HDI PCBs are circuits that offer much higher wiring densities per area than standard circuit boards, with finer lines and spaces, smaller vias and higher connection pad density. This technology allows you to reduce the size and weight of your components while simultaneously enhancing performance.
As one of the fastest growing technologies in PCBs area, HDI PCBs are now at Hampoo contain blind and/or buried vias, laser microvias in a wide range of industry. Our HDI PCB service market includes Telecom, Medical, Military, Aerospace , Supercomputing etc.
