Description

[0001] The utility model relates to the technical field of circuit board punching, in particular to a multi-layer circuit board multi-hole punching machine. Background Art

[0002] Punching is a common processing technology that achieves specific functions by making holes on the surface of materials. The principle of punching is to use a punch to apply pressure to the material, causing the material to undergo plastic deformation, thereby forming holes for subsequent circuit wiring and component installation.

[0003] The prior art discloses patent application number "CN201922231364.1", a circuit board punching machine, a designed first threaded rod and a sliding rod, which cooperate with the rear fixed plate to clamp circuit board substrates of different lengths.
