Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] Such as figure 1 Shown is a method for manufacturing a short slot hole in an aluminum substrate provided by the present invention, which includes the following method steps:

[0029] S1. To make drill tape, according to the multiple relationship between groove length and groove width in the range: 1.0 times groove width < groove length < 2.0 times groove width, several kinds of groove length and groove width multiple relationships are designed to correspond to different groove holes.

[0030] First of all, the drill tape is made, and according to the multiple relationship between...

Abstract

The invention discloses a method of preparing aluminum base board short groove holes. The method of preparing the aluminum base board short groove holes comprises the following steps: due to the fact that multiple relationship range between the length of the groove and the width of the groove is that 1.0 time the width of the groove is smaller than the length of the groove which is smaller than 2.0 times the width of the groove, a plurality of multiple relationships between the length of the groove and the width of the groove, corresponding to different groove holes, are designed. Machined groove holes, after cutting an aluminium sheet, served as a drilling belt to drill, and the offset of the drilling result is measured through quadratic element. According to an acquired measure result, the designed groove hole is compensated in reverse angle to make drilling belt data. Drilling is performed according to the drilling belt data. Targeted on procession drilling belt of the short groove hole, according to the proportional relationship between the length of the groove hole and the width of the groove hole, certain angle is compensated, and therefore the drilled groove hole is prevented from skewing and deforming. And guiding hole drilling hole is not needed, production efficiency and production quality is greatly improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing printed circuit boards, in particular to a method for manufacturing short slot holes on an aluminum substrate. Background technique [0002] With the development of modern electronic products towards miniaturization, high integration and high performance, the diameter of the drilled holes is getting smaller and smaller, the drilling precision is getting higher and higher, there are more and more slots, and the quality requirements are getting higher and higher. High, especially the production of slots, its quality directly affects the installation and use of customer products, and the slots are prone to offset and deformation problems during production, which not only seriously affects production efficiency and quality, but also increases production costs , especially for making metal substrates. This also shows that the current PCB manufacturing industry is facing the confusion of short sl...
