Description

Circuit test vibration device

The invention relates to a circuit testing device, in particular to a testing device for testing whether a signal line of an electronic component has a short or broken circuit.

At present, a combination of various modules has been widely used in electronic devices to realize various functions, and each module is connected to a motherboard through various signal lines to achieve mutual transmission of various data signals. Signal lines include flexible boards, cables or cables.

In view of the fact that the quality of the signal line plays an extremely important role in the use of electronic devices, the electronic components and functional modules in the electronic device need to rely on various signal lines to maintain the transmission and reception of signals, and the signal lines are poor due to poor quality control. In the case of a disconnection or short circuit, some or all of the functions of the electronic device will be invalidated. Therefore, in order to ensure the normal operation of the signal line, the signal line will be electrically tested beforehand to ensure that the quality of the signal transmission is good.

The existing test method for signal lines is designed to be tested by a set of test fixtures. Generally, the test fixture has one or more sets of connection interfaces for connecting the object to be tested, that is, at least one end of the signal line. After inputting current from one of the connection interfaces, the current is passed through the object to be tested and then returned to another connection interface or a part, such as an IC or an LED lamp, thereby measuring the resistance value of the object to be tested. If the measurement result is abnormal, it means that the object to be tested has an abnormal situation such as short or open circuit, and it is necessary to determine the defective product, thereby achieving the purpose of detection.

However, the current detection method only fixes the two ends of the object to be tested in a fixed manner, and since the object to be tested also has a plurality of transmission wires at the same time, especially the defective product is easy to cause the transmission guide during the bending process. The breakage of the line causes the signal line to be short and open. The existing test device cannot detect whether the object under test is still in a normal path state under the condition of bending or deformation, so that there is a need for positive improvement.

Therefore, in order to effectively overcome the aforementioned drawbacks, the present invention provides a circuit test vibration device that generates intermittent force or vibration to the object to be tested, and causes the object to be tested to generate intermittent reciprocating vibration or deformation bending.

Another object of the present invention is to provide a dynamic electrical test of a test object to detect an electrical test of the test object while it is dynamic.
