Between combination, and high temperature can accelerate atom combine.Plastic deformation can because vibration friction, dynamics, the change of the factor such as time and send out
Raw fracture, rosin joint, or lead to the problems such as components and parts functional defect or later stage inefficacy letter after reliability test.Some fixtures because
Ji Dao pressing is bad to lead to solder ball shape excessive, and beyond pad, potential bonding failure probability increases, and affects bonding quality, therefore
Barrier rate is high.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of bonding with arc-shaped step to control
Tool, the bonding tool that this has arc-shaped step can improve stitching state thus can be prevented effectively from short circuit in wire bonding process
Phenomenon occurs, and improves product yield.
The technical solution of the utility model is as follows：
A kind of bonding tool with arc-shaped step, for anchor leg framework, matches including pressing plate and with described pressing plate
Co-clip presses the substrate of described lead frame, and described substrate includes substrate matrix and the unit bonding being arranged on described substrate matrix
Area, described unit bonding region is to be formed by several bonding units matrix arrangement, and described bonding units include Ji Dao, described Ji Dao
There is upper and lower surface, the lower end of described Ji Dao is at least provided with an arc-shaped step, the bottom surface of described arc-shaped step and institute
The lower surface on Shu Ji island is in the same plane, and the height of described arc-shaped step is less than the height of described Ji Dao, and described Ji Dao leads to
The supporting role crossing described arc-shaped step makes the lower surface of Ji Dao press described substrate matrix.
As the improvement further of technique scheme, the lower end of described Ji Dao is sequentially provided with two arc-shaped step, and this two
The height of individual arc-shaped step successively decreases from top to bottom successively.
Wherein, described bonding units are provided with 10, the permutation arrangement of one-tenth 2 rows, often row 5.
Compared with prior art, the beneficial effects of the utility model are：This utility model at least sets in the lower end of Ji Dao
There is an arc-shaped step, the bottom surface of this arc-shaped step is in the same plane with the lower surface of Ji Dao, and the height of arc-shaped step is low
In the height of Ji Dao, by the support of described arc-shaped step, so that base island adhesive substrates matrix Shi Ji island lower surface is easily floating
It is firm that dynamic position is pressed, and during the pressing of Ling Ji island in same level, thus improving soldering reliability, improves yield rate.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed
Describe in detail bright, specific embodiment of the present utility model is shown in detail in by following examples and its accompanying drawing.
Brief description

Schematic description and description of the present utility model is used for explaining this utility model, does not constitute to of the present utility model improper
Limit.In the accompanying drawings：
Fig. 1 is the structural representation of the bonding tool described in this utility model embodiment with arc-shaped step；
Fig. 2 is the enlarged drawing at A in Fig. 1.
Description of symbols in accompanying drawing：
1-- substrate 11-- substrate matrix
2-- unit bonding region 21-- bonding units
211-- base island 3-- arc-shaped step.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, to describe this utility model in detail：
This utility model provides a kind of bonding tool with arc-shaped step, for anchor leg framework, as shown in figure 1,
The bonding tool that this has arc-shaped step includes pressing plate（Not shown）And the described lead frame of cramping that matches with described pressing plate
Substrate 1, described substrate 1 includes substrate matrix 11 and the unit bonding region 2 being arranged on described substrate matrix 11, described unit key
Closing area 2 is to be formed by several bonding units 21 matrix arrangement, and in the present embodiment, described bonding units 21 are provided with 10, becomes 2
The permutation arrangement of row, often row 5.
As shown in Fig. 2 described bonding units 21 include base island 211, described base island 211 has upper and lower surface, is
Avoid the height error that during described base island 211 pressing, lower surface produces to cause floating, the lower end on described base island 211 at least provided with
One arc-shaped step 3, the bottom surface of described arc-shaped step 3 is in the same plane with the lower surface on described base island 211, described arc
