HDI PCB is among the fastest growing PCBs on the market because it meets complex design needs. This kind of high density interconnect printed circuit board allows designers to place more components in a smaller area. Having a higher circuitry density than conventional PCBs, it's able to incorporate finer lines and spaces, smaller vias & capture pads, and higher connection pad densities. It contains blind/buried vias and is often with 6 mil microvias.

HDI custom PCB is widely used to reduce the weight and overall dimensions of products, as well as enhancing the electrical performance of the device. It's regularly found in mobile phones, touch-screen devices, and 4G network communications.

   China Dragon offers HDI custom PCB fabrication with microvias down to 4 mil; laser drilling is required.
