With this article and some others that will follow later we would like to share available knowledge in the PCB design and manufacturing field.
Following some articles related to HDI PCBs we would like to describe the three related more common build-up structures.
HDI PCB types
The design designation system of this standard recognizes industry approved design types used in the manufacture of HDI printed boards. The designations determine the HDI design type by defining the number and location of HDI layers that may or may not be combined with a substrate.
