Description

Technical Field

[0001] This utility model relates to the field of aging test extension boards, and in particular to an aging test extension board. Background Technology

[0002] Aging test expansion boards are auxiliary circuit boards used to expand the aging test channels of electronic devices. They can be adapted to chips, modules and other test devices of different specifications. They can simultaneously apply electrical stress and environmental stress to multiple devices, accelerate the exposure of potential defects, and improve the efficiency of aging tests. They are commonly used expansion tools in the reliability verification of electronic products.

[0003] Most existing aging test expansion boards adopt a fixed module design with a fixed number of test ports, which cannot be flexibly adjusted according to the number of products under test. When the testing requirements change, it is often necessary to replace the entire equipment, which is not only cumbersome to operate, but also increases the cost of equipment use. Therefore, those skilled in the art provide an aging test expansion board to solve the problems mentioned in the background art. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-4 One embodiment of this utility model is an aging test extension board, which includes an extension board body 1, a plurality of extension mechanisms 2 are provided on the upper end of the extension board body 1, and a control mechanism 3 is provided inside the extension board body 1.

[0018] Specifically, the expansion board body 1 is the basic carrier, the expansion mechanism 2 can insert different test modules 202 to realize functional expansion, and the control mechanism 3 isolates, converts and controls the transmission of test signals. All parts work together to make aging tests more efficient and accurate.

[0019] Reference Figures 1-3 The expansion board body 1 includes a first board 101, a second board 102 fixedly connected to the upper end of the first board 101, a first socket 103 fixedly provided at one end of one side of the second board 102, a second socket 104 fixedly provided at the middle position of one side of the second board 102, and a third socket 105 fixedly provided at the other end of one side of the second board 102. The expansion mechanism 2 includes multiple slots 201 and multiple test modules 202. Multiple test ports 203 are provided at the upper end of each of the multiple test modules 202. Multiple slots 201 are fixedly provided at the upper end of the second board 102. Multiple test modules 202 are inserted into the slots 201.

[0020] Specifically, in the expansion board body 1, the first board 101 and the second board 102 constitute the structural foundation of the expansion board body 1. The first socket 103, the second socket 104 and the third socket 105 are used to connect external devices or power supplies. In the expansion mechanism 2, the slot 201 provides a plug-in position for the test module 202. By combining different numbers and types of test modules 202, the number of test ports 203 can be flexibly expanded to 32-64. For example, by inserting 8 test modules 202 equipped with 8 test ports 203, 64 products can be tested simultaneously, fully meeting the needs of large-scale testing.

[0021] Reference Figure 3 , Figure 4 The control mechanism 3 includes a controller 303 and an adapter 304. The controller 303 is equipped with multiple isolation transformers 301 and optocouplers 302 on its upper end. One side of the adapter 304 is fixedly connected to the controller 303 via a flexible circuit board, and the other side of the adapter 304 is connected to the first socket 103, the second socket 104 and the third socket 105 via a pin connector.

[0022] Specifically, in control mechanism 3, isolation transformer 301 provides electrical isolation for the input power supply to prevent interference, optocoupler 302 achieves isolated signal transmission and improves signal stability, controller 303 processes and controls the test process, and adapter 304 is connected to controller 303 through a flexible circuit board and docks with each socket through a pin connector to realize the transfer and transmission of signals and power.

[0023] Working Principle: During aging tests, users can insert different quantities and types of test modules 202 into the slots 201 at the top of the second board 102 according to the number of products under test and testing requirements. For example, to test 32 products simultaneously, four test modules 202 equipped with eight test ports 203 can be inserted; to test 64 products, eight similar test modules 202 can be inserted, quickly expanding the number of test ports 203. Different types of test modules 202 can also specifically perform voltage aging, temperature aging, and other testing functions. Each test module 202 connects to the device under test through the test ports 203. External devices or power supplies are connected to the expansion board through the first socket 103, the second socket 104, and the third socket 105. The power supply first passes through the isolation transformer 301 in the control mechanism 3, which electrically isolates the input power to prevent external power interference from affecting test accuracy. Simultaneously, signal transmission during the test is isolated through the optocoupler 302, using optical signals to transmit information and cutting off the electrical connection between input and output to prevent signal interference. To mitigate noise impact and ensure the purity and stability of signals transmitted simultaneously through numerous test ports 203, the controller 303, acting as the control core, controls and manages the entire testing process according to the preset test program. It sends control commands to each test module 202, enabling them to perform aging tests on the equipment as required, and simultaneously receives and analyzes test data from multiple test modules 202. The adapter 304 connects to the controller 303 via a flexible circuit board and to each port via a pin connector, accurately transmitting externally input signals and power to the corresponding test modules 202 and the controller 303, ensuring stable signal and power transmission during large-scale testing. When testing requirements change, simply removing the existing test modules 202 from the slot 201 and replacing or adding different types and quantities of test modules 202 allows for rapid adjustment of testing functions and the number of test ports 203. Throughout the aging test process, the control mechanism 3 ensures stable test operation, while the expansion mechanism 2 meets diverse testing needs, enabling the aging test expansion board to efficiently and reliably complete aging tests on equipment of different scales.
