Description

Technical Field

[0001] This utility model relates to the field of pressure resistance testing device technology, and more specifically to a multi-parameter integrated pressure resistance testing board. Background Technology

[0002] After the production of the PCB to be tested is completed, a withstand voltage testing device is needed to test whether the PCB meets various performance characteristics. Only after passing the test can it be shipped for sale. Insulation and withstand voltage are important technical indicators in PCB production, reflecting the PCB's electrical resistance. Insulation: The insulation resistance between mated or unmated contacts and adjacent contacts, as well as between any contact and the shell, is the test indicator. Withstand voltage: (also known as dielectric withstand voltage) The test is conducted between PCB contacts or between any contact and the shell under a certain voltage and time without breakdown or arcing. Therefore, factory inspection requires quality testing of the insulation and withstand voltage of each PCB to ensure that the product meets the factory standards and technical conditions. In addition to the above two withstand voltage tests, the PCB also needs to be connected to an external power source for power-on testing to ensure that the PCB meets the product requirements. In existing technologies, PCB insulation and withstand voltage testing are typically performed using automated testing equipment. The conventional approach involves placing the PCB under test into a test fixture, then clamping it, connecting test points, powering it on, and observing the instruments. However, after insulation and withstand voltage testing, the PCB needs to undergo power-on testing to meet factory requirements. Current testing methods involve separate testing, which is time-consuming, labor-intensive, and increases the workload for workers. To address this, the inventors propose a multi-parameter integrated withstand voltage test board. This board is mounted on a testing platform and consists of two layers: the upper layer performs insulation and withstand voltage tests, while the lower layer performs power-on tests. This enables multi-parameter testing of the PCB and improves testing efficiency and quality.

[0003] To improve the efficiency and safety of PCB withstand voltage testing and achieve automated testing, Chinese Patent (Authorization Announcement No.: CN222896238U) discloses a dual-station staggered transfer testing platform for PCBs. This utility model includes two top plates, two bottom frames, and multiple bottom columns. The top plates are fixedly connected at their adjacent sides. The tops of the two bottom frames are respectively fixedly connected to the bottoms of the two top plates. The bottoms of the two bottom frames are fixedly connected to one end of each of the multiple bottom columns. A U-shaped frame is fixedly connected to the top of each of the two top plates. Test slots for easy testing are provided on the tops of both top plates. A lifting mechanism is mounted on the U-shaped frame to facilitate PCB testing. A moving mechanism is mounted on the test slots to move the PCB. This utility model achieves precise lifting and horizontal movement of the PCB, facilitating testing. Simultaneous testing at two stations improves PCB testing efficiency and reduces time and effort consumption.

[0004] The solution still has some shortcomings in application. Since PCB withstand voltage testing includes insulation and withstand voltage testing, it also needs to be tested under power-on conditions. However, the PCB itself does not have its own power supply, so an external withstand voltage test board is required to perform power-on testing and enable the PCB to perform multi-parameter testing. Therefore, the structure of the withstand voltage test board needs to be improved to overcome the aforementioned limitations, make it more in line with actual testing needs, improve testing efficiency, and further enhance practical performance.
