HDI PCB – High Density Interconnect PCB

High Density Interconnects (HDI) are used to meet the market demand for complex designs in smaller form factors across the majority of market segments, (Wireless, Telecom, Military, Medical, Semiconductor, and Instrumentation).

HDI Circuit boards, one of the fastest growing technologies in PCBs, HDI Boards contain blind and/or buried vias and often contain microvias of .006 or less in diameter.

They have finer lines and spaces always = <3mil They have a higher circuitry density than traditional circuit boards.
