Description

A jig for impact testing of hybrid integrated devices packaged in metal casings

technical field

The utility model relates to a jig for experimenting with electronic components, in particular to a jig for impact experiments with metal casings and hybrid integrated devices.

Background technique

Shock test is an important means to assess the shock resistance of hybrid integrated devices. In the impact test, the device is tested by installing the fixture on the test bench, so the quality of the fixture design is very important. The existing jig used for the impact test of hybrid integrated devices packaged in metal shells usually adopts the upper and lower halves of the cavity structure made according to the shape of the device shell. During the test, the device to be tested is placed in the cavity, the upper and lower halves are clamped together with bolts, and then installed on the test bench for testing. There are many defects in this structural fixture: 1. A kind of device housing must be made corresponding to a kind of fixture, which cannot be used universally, and the cost is high. 2. The production cycle of the fixture is long. When there is no corresponding fixture for a new shell, the test work will be delayed. 3. Due to the shape and size of the device shell, the shape and size of the cavity cannot be absolutely accurate, there are often clearance problems during clamping, and the clamping quality is poor. 4. Large volume, complicated clamping and low efficiency.

Utility model content

Aiming at the deficiencies of the prior art, the utility model designs and develops a clamp for impact testing of hybrid integrated devices packaged in metal shells, which can be used universally, has high clamping quality, and can greatly improve work efficiency.

The utility model is achieved through the following technical solutions:

A fixture for the impact test of hybrid integrated devices packaged in metal shells. A mounting plate with multiple columns and rows of bolt holes is provided on the table of the impact test bench. The hybrid integrated device is placed on the mounting plate. There is a pressing plate, and a through hole is opened on the pressing plate, through which the bolt is screwed into the screw hole of the mounting plate and the hybrid integrated device is pressed between the pressing plate and the mounting plate.

A jig for impact testing of hybrid integrated devices packaged in metal shells, the mounting plate is provided with a vertical plate with multiple rows and rows of bolt holes, the pressure plate is connected to the vertical plate by bolts, and the hybrid The integrated device is compressed between the pressure plate and the vertical plate.

The utility model relates to a jig for the impact test of a hybrid integrated device packaged in a metal case, and a groove for avoiding the protruding part of the hybrid integrated device is opened on the pressing plate.

The mounting plate of the clamp kit of the utility model is connected on the impact platform, so that it becomes a part of the impact platform. During the test, the pressure plate is screwed through the pressure plate into the screw hole on the mounting plate through a bolt of appropriate length, so that the hybrid integrated device is clamped between the pressure plate and the mounting plate. Since there are multiple rows and rows of screw holes on the mounting plate, the hybrid integrated device can be pressed on any position on the mounting plate through the pressing plate to meet the needs of different experiments. Compressing the hybrid integrated device on the vertical plate of the mounting plate can facilitate the other two axial impact tests. The pressure plate is provided with grooves to avoid protruding leads of various column widths of hybrid integrated devices, and is also suitable for dual in-line housing packaged devices. So it has extremely wide versatility. At the same time, the installation is simple. After the experiment is completed, the main thing is to loosen the bolts and take out the hybrid integrated device that has been tested, and then the next experiment can be carried out, which also greatly improves the working efficiency of the experiment.

Detailed ways

See accompanying drawing 1,2 shown.

The utility model is a jig for the impact test of a hybrid integrated device packaged in a metal shell. A mounting plate 7 with multiple columns and rows of bolt holes is provided on the table 6 of the impact test bench, and the hybrid integrated device 4 is placed on the mounting plate 7. Above, the hybrid integrated device 4 is provided with a pressure plate 3, and the pressure plate 3 is provided with a through hole 2, and the bolt 1 is screwed into the screw hole 5 of the mounting plate 7 through the through hole, and the hybrid integrated device 4 is pressed on the pressure plate 3 and mounting plate 7. The mounting plate 7 is also provided with a vertical plate 9 with multiple rows and rows of bolt holes, the pressure plate 3 is connected to the vertical plate 9 through bolts 1, and the hybrid integrated device 4 is pressed between the pressure plate 3 and the vertical plate 9 for Carry out the other 2 axial impact tests. The pressing plate 3 is provided with a groove 8 for avoiding the protruding part of the hybrid integrated device 4 . During the test, the pressure plate 3 is screwed into the screw hole 5 on the mounting plate 7 through the bolt 1 of an appropriate length through the pressure plate 3 , so that the hybrid integrated device 4 is clamped between the pressure plate 3 and the mounting plate 7 . Since multiple rows and columns of screw holes 5 are provided on the mounting plate 7, the hybrid integrated device 4 can be pressed on any position on the mounting plate 7 through the pressing plate 3, so as to meet the needs of different experiments. The other two axial impact tests can be conveniently performed by pressing the hybrid integrated device 4 on the vertical plate 9 of the mounting plate 7 . The pressure plate 3 is provided with a groove 8 to avoid the protruding part of the hybrid integrated device 4, and is suitable for various forms of metal casing packaging devices. So it has extremely wide versatility. At the same time, the installation is simple. After the experiment is completed, as long as the bolt 1 is loosened to take out the hybrid integrated device 4 that has been tested, the next experiment can be carried out.
