What are the aspects of appearance quality inspection of electronic components?

Date:2022-10-20 16:35:02Views:763

There are many electronic components, such as resistors, capacitors, chips, diodes and transistors. The application fields of electronic components are also very wide, such as thyristor (silicon controlled rectifier), inductance coil, transformer, crystal oscillator, earphone, resistor, capacitor, etc., which all use electronic components. Any product will have some bad appearance during production, and electronic components are no exception. How to check the appearance quality of electronic components? If you are interested in the content to be covered in this article, please read on.

How to check the appearance quality of electronic components?

The following operations shall be followed when identifying and testing electronic components:

1. The model, specification, manufacturer and place of origin of components shall be checked to ensure that they conform to the design requirements and the external packaging is intact.

2. The electrode leads of electronic components shall be free of crimping and bending, and the coating shall be intact, smooth and free of oxidation and rust.

3. Check whether the appearance of electronic components is intact, whether there are defects such as dents, scratches and cracks on the surface, and whether the components with coating on the outside are free of falling off and scratches.

4. The model and specification marks on the electronic components shall be clear and complete, the color code position and color shall meet the standards, and the characters on the integrated circuit shall be carefully checked.

5. The size of components of mechanical structure shall be qualified, the thread shall be flexible, and the rotation feel shall be appropriate.

6. Switch components can be operated flexibly and have good hand feel; The tightness of connectors shall be appropriate and the contact shall be good.

So today's content is shared here. The components in various electronic products have their own characteristics. The inspection content should be determined according to the specific requirements of each component. Our company has a team of professional engineers and industry elites, and has built three standardized laboratories with an area of more than 1800 square meters, which can undertake a variety of test projects such as electronic component test verification, IC authenticity identification, product design material selection, failure analysis, functional testing, factory incoming material inspection and tape weaving.
