Abstract
The utility model discloses a ball mounting clamp which comprises a lower die and an upper die matching with the lower die; the lower die comprises a base on which a convex platform is arranged and the convex platform is provided with a clamping device which can fix a ball grid array(BGA); the upper die is fixedly provided with a BGA steel mesh; a BGA fixing device comprises at least two sliding chutes arranged on the convex platform and locating columns arranged on the sliding chutes; and the upper die comprises a lower bottom plate, an upper clamping ring and the BGA steel mesh fixed between the lower bottom plate and the upper clamping ring. The ball mounting clamp adopts the lower die to fix the BGA, the upper die is provided with the BGA steel mesh and a tin ball is arranged at the corresponding position of the BGA steel mesh. Through the matching of the lower die and the upper die, the tin ball is accurately arranged on the BGA, thus improving working efficiency.
Description
[technical field]
The utility model relates to clamp for machining, relates in particular to one kind and plants the ball chuck tool.
[background technology]
In the process that the BGA after being assemblied in circuit board is detected, may detect the BGA that some exist short circuit, empty weldering.At this moment, BGA need be taken off from circuit board and plant ball again, be convenient to utilize again BGA.Plant the ball process for welding material is arranged on the corresponding position of BGA by the BGA steel mesh.
Therefore, how designing a kind of anchor clamps makes welding material to be arranged to exactly to seem particularly important on the BGA.
[utility model content]
In view of this, be necessary to provide one kind to plant the ball chuck tool, can exactly welding material be arranged on the BGA, increase work efficiency.
For achieving the above object, following technical scheme is proposed:
Plant the ball chuck tool for one kind, comprise counterdie and the patrix suitable with it:
Described counterdie comprises base, and described base is provided with boss, and described boss is provided with the fixedly clamping device of BGA;
Described patrix is set with the BGA steel mesh.
In preferred embodiment, described BGA fixture is included at least two chutes that are provided with on the described boss, and is located at the reference column on the described chute.
In preferred embodiment, described chute is two or four, and described chute is symmetrical in the center of described boss.
In preferred embodiment, described patrix comprises lower shoe and the last clamp ring that cooperatively interacts, and the BGA steel mesh of fixing between described lower shoe and the last clamp ring.
In preferred embodiment, the described clamp ring of going up is provided with breach.
As can be seen from the above technical solutions, planting the ball chuck tool adopts counterdie that BGA is fixed, and patrix is provided with the BGA steel mesh, welding material is placed on the BGA steel mesh, counterdie is aimed at patrix, can exactly the tin ball be arranged on the BGA so that welding material attaches to the correspondence position of BGA pad, improve operating efficiency.
[description of drawings]
Fig. 1 is the structure chart of planting ball chuck tool counterdie;
Fig. 2 is the structure chart of planting ball chuck tool patrix.
[embodiment]
Be described in detail below in conjunction with specific embodiment and Figure of description.
With reference to figure 1 and Fig. 2, to plant the ball chuck tool and comprise counterdie 100 and the patrix 200 suitable with it, counterdie 100 will definitely make welding material can accurately fall into the position of BGA pad with 200 pairs of patrixes.
Counterdie 100 comprises base 102, and base 102 is provided with boss 104, is provided with chute 106 between boss 104.Counterdie 100 also comprises the fixedly clamping device 108 of BGA, and this clamping device 108 is located in the chute 106 the fixedly BGA of different size.
Be set with the BGA steel mesh on the patrix 200, place welding material on the BGA steel mesh, with counterdie 100 with after patrix 200 is aimed at, through hole on the steel mesh and the contraposition of BGA pad, thus make welding material to be arranged to exactly on the relevant position of BGA.
Plant in the ball technology to adopt at BGA and plant the ball chuck tool, can exactly welding material be arranged on the BGA, improved operating efficiency.
Embodiment one
In the present embodiment, counterdie 100 is provided with four chutes 106 at the center that is symmetrical in boss 104, and is located at the clamping device 108 on the chute 106.As shown in Figure 1,106 one-tenth " ten " fonts of four chutes are arranged on the boss 104, by the fixing BGA of four clamping devices 108, and, therefore can clamp the BGA of different sizes by mobile clamping device 108 because clamping device 108 is movably connected in the chute 106.
Embodiment two
In the present embodiment, counterdie 100 is provided with two chutes 106 at the center that is symmetrical in boss 104, and is located at the clamping device 108 on the chute 106.106 one-tenth " one " fonts of two chutes of present embodiment are arranged on the boss 104, by the fixing BGA of two clamping devices 108, and, therefore can clamp the BGA of different sizes by mobile clamping device 108 because clamping device 108 is movably connected on the chute 106.
Need to prove that the BGA fixture can comprise a plurality of chutes 106 that are arranged on the boss 104, and be located at the reference column 108 on the chute 106, be not limited to the execution mode among above-mentioned two kinds of embodiment.
Embodiment three
In the present embodiment, patrix 200 comprises lower shoe 202 and the last clamp ring 204 that cooperatively interacts, and the base 102 of the shape of lower shoe 202 and counterdie 100 adapts, and last clamp ring 204 is a rectangular shaped rim.Be fixed with BGA steel mesh 203 between lower shoe 202 and the last clamp ring 204, can place welding material at the BGA steel mesh from the window that last clamp ring 204 forms.Steel mesh 203 is provided with a plurality of through holes 205, and welding material attaches on the pad of BGA by through hole 205, and re-using heat gun can become soldered ball with the welding material on the pad.BGA steel mesh 203 can be fixed by four pins 206.
Embodiment four
On the basis of embodiment three, last clamp ring 204 is provided with breach 208, is convenient to welding material unnecessary on the BGA steel mesh 203 is removed from breach 208.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
