Description
Technical field
The utility model is related to field of semiconductor package more particularly to a kind of ultrasonic bonding equipment aluminum steel conduits.
Background technology
Conductor encapsulation needed for main material include wafer, frame, tin or glue, wire rod (aluminum steel, gold thread, silver wire, copper wire etc.),
Plastic packaging material is aluminum steel in the main material of the wire bonding process of power device semiconductor packages, and welding aluminum steel is used for connecting chip and frame
And play conducting, thus it is very high for the quality requirements of aluminum steel, the problem of being not allow for any bending or damage, in order to true
It protects aluminum steel to convey smooth and be not damaged it is necessary to use conduit to assist in transmission process, the quality height of conduit will be direct
Influence the quality of wire rod, the final quality height for determining finished product and yield rate.
At home and abroad some are large-scale and famous power device semiconductor packages producer is carrying out module encapsulation, as IGBT,
IPM products encapsulate, natural for its main material since IGBT and IPM products are very high for the quality standard requirement of bonding wire
The quality requirements of bonding wire are stringent, are not allow for any quality abnormal, include the quality of solder joint and aluminum steel, so its wire bonding process meeting
Relatively advanced and stable ultrasonic bonding equipment is equipped to meet the quality requirements of bonding wire craft, but Supersonic wave soldering at this stage
The aluminum steel conduit that line machine is equipped with is still using the material as being with conduit used in other bonding equipment manufacturing firms
Conduit and its mode of movement are also the same, and from the point of view of the data being collected into now, this conduit and mode of movement are to aluminum steel
Certain damage is caused, while influencing the quality of solder joint, eventually leads to the overall quality of product.
The raw material of production conduit are common wear-resistant plastics at this stage, therefore when aluminum steel is conveyed in conduit high speed
When, aluminum steel is damaged aluminum steel due to the effect of frictional force with conducting wire inside pipe wall and influences the conveying quality of aluminum steel, is further influenced
To the quality of welding, include the index of solder joint, bonding wire and other main welding qualities.
Therefore, the prior art is defective, needs to improve.
Utility model content
Technical problem to be solved in the utility model is：A kind of aluminum steel is provided and conduit main body inner wall frictional force is small,
Also, aluminum steel does not allow easy damaged, the good ultrasonic bonding equipment aluminum steel conduit of welding quality in transmission.
The technical solution of the utility model is as follows：A kind of ultrasonic bonding equipment aluminum steel conduit, including conduit main body, institute
The inner wall surface for stating conduit main body is additionally provided with the first lubricating layer, also, the introducing port end of the conduit main body
It is set as a bellmouth entrance；The bellmouth entrance medial surface is provided with the second lubricating layer, first lubriation material
Layer is formed with the second lubricating layer one plated film.
Applied to above-mentioned technical proposal, in the ultrasonic bonding equipment aluminum steel conduit, the conduit main body is led
Outlet end is set as an inclination export mouth.
Applied to each above-mentioned technical proposal, in the ultrasonic bonding equipment aluminum steel conduit, the inclination export mouth
Angle of inclination be 41 degree.
Using the above scheme, the utility model by the introducing port end set of the conduit main body be one it is tubaeform enter
Mouthful, it is additionally provided with the first lubricating layer in the inner wall surface of conduit main body, is provided in the bellmouth entrance medial surface
Second lubricating layer, first lubricating layer are formed with the second lubricating layer one plated film；In this way, aluminum steel with
Conduit main body inner wall frictional force is small, also, aluminum steel does not allow easy damaged, welding quality good in transmission.
Description of the drawings
Fig. 1 is the cross section structure schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of ultrasonic bonding equipment aluminum steel conduit is present embodiments provided, as shown in Figure 1, ultrasonic bonding equipment aluminum steel is led
Spool includes conduit main body 10, and conduit main body 10 is a hollow tube, and aluminum steel draws from the introducing port end 101 of conduit main body 10
Enter, the hollow cavity of conduit main body 10 is passed through, and after the extraction of export mouth end 102, for welding.
Wherein, the inner wall surface of 10 hollow tube of conduit main body is additionally provided with the first lubricating layer 104, also,
The introducing port end 101 of the conduit main body 10 is set as a bellmouth entrance；Introducing port end set be it is tubaeform enter
Mouthful, bellmouth entrance is buffer unit, since the effect aluminum steel of buffering can more swimmingly enter conduit, is also ensured that
Aluminum steel it is intact.
The bellmouth entrance medial surface is provided with the second lubricating layer 103, first lubricating layer 104 and institute
It states the integrated plated film of the second lubricating layer 103 to form, alternatively, the first lubricating layer 104 and the second lubricating layer 103 can be with
Be made of identical material using with the conduit main body 10, wherein use be high-lubrication wear-resisting engineering plastics,
First lubricating layer 104 and the second lubricating layer 103 integrally mould molding with the conduit main body 10, simple for process；
High lubriation material is selected, the frictional force of aluminum steel and conducting wire inside pipe wall is significantly reduced, avoids aluminum steel in high speed transmission process
It is damaged, it is ensured that intact bonding wire reaches welding work step and final welding quality, while improving its service life.
Alternatively, as shown in Figure 1, the export mouth end 102 of the conduit main body 10 is set as an inclination export mouth, also,
The angle of inclination 105 for tilting export mouth is 41 degree, in this way, by setting export mouth end 102 to an inclination export mouth.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
Within the scope of shield.
