Description

Technical Field

[0001] This utility model relates to the field of PCBA aging test technology, specifically to an adjustable-angle PCBA aging test fixture. Background Technology

[0002] PCBA aging tests can simulate harsh working environments such as high temperature, high humidity, high voltage, and high current, accelerating the aging process of internal PCBA components and exposing potential quality problems in advance. Among these, the PCBA aging test fixture is a crucial piece of equipment for aging tests on PCBAs, playing a key role in the electronics manufacturing industry. However, PCBA aging test fixtures typically hold and fix multiple circuit boards, requiring them to be removed one by one after the aging test, which is time-consuming, labor-intensive, and inconvenient to use. Therefore, we propose an adjustable-angle PCBA aging test fixture. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an adjustable-angle PCBA aging test fixture. By setting clamping components and angle adjustment components, the fixture can be quickly unloaded without affecting its use, saving time and effort. At the same time, by setting pointers and degree scales, the angle can be precisely adjusted to simulate heat and stress distribution at different angles and detect potential failure points in advance.

In use, the set rotary motor can drive the test frame body and circuit board to rotate until the circuit board is vertically downward. Then, the set drive motor can drive several clamping plates to move synchronously through the lead screw until several clamping plates are completely detached from the circuit board. After detachment, multiple circuit boards will automatically fall off due to gravity, achieving the effect of rapid unloading, saving time and effort. At the same time, the rotation of the rotary motor can adjust the angle of the test frame body. During the adjustment process, the pointer can be aligned with the degree scale to precisely adjust the angle of the circuit board on the test frame body to simulate the heat and stress distribution at different angles and detect potential failure points in advance. In addition, the first and second mounting plates are detachable bolt-fixed plates to facilitate the disassembly and replacement of the test frame body. Attached Figure Description
