Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of accelerated aging test equipment, in particular to a foldable sample test support of an accelerated aging test chamber. BACKGROUND

[0002] The accelerated aging test chamber is used for testing the moisture resistance of products. The product to be tested is placed in a harsh temperature, humidity and pressure environment for testing. Moisture can penetrate the package along the interface between the gel or gel and the lead frame, thereby detecting the sealing performance of the product and testing its pressure resistance.

[0003] The conventional accelerated aging test equipment generally uses a fixed layer plate. Since the accelerated aging test chamber is an electrically charged test during use, a large amount of precise manual wiring work is required. The fixed layer plate is generally fixed in the cavity and requires a large amount of operation space for wiring, which reduces the efficiency of the equipment. In the wiring process, only one open surface is used for wiring, making the wiring operation very difficult. The small space greatly affects the quality of the wiring, and the test results are often inaccurate due to wiring problems. In addition, the fixed support and layer plate are not easy to clean, which can cause cross-contamination between batches of test samples, affecting the test results. Moreover, the large test plate is placed flat, which is prone to condensation. The water stains stay on the circuit board for a long time, which can easily cause short circuits or even burn out of the test sample.
