With the wide application of microelectronic components, the phenomenon of electrostatic hazard is becoming more and more prominent. Electrical and electronic products need to be tested for static immunity before entering the market, mainly to avoid the use of electronic products will be disturbed by static electricity.
Electronic products encounter static interference will generally appear the following situations: crash can not restart, crash restart after returning to normal, functional disorders, etc. , these are indicated that the product's static immunity is not done well.
In this case we will use electrostatic discharge generator to detect the static immunity of products, civilian electronic products we will generally recommend 20KV electrostatic gun, in GBT17626.2 standard, the highest level of air discharge is 15KV, so 20KV is enough for us.
In doing electrostatic immunity testing, the test project should be carried out with an electrostatic gun in hand, vertical subjects for incremental discharge testing, in the test process if the above-mentioned cases, we will determine that the test static immunity test is not qualified, and then carry out the corresponding rectification.
