Burr removing method of right-angle connection position in PCB edge groove

Abstract

The invention discloses a burr removing method of a right-angle connection position in a PCB edge groove. The method comprises the following steps of S1, drilling a PCB laminated board to be processedthrough a drilling machine, wherein each processed hole accords with each technological requirement; S2, carrying out gong groove processing on the PCB laminated board obtained in the step S1 by adopting a gong board machine, and carrying out gong groove processing on an edge groove; S3, carrying out shape gong cutter rough gong cutting forming on the PCB laminated board obtained in the step S2 by adopting the gong board machine; and S4, carrying out shape gong cutter fine gong finishing on the preliminarily formed PCB laminated board obtained in the step S3 by adopting the gong board machine. In the step S1, deburring holes are drilled in positions, where burrs are likely to be generated, of right-angle connection in the edge groove to be processed of the PCB laminated board, the deburring holes are located in the edge groove to be processed, a diameter of the deburring holes is less than a width of the edge groove to be processed, and an intersection depth of the deburring holes anda right angle in the edge groove to be processed is not greater than 0.1 mm. The burr removing method of the invention can be used for deburring the right angles in the edge grooves with various sizes and widths, cost is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of PCB board manufacturing, and more specifically, relates to a method for removing burrs applied to the right-angled intersection position of the drill and gong of the PCB board. Background technique [0002] In the process of PCB manufacturing, because the main shaft of the gong machine rotates clockwise, so in the process of cutting side grooves, such as figure 2 As shown, the retrograde position indicated by the right-angle arrow on the top will produce right-angle burrs. The usual method is: first make the edge groove of the gong knife, then cut the shape, and finally use a smaller type of gong knife to remove the burr at the right angle in the side groove. For side grooves with a width of more than 0.8cm, the above-mentioned small-sized gong cutter is generally used to remove the hair at right angles in the side groove, because the stroke and replacement of the gong cutter will have a certain impact on the produ...
