Description

Technical Field

[0001] This utility model relates to the technical field of PCBA aging test carrier devices, and in particular to a quick-change PCBA aging test carrier device. Background Technology

[0002] In the electronics manufacturing industry, the quality and reliability of PCBAs directly determine the performance and market competitiveness of electronic products. As a key step in the PCBA quality inspection process, aging testing can effectively screen out products that fail early and significantly reduce the failure rate of products during user use. By simulating the extreme working environments that PCBAs may encounter in actual use, such as high temperature, high humidity, and high load, aging testing can accelerate the exposure of potential defects, such as component parameter drift, poor solder joints, and short circuits or open circuits. For example, in the PCBA aging test of smartphones, simulating long-term call and high-load gaming scenarios can detect crashes and restarts caused by unstable electronic component performance and poor soldering in advance, thereby improving the reliability of the phone. At the same time, with the rapid pace of electronic product updates, the types and specifications of PCBAs are becoming increasingly complex, with different pin layouts, interface types, and sizes. Traditional carriers can usually only adapt to a few specific PCBA models. Once the product model changes, a completely new carrier needs to be redesigned and manufactured, which is costly and time-consuming.

[0003] Currently, PCBA aging test carriers on the market mainly consist of a general-purpose base platform and replaceable subcarriers. Traditional PCBA aging test carriers have revealed many drawbacks when facing the trend of multi-variety, small-batch production. First, the changeover efficiency is extremely low. Past carriers were mostly customized designs for specific PCBA models, with fixed structures. When switching to test different PCBA models, the entire carrier often needs to be disassembled and reassembled, involving tedious screw removal and component replacement operations. The entire process is time-consuming, typically taking several hours or even longer for a single changeover. While replaceable subcarriers on the market can solve the problem of low changeover efficiency to some extent, traditional carriers use an integral rigid structure, with the subboard and base fixed by a screw array. Furthermore, the probe module, fixture components, and subboard are integrated. When changing to test different PCBA models, each fixing screw must be unscrewed, the old subboard removed, and the base contact surface cleaned, a time-consuming process. Utility Model Content

If the fixing plate can slide out of the fixing block under the same force, it is judged as qualified; otherwise, it is unqualified. This realizes the testing of the aging degree of the circuit board, and while ensuring automation, the test results can be seen more intuitively. Attached Figure Description

[0039] Working principle: Support blocks 3 are fixed on the top left and right sides of the mother plate 4. After the support blocks 3 are installed, they are used to support the mother plate. At the same time, the limiting shafts 6 fixed at the four corners of the bottom of the support blocks 3 can be engaged with the corresponding positions on the inner wall of the mother plate 4, achieving the function of positioning and limiting at the same time. Meanwhile, after the insertion plates 10 fixed on the bottom front and rear sides of the daughter plate 5 are inserted into the inner wall of the mother plate 4, the locking sleeves 7 fixed on the front and rear sides of the inner wall of the mother plate 4 have locking shafts 8 sliding on their inner walls. The locking shafts 8 can be engaged in the locking holes 11 opened on the insertion plates 10 under the elastic action of the spring 9, thereby realizing the quick installation of the daughter plate 5. At the same time, by sliding and adjusting the locking shafts 8, the daughter plate 5 can be disengaged. While satisfying the needs of quick changeover, the operation is simple and stable, ensuring the efficiency of testing.

[0040] To make the test results more intuitive, springs 205 are fixedly connected to the bottom left and right sides of the sub-board 5. The other end of spring 205 is fixed to the bottom of the inner wall of the placement box 201. The telescopic rod 203 fixed to the top of the support column 202 can drive the extrusion plate 204 to perform an extrusion test on the circuit board mounted on the top of the sub-board 5. At the same time, the fixing plate 207 fixed to the bottom of the sliding shaft 206 slides downward in the inner wall of the fixing block 208. If the fixing plate 207 can slide out of the fixing block 208 under the same force, it is judged as qualified; otherwise, it is unqualified. This realizes the aging test of the circuit board and, while ensuring automation, allows for a more intuitive view of the test results.
