Embodiment Construction
[0034] like Figure 1-4 , as shown in 6-10, a printed circuit board testing device, including a conveyor belt 2 and baffles 1 arranged on both sides of the conveyor belt 2, the conveyor belt 2 is provided with multiple sections, and each section of the conveyor belt 2 is connected by connecting components. The assembly includes a first pressure plate 6, a second pressure plate 7 and a connecting plate 5 arranged between two adjacent conveyor belts 2. The first pressure plate 6 is arranged outside the second pressure plate 7 and is connected with the second pressure plate 7 through a first connection. The shaft 22 is rotatably connected, so that the first pressing plate 6 and the second pressing plate 7 can rotate relative to each other around the first connecting shaft 22, and the second pressing plate 7 and the connecting plate 5 are connected by a hinge 20, and the hinge 20 is set On the bottom surface of the second pressing plate 7 and the connecting plate 5, so that the se...

The invention discloses a printed circuit board testing device and a testing method thereof. The printed circuit board testing device comprises a conveyor belt and baffle plates arranged on both sides of the conveyor belt. The conveyor belt is provided with multiple sections, and each section of the conveyor belt is connected by The assembly is connected; the connecting assembly includes a first pressing plate, a second pressing plate and a connecting plate arranged between two adjacent conveyor belts. The first pressing plate is arranged outside the second pressing plate and rotates with the second pressing plate through the first connecting shaft. connection, the second pressure plate and the bottom surface of the connecting plate are connected by hinges; when the connecting plates on both sides of the second connecting shaft move upward in a V-shape, one side of the circuit board will be the first to connect with the first pressure plate and the second pressure plate. At this time, with the continuous inclination of the connecting plates on both sides, the other side of the circuit board will be gradually squeezed and raised, and finally be engaged with the chamfer between the first pressure plate and the second pressure plate. Therefore, The device can be positioned quickly and has a good fixation effect.
Description
technical field [0001] The invention relates to the technical field of circuit board testing, in particular to a printed circuit board testing device and a testing method thereof. Background technique [0002] With the development of electronic technology and printed circuit board manufacturing technology, current electronic products are becoming more and more complex, and the quality requirements for single-sided aluminum-based printed circuit boards are also getting higher and higher, especially to ensure that electronic products can be It can be used normally in the case of instantaneous overvoltage, etc. Before the finished printed circuit board is shipped, it needs to undergo strict high-voltage resistance testing. The test device is used to detect whether the single-sided aluminum-based printed circuit board is broken down within the set voltage range and whether the leakage current is less than the preset value of the leakage current. [0003] Chinese invention paten...
