Storage requirements for components to prevent static electricity:
When transporting components with leads, conductive foam material is typically used. This prevents high potential differences between component leads. For dual in-line package (DIP) components, static dissipative tubing is often used during bulk transport.
For circuit board assemblies, when located outside of an electrostatic discharge (ESD) protection zone, they should be transported in ESD-shielded bags or conductive handling boxes. Some packaging bags are made of conductive material, ensuring all components are at the same potential under stable conditions while dissipating any static charge that may accidentally accumulate on the bag. This method cannot be used for circuit boards with batteries. In such cases, packaging bags with a static dissipative lining and a conductive outer layer should be used. These bags are more expensive but provide excellent protection for both powered and unpowered components. Similarly, conductive boxes with internal rails holding the circuit board in place should not be used with powered circuit boards that have exposed connectors on their edges.
