Abstract
The utility model discloses a bonding wire wire drawing mould, this mould are equipped with a cross -section along the axial and include first inlet region, first compression zone, sizing district, second compression zone, the second entrance district in proper order for circular shape through -hole, through -hole from the top down. The utility model discloses a bonding wire wire drawing mould compares with prior art, the life -time dilatation one time of mould, and the manufacturing cost of bonding wire preparation in -process is effectively reduced, and the surface quality of bonding wire product is not influenced.
Description
Technical field
The utility model relates to mould, is specifically related to a kind of bonding wire wire-drawing die.
Background technology
At present, along with the development of Electronic Packaging industry, the demand of bonding wire used for electronic packaging is also increasing. The drawing of bonding wire is the main technique that bonding wire is manufactured, and bonding wire mould is one of auxiliary material the most key in bonding wire manufacture process. Because bonding wire die cost is higher, the reasonable use of bonding wire mould, the cost that how to reduce bonding wire mould also seem particularly important.
As shown in Figure 2, existing bonding wire mould structure one end is bonding wire entrance, bonding wire is penetrated from die entrance wearing in a process, behind sizing area 6, extracts from the outlet area 7 of another side mould, to reach the bonding wire effect of drawing-down gradually. It is to be that porch is provided with inlet region 8 and compressional zone 9 that bonding wire die entrance is different from bonding wire mould outlet, and because inlet region 8 is regions of frictional force maximum to compressional zone 9, after using a period of time, the edge of bonding wire mould compressional zone is easily wearing and tearing just. Even if now do not wear and tear in the sizing area of bonding wire mould, but continue the mould that uses compressional zone to be worn, will affect the surface quality of bonding wire. Therefore, be to ensure the quality of bonding wire, need to eliminate that compressional zone is impaired and wire-drawing die that sizing area and outlet area are intact causes waste.
Utility model content
The problem existing for above-mentioned prior art, the utility model provides a kind of bonding wire wire-drawing die, and it is not affecting under the prerequisite of bonding wire quality, and double service life, can effectively reduce the production cost in bonding wire preparation process.
Above-mentioned purpose realizes by following proposal:
A kind of bonding wire wire-drawing die, is characterized in that, it is circular through hole that this mould is provided with a cross section vertically, and described through hole comprises the first inlet region, the first compressional zone, sizing area, the second compressional zone, the second inlet region from top to bottom successively.
According to above-mentioned bonding wire wire-drawing die, it is characterized in that, the inlet angle of described the first inlet region equals the inlet angle of described the second inlet region, and the compression angle of described the first compressional zone equals the compression angle of described the second compressional zone.
The beneficial effects of the utility model:
Bonding wire wire-drawing die of the present utility model compared with prior art, one times of the life of mould, the production cost in bonding wire preparation process is effectively reduced, and the surface quality of bonding wire product is unaffected.
Brief description of the drawings
Fig. 1 is the profile of bonding wire wire-drawing die of the present utility model.
Fig. 2 is the profile of bonding wire wire-drawing die of the prior art.
Detailed description of the invention
As shown in Figure 1, bonding wire wire drawing grinding tool of the present utility model is provided with a through hole vertically, and the cross section of through hole is circular, and through hole comprises the first inlet region 1, the first compressional zone 2, sizing area 3, the second compressional zone 4, the second inlet region 5 from top to bottom successively. Preferably, the inlet angle α of the first inlet region 1 equals the inlet angle β of described the second inlet region 5, and the compression angle γ of described the first compressional zone 2 equals the compression angle θ of described the second compressional zone 4. Like this, the outlet of wire-drawing die and entrance have identical structure. In the time wearing thread, first use the first inlet region 1 to penetrate face as bonding wire, through the first compressional zone 2, then through sizing area 3, then from the second compressional zone 4, the second inlet region 5 out. Through use after a while, the first compressional zone 2 edge abrasions, for avoiding bonding wire surface quality to be affected, use the penetrate face of the second inlet region 5 as bonding wire, bonding wire is successively through the second inlet region 5, the second compressional zone 4, sizing area 3, the first compressional zone 2 and the first inlet region 1.
The entrance and exit of bonding wire wire-drawing die of the present utility model has identical structure, in the time that wearing and tearing occur the entrance of bonding wire wire-drawing die, the outlet of wire-drawing die can be used as entrance.
