Description

Technical Field

[0001] This utility model relates to the field of power module packaging and testing, and in particular to a power management chip packaging and testing device. Background Technology

[0002] A power management chip is an integrated circuit used to optimize and control the power usage of electronic devices. Its main functions include voltage conversion, power distribution, battery charging management, power consumption monitoring, and thermal management. It aims to provide efficient and reliable power solutions for various electronic devices such as smartphones, tablets, and embedded systems. To ensure the quality of power management chip packaging, push-pull force testers are required to perform solder ball shearing tests, wire bond pull tests, and chip shear strength tests.

[0003] The push-pull force tester consists of a body, operating lever, test fixture, cutting module, and microscope unit. However, existing push-pull force testers simply connect the microscope unit to a vertically adjustable mounting bracket during installation. This requires aligning the microscope unit with the test fixture, making initial installation time-consuming and laborious. Furthermore, after installation, the microscope unit only offers vertical adjustment, limiting the viewing angle. Therefore, this solution proposes a power management chip packaging testing device to address these issues. Utility Model Content

[0023] It also includes a testing mechanism, which is located in the middle of the push-pull force tester body 1. The testing mechanism is used for clamping and pushing-pull testing of the power management chip. Specifically, the testing organizations include: Test knife unit 2 is located on the inner wall of the top of the test port. An adjustable sliding mounting structure is provided on the inner wall of the top of the test port, which allows the test knife unit 2 with the corresponding knife head to be replaced according to the test requirements. Chip clamp 4 is located on the inner wall at the bottom of the test port. Chip clamp 4 is used to clamp the power management chip to be tested. The top of chip clamp 4 is provided with a clamping opening for clamping the power management chip. The clamping opening is symmetrically clamped by two sets of clamping plates. A screw adjustment structure is provided on the top of chip clamp 4 to adjust the movement of the two sets of clamping plates in opposite directions, thereby adjusting the opening size of the clamping opening. The bottom of chip clamp 4 is provided with a rotation adjustment mechanism so that the clamped power management chip can be rotated during testing.

The control chip of the push-pull force tester body 1 sends output commands to the driving part of the test blade unit 2, thereby controlling the test blade unit 2 to change position, so that the blade head of the test blade unit 2 can perform push-pull testing on the clamped power management chip during the movement.

[0025] Example 2: This utility model provides the following... Figure 4 and Figure 5 The mounting mechanism shown is applied to the power management chip packaging and testing device of Embodiment 1. The mounting mechanism includes a connecting part, a rotating part, and a mounting part. The connecting part is connected to the output end of the vertical moving unit 101.

The first fastening bolt 601 is used to compress and restrict the rotation of the connecting ball head 701. Through the rotational connection of the connecting ball head 701 at the top of the connecting ball cup 6, the connecting ball head 701 drives the connecting rod 7 to rotate when it rotates, so that the mounting part connected to the connecting rod 7 can rotate synchronously. When the first fastening bolt 601 moves closer to the connecting ball cup 6, the threaded end of the first fastening bolt 601 is pressed against the outer wall of the connecting ball head 701, so that the connecting ball head 701 is compressed and restricted, thereby enabling positioning after rotation adjustment.
