Ordinary PCB refers to the signal frequency above 1GHZ bai. HDI PCB means that the vias in the multilayer board du have buried holes and blind holes.
HDI is the abbreviation of High Density Interconnector. It is a kind of technology for producing printed dao boards. It is a circuit board with high line distribution density using micro-blind buried hole technology. HDI is a compact product designed for small capacity users. It adopts modular and parallel design, with a module capacity of 1000VA (height 1U), natural cooling, can be directly put into a 19" rack, and a maximum of 6 modules can be connected in parallel.
The product adopts full digital signal process control (DSP) technology and a number of patented technologies. It has a full range of load capacity and strong short-term overload capacity. It can ignore the load power factor and crest factor.
HDI is the abbreviation of High Density Interconnector. High-density interconnect (HDI) manufacturing is a printed circuit board. The printed circuit board is a structural element formed by insulating materials supplemented by conductor wiring.
