In modern electronic manufacturing, electrostatic discharge is an invisible killer that damages sensitive components.The core value of anti-static electronic packaging boxes lies in building a safe storage and transportation environment through special materials.This kind of packaging materials are mainly divided into three categories: conductive type, electrostatic dissipation type and antistatic type.Conductive materials (such as plastics with a high proportion of carbon fiber added) have extremely low resistivity (usually less than 10^4 ohms), which can quickly conduct the charge to the ground terminal; electrostatic dissipative materials (resistivity is usually between 10^4 and 10^11 ohms) can slowly release the charge at a controlled speed to avoid sparks that quickly discharge; antistatic materials mainly reduce the friction on the surface of the material through surface coatings or additives. The electrical effect.

Its working principle is to build an equipotential shielding environment.When components with static electricity are placed in a box with static dissipation or electrical conductivity, the box body material can provide a discharge path for the electric charge to avoid the accumulation of electric charge on the components.At the same time, when the external electrostatic field tries to affect the components in the box, the conductive box body can play a certain Faraday cage shielding effect.It is important that the material properties need to be environmentally stable, that is, its resistance value should not fluctuate significantly with changes in environmental humidity, in order to ensure that it can still work reliably in dry autumn and winter or air-conditioned environments.

In the storage of sensitive components, the use of standard ESD packaging boxes is not optional, but a necessary quality management measure.Chips coming out of the FAB, PCB boards before assembly, spare optical modules, etc., in any waiting or turnover link, if exposed to ordinary plastics (such as ordinary PP and PE, which can easily generate and accumulate static electricity) environment, they may suffer irreversible damage.This kind of damage may be an immediate functional failure, or it may be a potential performance deterioration, resulting in an increase in the early failure rate of the product.Therefore, a full ESD protection system has been established from the production area to the warehouse, from delivery to customer reception. Among them, standardized and compliant anti-static packaging boxes are the key carriers for connecting all links and realizing “safety on the move”.Investing in qualified ESD packaging is essentially investing in product reliability and brand reputation to avoid huge repair costs and reputation losses caused by electrostatic damage.
