HDI PCBs are the PCB 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. With the development of the electronic market, there are a big grown with the HDI PCBs, Polaris can provide high quality HDI PCB service with the support of the top technology from the factory engineers.
