Embodiment Construction

[0016] The present invention provides a PCB board manufacturing method and PCB board for improving short slots and slots. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] A preferred embodiment of the method for making PCB boards for improving short slots and slots provided by the present invention includes steps:

[0018] When using a groove cutter to drill grooves, the lower point of the cutter is used as the center of the circle, and the groove angle pre-compensation value is increased clockwise to improve the groove skew of the drilled short groove.

[0019] Such as figure 1 As shown, when the traditional method is used for processing, the lower knife point 100 is the center of the circle, and...

Abstract

The invention discloses a PCB manufacturing method for modifying crooked short grooves and a PCB. The manufacturing method comprises the steps that when a grooving cutter is used for drilling grooves, the point where the cutter firstly cuts is regarded as the circle center, the angle pre-compensation value of the grooves is increased in the clockwise direction, and the crooked short grooves are modified. According to the PCB manufacturing method, when the grooving cutter is used for drilling grooves, the point where the cutter firstly cuts is regarded as the circle center, the angle pre-compensation value of the grooves is increased in the clockwise direction, and the crooked short grooves are modified, so that product quality is guaranteed, and the purpose of improving production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a method for making a PCB board and a PCB board for improving short groove skew. Background technique [0002] In the prior art, the method of processing short grooves on PCB boards is generally to drill pilot holes at both ends of the grooves first, and then use a groove cutter to drill out short grooves. If the short groove is short, the groove will be crooked, which can only be controlled by reducing the number of stacks during production, which cannot completely improve the phenomenon of short groove crookedness and reduce production efficiency. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a PCB board manufacturing method and a PCB board for improving the short groove skew, aiming at solving...
