Embodiment

[0031] A method for improving drilling efficiency, comprising the following:

[0032] 1. The definition of pumping T: on the basis of the existing drilling, select a part to be drilled according to the higher order;

[0033] 2. The principle and steps of automatic selection and extraction of T drilling

[0034] Principle: Select within the range of the inner / outer copper skin, at least 8mil away from the edge of the copper skin, and the distance between the drill holes is greater than 8mil, and the increase will not affect the lack of annular rings and hole spacing;

[0035] step:

[0036] A: Drill holes according to the normal compensation and then select pumping T drilling;

[0037] B: The copper skin composed of lines needs to be converted into copper blocks;

[0038] C: Select the drill holes included in the 8mil copper skin of each layer;

[0039] D: Select the selected holes and delete the drilled holes that are less than 8mil away from other holes;

[0040] The abo...

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...
