Background

The salt spray test is a reliability test for placing electronic components in a salt spray test box simulating a salt spray environment, continuously fumigating NaCl solution for the electronic components and investigating the salt spray corrosion resistance of products.

In the prior art, generally, an operator ties up a circulator/isolator product by using a salt spray corrosion resistant wire such as an enameled wire and a nylon wire and hangs the circulator/isolator product in a salt spray test box.

The existing binding wire test method has the following defects:

1. the wire binding efficiency is low, which is not beneficial to the reliability test of large-batch products;

2. part of circulator/isolator products have complex structures and no wire clamping positions, and the wire binding suspension method has the risk of unstable binding of the products and the products falling into the NaCl solution;

3. the cost of the enameled wire is high, and the wire rod is consumed by the salt spray test in the wire binding method, so that the test cost is increased;

4. the wire binding method is complex in operation and requires certain experience of an operator.
