Blind Via Hole
In a complex multilayer board, part of the through holes are deliberately not fully drilled because only a few layers of interconnection are needed. If one of the holes is connected to the hole ring of the outer board, this special hole, such as a cup-shaped blind alley, is called a "blind hole" (Blind Hole).
