HDI PCB Description

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.

The HDI PCBs we offer include the following characteristics:

1. Blind and/or buried vias

2. Via-in-pad

3. Through vias from surface to surface

4. Edge plating

5. Minimum track width and spacing in mass production in 4mil

6. Stacked micro vias

7. Countersunk holes or depth milling

8. Low-halogen material in standard and high Tg range
