Electrification

Electrification

Every substance has a positive and negative charge, and when two different substances are rubbed together or peeled apart, the positive and negative charges they each have are transferred, causing a bias of charge in each. The charge that remains untransferred and accumulates in a material is called static electricity, and the state of being charged with static electricity is called electrification.
When we touch something that conducts electricity easily, such as metal, static electricity is discharged all at once (the crackling that occurs when you touch a doorknob in winter)! when you touch a doorknob in winter).
When static discharge occurs in electronic components such as IC chips, they break, so countermeasures are required at manufacturing sites and other places. In addition, because charged materials tend to attract dust and other particles, packaging materials, films, lenses, etc. must also have countermeasures.
