Abstract
The utility model discloses a red ink test tool of a drawing force test. The red ink test tool comprises a screw used for fixedly connecting with one end surface of a test chip. The other end surface of the test chip is tightly attached onto one end surface of a test PCB. The red ink test tool also comprises a bolt used for matching with the screw. The bolt is further connected with a drawing force test machine. Furthermore, the screw is fixedly connected with the test chip through a viscose glue layer, and the bolt is perpendicular to one end surface of the test chip. The red ink test tool is advantaged by simple structure, convenient operation, and the like. The red ink test tool is suitable for being used during the separation of an IC and the PCB in the process of a red ink test, and is capable of supporting a sample and employing a vertically upward external force to separate the IC and the PCB. Compared with a conventional method of using a tool to realize forced warping, the method of the utility model can substantially reduce pollution caused after the insertion of the tool and enable the fracture layer to be more consistent thanks to the vertically upward drawing, thereby being beneficial for obtaining accurate test effects.
Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of red ink measurement jig of pull-out test.
Background technology
At present, in the red ink test process, usually need to utilize the instruments such as Special-purpose forceps that chip (IC) is separated with pcb board, but in detachment process, tend to cause the instrument perk because the application of force is improper, and then make that the tin ball is destroyed on every side, thereby cause the problems such as test result distortion.And, current along with BGA tin ball sphere diameter processing procedure dwindles gradually, utilize the instrument perk meeting such as Special-purpose forceps to affect to some extent because of the sphere diameter size, cause instrument can't infiltrate chip and pcb board joint inside is operated, quite inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of red ink measurement jig of pull-out test, the advantages such as it has simple in structure, easy to operate, can make test chip accurately separate with pcb board, be beneficial to acquisition and test accurately effect, thereby overcome deficiency of the prior art.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of red ink measurement jig of pull-out test comprises:
In order to the screw be fixedly connected with test chip one end face, described test chip other end fits tightly with test pcb board one end face,
And, in order to the bolt coordinated with described screw, described bolt also is connected with the pull-out test machine.
Further, described screw is fixedly connected with test chip through adhesive-layer.
Further, described bolt is perpendicular to described test chip one end face.
With respect to prior art, the beneficial effects of the utility model are:
1, the utility model by screw and adhesive-layer (as, black glue) with test chip, be connected, and cooperation test pcb board, can select different screws according to the size of sample, realize the adjustment of tool specification, convenience and the high stability of sample variation in the time of can increasing so actual the carrying out of test.
2, can overcome in prior art by the utility model the inconvenience utilization that utilizes the instrument perk fully, make instrument be easy to the penetration test sample interior and carry out.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one preferred embodiment.
Embodiment
Below in conjunction with a preferred embodiment and respective drawings, the technical solution of the utility model is further described.
Consult Fig. 1, the red ink measurement jig of this pull-out test comprises:
In order to the screw 4 be fixedly connected with test chip one end face, described test chip 2 other ends fit tightly with test pcb board 1 one end faces,
And, in order to the bolt 5 coordinated with described screw, described bolt also is connected with pull-out test machine (not shown).
Further, described screw is fixedly connected with test chip through adhesive-layer (the particularly black glue-line 3 after high-temperature baking), and described bolt is perpendicular to described test chip one end face.
The application process of the red ink measurement jig of this pull-out test can comprise:
1, establishing criteria red ink flow process, after completing successively and remove Flux, infiltration red ink, toasting, more sequentially complete according to following order;
2. in the IC back side, utilize black glue to engage and toast with screw;
3. the sample that will be combined to form by IC and pcb board is fixed in the pull-out test machine, and carries out tensile test;
4. read test data, and analyze the red ink invalid position.
After off-test, observe out via the pull-out test machine and carry out pulling out of red ink, can avoid damaging of tin ball, and can utilize data analysis to go out the actual strength of every tin ball.
The utility model is suitable for red ink test assembly to be measured on PCB (printed circuit board (PCB)) or PCBA (assembling printed circuit board (PCB)) while carrying out IC is separated with PCB, and institute is used, can support sample and use external force (direction as shown by the arrows in Figure 1) vertically upward just IC etc. with PCB, separate, compare in the past the tool using method of warpage by force, can significantly reduce the pollution caused because of after the instrument insertion, also, because pull up vertically upward, make more consistance of fracture aspect.
It is pointed out that above embodiment is only for illustrating content of the present utility model, in addition, the utility model also has other embodiments.But all employings are equal to replaces or technical scheme that the equivalent deformation mode forms all drops in protection domain of the present utility model.
Claims (3)
1. the red ink measurement jig of a pull-out test, is characterized in that, comprising:
In order to the screw be fixedly connected with test chip one end face, described test chip other end fits tightly with test pcb board one end face,
