PCB boards typically have a multi-layer board structure where in the fabrication of multi-layer boards, e.g. 12-layer boards, we need to connect layer 1 to layer 9, typically we drill through holes (one-pass) and then copper is deposited. Thus, layer 1 is directly connected to layer 12, and in practice we only need layer 1 to layer 9, layers 10 to 12 are like a column because there is no wiring connection. This post affects the signal path and can cause signal integrity problems in the communication signal. This extra post (known in the industry as a STUB) is drilled off the back (secondary drill), called the backdrill. But need to clean the dust in the hole after back drilling, at present, the cleaning is carried out manually, which wastes manpower.
