Description

Technical Field

[0001] The invention relates to a conductivity testing tool for a rigid-flexible board. Background Art

[0002] Before the rigid-flex board leaves the factory, its wiring and impedance need to be tested. The common testing method is to connect a current of a certain voltage and then detect whether each component is operating normally.

[0003] Existing testing is often based on the proficiency of employees and their own judgment to perform fault detection on rigid-flex boards, which can be summarized as "looking, listening, smelling and touching".

[0004] "Look" means to check whether the components have any obvious mechanical damage, such as cracks, burnt black, deformation, etc.; "Listen" means to listen to whether the working sound is normal, for example, something that shouldn't be making noise is making noise, something that should be making noise is not making noise, or the sound is abnormal, etc.; "Smell" means to check whether there is any peculiar smell, such as the smell of burning, the smell of capacitor electrolyte, etc.

[0005] An experienced electronic repairman is very sensitive to these smells; "touch" means to use your hands to test whether the temperature of the device is normal, such as too hot or too cold. Some power devices will generate heat when working. If they feel cold to the touch, it can basically be judged that it is not working. But if the place that should not be hot is hot or the place that should be hot is too hot, it is not good.

[0006] However, with the development of industrial modernization, manual testing is often not very reliable. Therefore, a dedicated testing tool is needed to collect test data on behalf of employees to improve the reliability of testing. Summary of the invention

[0007] The purpose of the present invention is to solve the above deficiencies in the prior art and to provide a conductivity testing tool for a rigid-flex board.

[0008] A conductivity testing tool for a soft-hard combination board, comprising a base plate and a mounting plate; the base plate is connected to the mounting plate through a plurality of support columns; the mounting plate comprises an outer frame, the outer frame is connected with a plurality of connecting tubes distributed in a horizontal and vertical array, and a dovetail groove is provided on the outer wall of the outer frame; a plurality of temperature sensors are provided on the mounting plate, the temperature sensors are embedded in a movable bracket, the lower surface of the movable bracket is provided with two mutually parallel claws, the inner diameter of the claws matches the outer diameter of the connecting tube; a plurality of clamping devices are provided on the upper surface of the mounting plate, the clamping devices comprise a connecting beam and two mutually parallel sliders, the side walls of the sliders are inserted in the dovetail grooves, the upper ends of the two sliders are connected through the connecting beam, a plurality of hold-down bolts are provided on the connecting beam, the hold-down bolts are screwed to the connecting beam through threads, and a polyurethane cushion is connected to the bottom of the hold-down bolts.

[0009] Preferably, the number of the clamping devices is two.

[0010] Preferably, two hold-down bolts are provided on each of the connecting beams.

[0011] Preferably, the outer surface of the hold-down bolt is a knurled surface.

[0012] Preferably, the number of the support columns is six.

[0013] Beneficial effects:

[0014] During the test, the temperature sensor is installed at the designated position, and then the rigid-flex board is covered on the upper surface of the mounting plate, and the clamping device is slid so that the downward bolts press the four corners of the rigid-flex board. At this time, the temperature sensor is located directly below the important part of the rigid-flex board, and then the switch is started to power the rigid-flex board and monitor the index changes of each temperature sensor, so as to conduct reliable and all-round detection of the rigid-flex board. Compared with the traditional detection method based on personnel experience, the use of dedicated detection tools has better stability and higher reliability. BRIEF DESCRIPTION OF THE DRAWINGS
