description	The invention relates to the technical field of drill pins, and particularly to a PCB drill pin and a drill pin process effect detection method. The PCB drill pin comprises a handle part and a tungsten carbide blade connected to the handle part, wherein the tungsten carbide blade contains cobalt metal; the tungsten carbide blade has a diameter of 0.2 mm; the outer layer of the tungsten carbide blade is provided with a plurality of film layers; and the film layer is made of a mixture of titanium nitride, titanium carbide, aluminum oxide and titanium carbonitride, or, a mixture of titanium carbide and titanium aluminum nitride, or titanium aluminum carbonitride. The film layers made of one or multiple combined materials selected from titanium nitride, titanium carbide, aluminum oxide, titanium carbonitride, titanium aluminum nitride, and titanium aluminum carbonitride on the micro drill pin with a diameter of 0.2 mm, the rigidity of the drill pin is enhanced, the service life is prolonged to twice that of the t
