The storage environment of humidity sensitive components and chips should be kept at about 25 ℃ and relative humidity (RH)<40%. If the temperature and humidity of the storage and operation environment is higher than the standard range, it is necessary to control the folding control of humidity sensitive components and chips. There are still some gaps that may not be visible to the naked eye, but when the integrated circuit chip is placed in the environment, the water in the environment will penetrate into the chip by osmosis. The chip is affected by moisture. In order to improve your understanding of chip baking, the following is the relevant content of core detection and sorting, hoping to bring you reference and help.

The failure analysis of electronic components is to confirm the failure phenomenon of electronic components, distinguish the failure mode and failure mechanism, and finally confirm the failure reason with the help of various test and analysis technologies and analysis procedures. Put forward suggestions to improve the design and manufacturing process, prevent the recurrence of failures and improve the reliability of components. Therefore, to carry out failure analysis, it is necessary to establish a collection system of failure information and failure devices at the stages of development, production and engineering.

Non-destructive testing is a method that uses physical or chemical methods and advanced technology and equipment to inspect and test the internal and surface structure, performance and state of the test piece without damaging the test piece. It is a method to inspect and test the structure, property, state and defect type, quality, quantity, shape, position, size, distribution and change of the internal and surface of the test piece by means of physical or chemical methods and modern technology and equipment, using the change of thermal, acoustic, optical, electrical, magnetic and other reactions caused by the internal structure abnormality or defect of the material.

In the formal industrial production, there are special screening and testing workshops for components, which are equipped with many general and special screening and testing equipment and instruments. For example, if they are not screened and tested before installation, once they are welded into the printed circuit board, it is found that the circuit cannot work properly, and then go to check, which not only wastes a lot of time and energy, but also is easy to damage the components and printed circuit board by disassembling.
