased, and compared to other PCBs, HDI can meet these requirements better.

Except the advantages of lightweight and steady high-speed signal, HDI PCBs also have the strengths in the following aspects. They are lower cost, better reliability, enhanced wiring density, improved design efficiency and thermal properties, advanced packaging technology, better electrical performance and signal correctness, improved frequency interference radio, electromagnetic interference and electrostatic discharge.
