For the prevention of static electricity, the storage requirements of components
When transporting leaded components, conductive foam is usually used. This can prevent a high potential difference between the component pins. For dual-in-line packaged components, electrostatic lossy tubes are often used during bulk transportation.
For circuit board components, when they are outside the ESD protection zone, they should be placed in an electrostatic shielding bag or conductive tote for transportation. Some bags are made of conductive materials, which can ensure that all components are at the same potential under stable conditions, and at the same time dissipate the static charge that accidentally runs on the bag. This method cannot be used for circuit boards with batteries. In this case, a bag with a liner that is static-dissipative and an outer layer of conductive material should be used. The price of this bag is higher, but it can provide excellent protection for powered and unpowered components. Similarly, a conductive box with a fixed circuit board guide inside cannot be used with a powered circuit board with exposed connectors on the edges.
