Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic component testing, in particular to a testing device for electronic components. BACKGROUND

[0002] Electronic components refer to various components used in electronic circuits, such as resistors, capacitors, inductors, diodes, and transistors, which have independent electrical functions and can be fixed on a PCB through welding or other means, and connected to the circuit on the PCB through wires, pads, etc., to form a complete electronic circuit. After the electronic components are installed on the PCB, they need to be tested, which usually includes appearance inspection, functional testing, and corrosion resistance testing, etc. Among them, corrosion resistance testing of electronic components is a testing method that simulates a specific corrosion environment to evaluate the corrosion resistance of electronic components in an environment containing acetic acid salt mist, so that electronic components can be suitable for special environments such as coastal areas.

[0003] Currently, some electronic components are tested for corrosion resistance by placing the PCB with the electronic components installed in a salt spray machine to test the corrosion resistance of the electronic components on the surface of the PCB by simulating a specific corrosion environment. During the testing process, the worker can take out the PCB according to the specified time and observe the state of the PCB surface to judge the corrosion resistance of the electronic components. When the worker opens the cover of the salt spray machine, the external environment affects the inside of the salt spray machine, at which time the environment for corrosion resistance testing is destroyed, and the worker needs to replace the PCB and perform the next batch of testing operation. When the worker tests the corrosion resistance of the electronic components for different lengths of time, the salt spray machine needs to be used multiple times and different batches of PCBs need to be tested, which is time-consuming and can affect the efficiency of the testing operation. In addition, some salt spray machines are provided with a liquid storage tank for storing salt water. During testing, the salt water in the liquid storage tank is discharged through a fogging device to test the electronic components on the surface of the PCB. After the testing operation is completed, the remaining salt water in the liquid storage tank can cause sedimentation, which can affect the results of subsequent testing operations. In addition, the position of the fogging device in some current salt spray machines is relatively stable. When it is used, the salt mist is sprayed from one side of the inside of the salt spray machine, spreads and contacts the surface of the electronic components. Therefore, the test results of some electronic components can be affected by their position. SUMMARY

[0004] The present invention aims to provide a testing device for electronic components, which can perform a preliminary test on the stability of the electronic components mounted on the surface of a PCB while ensuring that the electronic components can be more fully contacted with salt spray.
