MOS tubes are metal oxide semiconductor field effect transistors, or metal insulator semiconductor. The source and drain of MOS tube can be exchanged. They are both N-type regions formed in the P-type background. To correctly test and judge whether MOSFET fails, the key is to find the reason behind the failure and avoid making the same mistake again. This paper has collected and sorted out some data, hoping to be of great reference value to all readers. View >>

The full name of EMC test (electromagnetic compatibility test) is Electro Magnetic Compatibility, which is defined as the ability of equipment and systems to work normally in their electromagnetic environment without causing unbearable electromagnetic interference to anything in the environment. Therefore, the EMC test includes two requirements: on the one hand, the electromagnetic interference generated by the equipment to the environment during normal operation cannot exceed a certain limit; On the other hand, it means that the appliance has a certain degree of immunity to electromagnetic interference existing in the environment, that is, electromagnetic sensitivity.

High temperature and high humidity test is to simulate the temperature and humidity environment in which products are stored and operated, and to check whether the impact on products after a period of time under this environment is within the acceptable range. The product storage and working environment has a certain temperature and humidity, and some environments have high temperature and humidity. The performance and service life of the product will be affected to some extent if the product is in such a high temperature and humidity environment for a long time. Therefore, the product needs to be tested at high temperature and high humidity to understand its performance. If it fails to meet the requirements, the product needs to be improved accordingly.
