Background
The Printed Circuit Board (PCB) manufacturing process usually involves a back drilling process. Back drilling can be considered as a special depth control drill, namely: in the manufacture of the multilayer board, firstly, drilling a through hole and depositing copper once from the front surface to realize the electric connection of all layers; and then, secondary drilling (namely back drilling) is carried out on the through hole from the back by adopting a depth control drilling process, a back drilling hole with the aperture slightly larger than the through hole is drilled, and hole copper of a through hole section which does not need to be electrically connected is drilled.
In the back drilling process, the front and back drilling needs to be carried out twice, and whether the secondary drilling of the large hole and the primary drilling of the small hole are concentric becomes the key of the process. Since the back drill hole is very important for signal transmission, it is necessary to detect the concentricity and deviation between the back drill hole and the via hole, whether the hole is clogged with foreign matter, whether drilling is missed, and the like. Especially, in the circuit board in the industries of 5G and the like which are emerging at present, the process requirements for back drilling are more strict, and basically, products related to the back drilling process need to be fully inspected.
However, due to the special structure of the back drilling hole, the back drilling hole needs to be detected through equipment such as a hole site detector in the industry.
