HDI PCB, the full name of High Density Interconnection printed circuit board, is a type of surface mount PCB. It has the characteristics of high density, fine pitch, high reliability, etc., and can be used in the production of multi-layer boards. The design of HDI PCB mainly focuses on the realization of high density, high precision, high reliability, and the realization of maximum wiring in limited space.
HDI PCB design needs to follow certain design rules and standards, such as using smaller apertures and thinner board thicknesses, using blind via and buried via technologies, etc.
At the same time, HDI PCB design also needs to consider factors such as signal integrity and power supply stability to ensure product reliability and stability.
