Abstract
The utility model relates to a replacement carrying platform for a PCB with a BGA. The replacement carrying platform comprises a platform body for fixing the PCB and a fixing block for fixing the BGA which is mounted on the PCB. The platform body comprises a frame and a supporting part which is arranged inside the frame to support the PCB. An upper plane of the supporting part is lower than an upper plane of the frame. The supporting part is provided with two first fixing holes for fixing the fixing block. The fixing block is a square-loop-shaped sheet body. The fixing block is provided with second fixing holes at such positions to correspond to the first fixing holes. The second fixing holes are provided at opposite corners of the fixing block. The first fixing holes and the second fixing holes are connected via fasteners. The BGA is fixed between the supporting part and the fixing block. In the utility model, the pressure of four edges of the BGA which is already heated is made to be uniform by the lower supporting part and the upper fixing block, providing convenience for detaching and replacing the BGA from the PCB, effectively enhancing the replacement success rate, improving the product yield rate and saving materials.
Description
Technical field
the utility model relates to a kind of PCB replacing microscope carrier that is used to be equipped with BGA.
Background technology
BGA is the PCB (Ball Grid Array) of ball grid array structure, in the course of processing, need heat it.Method to its heating in the prior art is following: adopt tool as shown in Figure 4, this tool has a frame 4, and the inside of frame 4 is furnished with many brace rods 5 anyhow; Establish on the brace rod 5 to the fixed strip 6 that PCB is fixing is arranged; When needing heating, BGA is fixed on the PCB, PCB is placed on the brace rod 5; And through fixed strip 6 each limit of PCB is fixed, tool is put into the heating board BGA is heated; After heating finishes, BGA is pulled down from PCB, whether it is checked qualified, and another BGA is installed.But during owing to heating, PCB and BGA all are heated, and PCB tends to because of being heated deformation take place, and when BGA is changed, can cause the bad of BGA, causes and scraps, thereby influence the yield of product, have also wasted material, have increased cost.
Summary of the invention
The purpose of
the utility model provides a kind of PCB replacing microscope carrier that is used to be equipped with BGA.
For achieving the above object, the technical scheme that the utility model adopts is:
a kind of PCB replacing microscope carrier that is used to be equipped with BGA; It comprises one fixedly PCB body, can be fixedly mounted on the fixed block that PCB goes up BGA; Described body comprises frame, is arranged on the support portion that described PCB can be supported in described frame inside; The last plane of described support portion is lower than the last plane of described frame, offers 2 first fixing holes that are used for fixing described fixed block on the described support portion; Described fixed block is a side ring load body; The position of corresponding described first fixing hole offers 2 second fixing holes on the described fixed block; 2 described second fixing holes are opened on 2 diagonal angles of described fixed part; Described first fixing hole, second fixing hole are connected through securing member, and described BGA is fixed between described support portion and the fixed block.
preferably, the position that described frame inside is not provided with described support portion is dug and is worn.
preferably, described support portion is provided with the reference column that is used to locate PCB.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
The fixed block on the support portion of the replacing microscope carrier of
the utility model through the bottom, top makes the BGA four limit pressure after the heating even; Making things convenient for BGA to pull down from PCB changes; The success rate of the replacing that effectively improves has improved the yield of product, and has saved material.
Description of drawings
Accompanying drawing 1 is a main body structure sketch map in the utility model;
Accompanying drawing 2 is the structural representation of fixed block in the utility model;
Accompanying drawing 3 is fixed on the sketch map on the body for fixed block in the utility model;
accompanying drawing 4 is the fixture sketch map of prior art.
wherein: 1, body; 10, frame; 11, support portion; 110, reference column; 12, first fixing hole; 2, fixed block; 20, second fixing hole; Securing member.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
A kind of PCB that is used to be equipped with BGA as shown in Figure 3 changes microscope carrier, it comprise one fixedly PCB body 1, can be fixedly mounted on the fixed block 2 that PCB goes up BGA, specifically:
are as shown in Figure 1: body 1 comprises frame 10, is arranged on the support portion 11 that PCB can be supported in frame 10 inside; And the last plane of support portion 11 is lower than the last plane of frame 10; That is to say that after PCB was placed on the support portion 11, the upper surface of PCB can not be higher than the upper surface of frame 10 or flush with it; And frame 10 inside are not provided with the position of support portion 11 and dig and wear, and avoid the part of PCB bottom impaired because of pushing.The body 1 of present embodiment is applicable to that PCB has the model in 2 holes around BGA, promptly offer 2 first fixing holes 12 that are used for fixing this fixed block 2 on the support portion 11;
are as shown in Figure 2: fixed block 2 is side's ring-type lamellar body, offers 20,2 second fixing holes 20 of 2 second fixing holes in the position of corresponding first fixing hole 12 on the fixed block 2 and is opened on the diagonal angle of fixed part 2.
in addition, support portion 11 is provided with the reference column 110 that is used to locate PCB.
in use; PCB is placed on the support portion 11, and reference column 110 passes the location hole on the PCB, and PCB is fixed on the support portion 1 stably; BGA is placed on the PCB; And 2 first fixing holes 12 on the corresponding support portion 11, with second fixing hole, 20 corresponding first fixing holes 12 of fixed block 2, first fixing hole 12, second fixing hole 20 are connected through securing member (like screw); Four limits of BGA then are fixed between support portion 11 and the fixed block 2; After BGA was heated, the support portion 11 through the bottom, the fixed block 2 on top made the pressure on BGA four limits after the heating even, are replaced with power because of PCB receives high temperature deformation to influence it when preventing to change BGA.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection range of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the utility model.
