Abstract

The invention discloses a special-shaped hole deburring method which comprises the following steps of (1) adding deburring holes at the junctions of special-shaped holes; and (2) cutting off outwards by 4mil at the junctions of the deburring holes and the special-shaped holes so as to complete deburring of the special-shaped holes. According to the special-shaped hole deburring method, by improving burrs in rear holes, the defect rate is reduced to 30 percent, quality of products is improved, and raw materials are saved.

Description

The profiled holes burr removing method
Technical field
The present invention relates to a kind of burr removing method, particularly relate to a kind of profiled holes burr removing method.
Background technology
During existing pcb board was made, during profiled holes boring, the hole inner burr was bad, the hardy hole of 1.1mm slotted eye+2.45mm circular hole particularly, and hole inner burr 100% is bad, greatly reduces like this quality of product, has wasted raw material, has increased cost.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to, provide a kind of profiled holes burr removing method, to reduce hole inner burr fraction defective.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the profiled holes burr removing method, it is characterized in that, and may further comprise the steps:
(1) in the profiled holes intersection, adds the unhairing acanthopore;
(2) in unhairing acanthopore and profiled holes intersection, outwards cut away 4mil, the profiled holes deburring is finished.
Aforesaid profiled holes burr removing method is characterized in that, described profiled holes two hole pitch of holes 〉=5mil, wherein small diameter 〉=0.8mm.
Aforesaid profiled holes burr removing method is characterized in that, described deburring bore dia is 0.4mm.
Aforesaid profiled holes burr removing method is characterized in that, described profiled holes is the pass of slotted eye+circular hole, circular hole+circular hole.
The invention has the beneficial effects as follows: be down to 30% by improving metapore inner burr fraction defective, improved the quality of product, saved raw material.
Description of drawings
Fig. 1 is the schematic diagram of profiled holes unhairing acanthopore among the present invention.
Embodiment
Be further to disclose technical scheme of the present invention, describe embodiments of the present invention in detail below in conjunction with accompanying drawing: as shown in Figure 1, take the profiled holes of slotted eye+circular hole as example, the profiled holes burr removing method may further comprise the steps:
(1) in the profiled holes intersection, add the unhairing acanthopore, described profiled holes two hole pitch of holes 〉=5mil, small diameter 〉=0.8mm wherein, the deburring bore dia is 0.4mm.
(2) in unhairing acanthopore and profiled holes intersection, outwards cut away 4mil, the profiled holes deburring is finished.
Wherein, described profiled holes is the pass of slotted eye+circular hole, circular hole+circular hole.
The present invention is down to 30% by improving metapore inner burr fraction defective, has improved the quality of product, has saved raw material.
More than by description of listed embodiment, the basic ideas and basic principles of the present invention have been set forth.But the present invention never is limited to above-mentioned listed execution mode, and every equivalent variations, improvement and deliberately of inferior quality behavior of change of doing based on technical scheme of the present invention all should belong to protection scope of the present invention.

Claims (4)

1. the profiled holes burr removing method is characterized in that, may further comprise the steps:
