Title:
METHOD FOR MOUNTING VIA HOLE ON PCB
Document Type and Number:
WIPO Patent Application WO/2020/042694
Kind Code:
A1
Abstract:
A method for mounting a via hole on a PCB, comprising: providing a mounting hole on a PCB body; inserting a via hole preform into the mounting hole to allow an annular via hole base body in the middle of the via hole preform to be located in the mounting hole, and to allow connection arms provided at two ends in the axial direction of the via hole base body in the via hole perform to correspondingly extend out of the two ends of the mount hole; and correspondingly adjusting the connection arms along a boundary line between the connection arms and the via hole base body to allow the connection arms to swing to corresponding surfaces on the PCB body and to be fixed. The method employs a mode of maintenance of a PCB to additionally provide a via hole to obtain a required PCB, without the need of re-making a board as in the prior art, and the mode of obtaining the required PCB is efficient. Moreover, the method can be completed by means of manual operation, is high in flexibility, and can save production costs without the need of additionally manufacturing or purchasing a special mounting device.
