Method for improving drilling efficiency

Abstract

The invention discloses a method for improving drilling efficiency. The method comprises the following contents: 1) extraction T definition: based on traditional drilling, one part is selected for manufacturing according to next-order drilling; and 2) principle and steps of automatically selecting extraction T drilled holes: principle: in the inner layer / outer layer copper sheet range, the distances from the edges of copper sheets are at least 8 mil; the gaps between the drilled holes are larger than 8 mil; and the hole ring shortage and the hole distance shortage cannot be influenced after enlargement of the gaps; and steps: (A) the drilled holes are normally compensated; and the extraction T drill holes are selected; (B) the copper sheets formed by circuits need to be converted to copper blocks; (C) the drilled holes within 8 mil of each layer of circuit copper sheets are selected; and (D) the drilled holes with the distances of lower than 8 mil from other holes are selected for deletion. The method has no need of manual selection of enlarged VIA holes, cannot influence the data after enlargement, reduces the use rate of a drilling nozzle, and replaces a small drilling nozzle by using a larger drilling nozzle.

Description

technical field [0001] The invention relates to a method for improving drilling efficiency. Background technique [0002] The customer provides the original data for the engineering production, and the VIA hole compensation is generally 0-0.05mm. If the VIA aperture compensation is too large, it will affect the optimization time of the engineering data, and if the spacing is not enough, the drilling aperture will be reduced, and the drilling that can be enlarged is not selected. In this way, It is manifested as: [0003] 1. The existing drilling only distinguishes BGA; [0004] 2. The same type of drilling is basically uniformly enlarged or reduced; [0005] 3. After the increase, the spacing is insufficient, and it takes a long time to manually optimize the line or move the hole and shrink the cavity. [0006] Disadvantages of existing technology: [0007] Drilling is compensated by 0-0.05mm according to the routine, and the hole diameters with insufficient spacing afte...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing drilling only distinguishes BGA;

[0004] 2. The same type of drilling is basically uniformly enlarged or reduced;

[0005] 3. Insufficient spacing after enlarging, manually optimizing the line or moving the hole, shrinking the cavity, takes a long time

[0007] Drilling holes are usually compensated by 0-0.05mm. After compensation, the hole diameters with insufficient spacing are not compensated or the compensation is too small and smaller drills are used, resulting in excessive use of small drills and higher costs in all aspects.
