Description

Technical Field

[0001] The utility model belongs to the technical field of bearing devices, and in particular relates to a universal bearing device for push-pull force testing in a semiconductor packaging process. Background Art

[0002] During welding, transportation, and use, electronic devices will usually generate mechanical stress on the solder joints or devices due to vibration, impact, bending, and deformation, resulting in failure of the solder joints or devices. Push-pull force tests are usually used to simulate mechanical failure models, and the firmness of the solder joints is detected by the push-pull force values ​​and phenomena after the test. This is to prevent the chip from falling off the base island or the solder wire from falling off the solder position during the product manufacturing process and subsequent transportation and use. The current practice is to perform push-pull force tests on the adhesion between the chip and the base island after the chip is assembled on the base island or after the wire is bonded, to verify whether the chip and the base island, the solder wire and the solder position meet the required bonding strength during use.

[0003] The existing clamping fixture is specially designed according to the structural shape of each semiconductor product. It is only suitable for a single type of product and cannot be used universally. In addition, the design and processing cycle of the fixture is long, and it is frequently replaced during use, resulting in low production changeover efficiency.

[0010] Under the sliding action of the first slider and the slide rail, the movable inner rod can cooperate with the elastic potential energy of the reset spring to move up and down smoothly inside the limiting slot, ensuring the stability and efficiency of the device during use.

[0025] The side pull plate 7 is pulled upward and downward under the action of the elastic potential energy of the return spring 11, and the limit plug rod 6 is pulled to the maximum limit value. At this time, the docking block 5 is inserted into the inner side of the plug slot 4. After the insertion between the two groups of plug slots 4 and the docking block 5 is completed, the side pull plate 7 is loosened again, so that the inner top end of the limit plug rod 6 passes through the outer wall of the side mounting plate 13 and is inserted on the outer wall of the docking block 5, and the installation work between the side mounting plate 13 and the clamping plate 15 is completed.
