Top pcb board wiring length is short, low impedance circuit, high-frequency high-speed work, stable performance, can take on more complex function, is to the high frequency electronic technology, multi-function large capacity development inevitable trend.In particular, the in-depth application of large-scale integrated circuits will further drive PCB to high precision and high level.

The technical difference of HDI is reflected in the increment stacked number, the more layer quantity, the more difficult the technology.HDI can be divided into single stacked HDI, doule stacked HDI, triple stacked HDI,or high stacked HDI, etc., the number of layers is expressed as C+N+ C, where N is the number of normal core laminar, and C is the number of added layers, namely the stacked number of HDI..High stacked HDI cabling has higher density, but at the same time, it has more pressure, such as position, punch hole and copper plating, etc., which has higher requirements on the technical process and process capability of the manufacturer.
