The invention discloses a multi-bridging position and small-spacing edge-wrapped printed circuit board and a manufacture method thereof. The multi-bridging position and small-spacing edge-wrapped printed circuit board is mainly composed of a circuit board; a side surface of the circuit board is provided with a metal wrapping edge; and the metal wrapping edge is '']''-shaped, or the upper end surface of the metal wrapping edge is connected with a top surface pattern, and the lower end surface of the metal wrapping edge is connected with a bottom surface pattern. The invention also discloses a manufacture method of the multi-bridging position and small-spacing edge-wrapped printed circuit board. The method includes the following steps that: first step, wrapping edge design: a '']''-shaped metal wrapping edge is designed at one side surface of a circuit board; second step: mirroring half hole drilling design: drilling tool diameter selection is carried out, drilling location selection is carried out, and finally drilling compensation design is carried out; and third step, mirroring half hole drilling manufacture which includes drilling file manufacture, drilling positioning and board loading for half hole drilling. The manufacture method of the invention is applicable to a multi-bridging position and small-spacing edge-wrapped printed circuit board. With the manufacture method adopted, when hole drilling is carried out, copper sheets will not be raised; and when board milling is carried out, copper sheets at small bridging positions will not cock and fall off.
