Description
Technical field
The utility model belongs to test fixture field, especially relates to a kind of integrated circuit board test fixture.
Background technology
Need to carry out manual test to the electrical characteristics of surface-mounted integrated circuit in development & production process, this manual test generally needs to carry out on manual test fixture, manual test clamp base is fixed with test board, test board surface is fixed with testing circuit board, compliant conductive pad is equipped with on testing circuit board surface, surface-mounted integrated circuit to be tested is placed on compliant conductive pad, and with suction nozzle, surface-mounted integrated circuit is pressed on compliant conductive pad, prevent surface-mounted integrated circuit and testing circuit board loose contact.In existing technology, downforce is directly passed to surface-mounted integrated circuit by drive link and suction nozzle by handle, cause the downforce size of each test all not identical, and the test result obtained for same surface-mounted integrated circuit due to the difference of the operator's operating force person that causes different operating is not identical yet.Cause two kinds of test result differences more obvious because the downforce of Auto-Test System in manual test downforce and product line differs greatly.Exist and press down the technical matterss such as dynamics is uncontrollable, consistance is poor.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of integrated circuit board test fixture, is especially applicable to controlling suction nozzle downforce size.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of integrated circuit board test fixture, comprise test board, base, column, handle, drive link, limited block, suction nozzle and spring, described base is provided with the stationary installation for fixing described test board, described column bottom is fixed on base, described column top is provided with projection outstanding forward, described handle one end is provided with connecting portion, described connecting portion and described projection are rotationally connected, described connecting portion is connected with described drive rod rotation, described limited block is fixed on the bottom of projection, described limited block is provided with spacing hole, described spacing hole is radial perpendicular to base, described drive link is through spacing hole, described suction nozzle is connected with described drive link end by spring.
Further, also comprise connector, described drive link end is fixedly connected with described connector one end, the described connector other end is provided with through hole, described suction nozzle top is fixedly connected with guide rod, described guide rod passes spring and stretches out from described through hole, and described lower spring end is connected with suction nozzle top, and spring top is connected with described connector.
Further, described stationary installation comprises fixed orifice and guide groove, and described fixed orifice is arranged on bottom described guide groove, and described test board can slide the relative position regulating test board and suction nozzle in guide groove.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, the size of suction nozzle downforce can be controlled, ensure that manual test downforce is consistent with Automatic test clamp downforce, improve the consistance of manual test result and automatic test result.

Embodiment
As shown in Figure 1, a kind of integrated circuit board test fixture of the utility model, comprise test board 1, base 2, column 3, handle 4, drive link 5, limited block 6, suction nozzle 7 and spring 8, base 2 is provided with the stationary installation for fixing test platform 1, column 3 bottom is fixed on base 2, column 3 top is provided with projection 9 outstanding forward, handle 4 one end is provided with connecting portion 10, connecting portion 10 and projection 9 are rotationally connected, connecting portion 10 and drive link 5 are rotationally connected, limited block 6 is fixed on the bottom of projection 9, limited block 6 is provided with spacing hole, spacing hole is radial perpendicular to base 2, drive link 5 is through spacing hole, suction nozzle 7 is connected with drive link 5 end by spring 8, also comprise connector 11, drive link 5 end is fixedly connected with connector 11 one end, and connector 11 other end is provided with through hole, suction nozzle 7 top is fixedly connected with guide rod 12, guide rod 12 passes spring 8 and stretches out from through hole, and spring 8 lower end is connected with suction nozzle 7 top, and spring 8 top is connected with connector 11, stationary installation comprises fixed orifice and guide groove 13, and fixed orifice is arranged on bottom guide groove 13, and test board 1 can slide the relative position to regulate test board 1 and suction nozzle 7 in guide groove 13.
The course of work of this example: the operating physical force of operator is delivered to surface-mounted integrated circuit by handle 4, drive link 5, spring 8, suction nozzle 7 successively, and the downforce of surface-mounted integrated circuit equals the elastic force of spring 8.Elasticity coefficient due to spring 8 is definite value, and the compression travel of spring 8 is also definite value, therefore can draw, the elastic force of spring 8 is definite value, can ensure that the downforce of each test is identical; The downforce of manual test is consistent with the downforce of automatically testing to select the spring 8 of different elasticity coefficient to ensure according to the downforce of Auto-Test System, ensures the consistance of test result.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
