Abstract: A back drilling processing method for a circuit board includes: obtaining a board to be back drilled, wherein the board includes a target signal layer and at least two conductive reference layers; drilling a through hole at a set position of the board, and obtaining an actually measured spacing between two conductive reference layers; in response to a hole to be back drilled being of a first type, determining a target back drilling depth; controlling a drilling bit to drill for the target back drilling depth towards the target signal layer; in response to the hole to be back drilled being of a second type, determining a target relative height of a back drilling end point relative to a machine; and controlling the drilling bit to drill for the target relative height towards the target signal layer. The back drilling does not drill through the target signal layer.

Abstract: This application provide a method of processing a process in a container. The method is used in a physical machine, multiple containers are deployed on the physical machine, the physical machine includes a watchdog drive, and the method includes: receiving, by the watchdog drive, a first operation instruction of a first container by using a dev which is a device file, where the first operation instruction includes a first process identification PID, and the first PID represents that the first operation instruction is delivered by a first process in the first container; determining, according to the first PID, first namespace corresponding to the first container; and deleting all processes in the first container according to the first namespace.
