In order to ensure that the purchased electronic components are brand new and original, we will conduct quality inspections for each electronic component to determine whether the product is qualified.
1. Functional test
There are many different packages for electronic components. We have many different test procedures. Not all of them are shown in the video. Take DIP package as an example.
2. Appearance test
Perform appearance inspection under a 500-fold microscope and perform appearance test with acetone to ensure that the product is not a counterfeit product
