The function of the anti-static turnover box cover
There are many potential sources of stray electric fields: people, clothing, ungrounded turnover vehicles, displays, furniture, any ungrounded conductor, any insulator, electromagnetic interference, etc. The circuit boards in the open anti-static turnover box will have a few power supplies when transported by a grounded vehicle, which will also cause problems with the external equipment. Therefore, the anti-static turnover box should be covered with anti-static during transportation. The cover is still necessary.
Anti-static turnover box is a commonly used turnover device in electronics factories, but it is different whether the cover can be used. Does it need to be covered with an anti-static cover? It is usually necessary to cover the cover. The cover accurately placed in the turnover box can provide sufficient and strong shielding for the circuit board inside. These anti-static turnover boxes can not only provide the completeness of the machine under common use, but also provide external Provide ESD safety. If the cover is lost, any stray electric field can cause the numerous independent conductors on the circuit board to charge, and these induced charges are the source of ESD.
