Description
Technical field
The present invention relates to ic test technique field, specifically a kind of multi-angle rotation for the test of Die shear power
Turn fixture.
Background technology
IC chip needs to carry out various tests after preparing, and shearing force testing is a kind of to chip
Mechanical test.At present, chip is fixed on shear-force tester generally by fixture and tested, but the direction of chip
It is not necessarily all regular, some are inclined, and the deviation of angle is so there is after shear-force tester is installed on, and cause to cut
The test error of shear force.
The content of the invention
It is an object of the invention to provide a kind of multi-angle rotary fixture for the test of Die shear power, the fixture can
Test chip is rotated, changes angles, puts chip regular, ensures that shearing force testing result is accurate.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of multi-angle rotary fixture for the test of Die shear power, including upper clamp and lower clamp, upper clamp top are provided with
Rectangular channel, upper clamp lateral are equipped with the regulating bolt coordinated with upper clamp screw thread, and rectangle is stretched into regulating bolt the inner
Groove is simultaneously connected with chip clamping plate, and chip clamping plate can be formed with rectangular channel to be coordinated；Upper clamp bottom is provided with cylindrical protrusions；Under
It is provided with the top of clamp and forms the cylinder shape groove coordinated with the cylindrical protrusions, lower clamp lateral is equipped with and lower clamp
The fixing bolt that screw thread coordinates, fixing bolt the inner can be formed with the side wall of cylindrical protrusions to be coordinated；Lower clamp bottom is provided with
In the fixture block of cuboid, fixture block is used for and shear-force tester coordinates installation.
Further, also horizontal connection has handle on the outside of the upper clamp.
The invention has the advantages that upper clamp by chip to be measured by chip Boards wall, by cylindrical protrusions and
Cylinder shape groove, upper clamp can rotate horizontally on lower clamp, so as to change the angles of chip, chip is put rule
It is whole, it ensure that shearing force testing result is accurate.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention；

Embodiment
As shown in figure 1, the present invention provides a kind of multi-angle rotary fixture for the test of Die shear power, including upper clamp
1 with lower clamp 2, with reference to shown in Fig. 2 and Fig. 3, the top of upper clamp 1 is provided with rectangular channel 1a, the lateral of upper clamp 1 be equipped with and
The regulating bolt 3 that the screw thread of upper clamp 1 coordinates, the inner of regulating bolt 3 stretches into rectangular channel 1a and is connected with chip clamping plate 4, chip gripper
Plate 4 can be formed with rectangular channel 1a to be coordinated；The also horizontal connection of the outside of upper clamp 1 has handle 1c, and the bottom of upper clamp 1 is provided with cylinder
Raised 1b.
With reference to shown in Fig. 4 and Fig. 5, the top of lower clamp 2 is provided with forms the cylindrical recessed of cooperation with the cylindrical protrusions 1b
Groove 2a, the lateral of lower clamp 2 are equipped with the fixing bolt 5 coordinated with the screw thread of lower clamp 2, and the inner of fixing bolt 5 can be with circle
Column-shaped projection 1b side wall, which is formed, to be coordinated；The bottom of lower clamp 2 is provided with the fixture block 2b in cuboid, and fixture block 2b is used for and shearing force is surveyed
Try instrument and coordinate installation.
In use, this rolling clamp is fixed on shear-force tester by fixture block 2b, chip to be measured is then put into square
Shape groove 1a, regulating bolt 3 is threaded in or out, drives chip clamping plate 4 to be moved horizontally in rectangular channel 1a, adjustment chip clamping plate 4
Position, chip to be measured is set to be clamped and fixed.Now, as the putting position of fruit chip is unsatisfactory for requiring, then turned by handle 1c
Dynamic upper clamp 1, by cylindrical protrusions 1b and cylinder shape groove 2a cooperation, makes upper clamp 1 be rotated horizontally on lower clamp 2,
So as to drive chip to rotate together, reach the purpose of adjustment chip angles, put chip regular；Fixing bolt 5 is tightened,
Upper clamp 1 is fixed, can be carried out shearing force testing afterwards, ensure that the accuracy of shearing force testing result.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention；Appoint
What those skilled in the art, without departing from the scope of the technical proposal of the invention, all using the side of the disclosure above
Method and technology contents make many possible changes and modifications to technical solution of the present invention, or are revised as the equivalent reality of equivalent variations
Apply example.Therefore, every content without departing from technical solution of the present invention, the technical spirit according to the present invention are done to above example
Any simple modification, equivalent substitution, equivalence changes and modification, still fall within the range of technical solution of the present invention protects.
